pull the stereo code before unhooking battery post type of vehicle and i will tell you how to get it

You Have 2 min out and in before you lose code. turn in radio first to fill capasitors then shut down out and in turn on radio
An adapter that uses a 9 volt battery that plugs into the cigarette lighter socket allows the memory to be saved.



Look to your local auto parts store.
contact hyundai
You'll need two jumper wires (12 ga) with clips. set the new batt on top of the engine and clip the jumpers (not jumper cables) pos to pos and neg to neg. Now, being careful not to knock off your jumper clips, remove the old bat, put the new one in place and carefully hook up the cables. As long as you don't break the connection you'll be okay.
sparky 34 is correct.
you need to find a memory saver.it uses a nine volt batt. and plugs into the cig lighter.I got mine from MAC TOOLS but try sears.
it depends on the make of the stereo to begin with, I would check with Hyundai to make sure that a temporary power loss will not affect it. (usually a few seconds during changeover). I had the same problem with my blaupunkt this afternoon as I had to change my battery. The stereo will store all other information, but will need a code to activate.



As far as the Hyundai stereo goes it might not need a code, if it does and it is factory fitted, then you will have to call Hyundai and give them the VIN or whatever they need to locate the right code. Alternatively, there might be a way of jury rigging it with just some temporary wiring, attach just some thin wires to the terminals of the new battery and tie them to the terminal cables of the car so that when the old battery is removed, voltage is at least not interrupted until you can lock the terminal clamps down again and take the temp wires off. This will maintain a constant current and fool the stereo into thinking that it is the same battery and that it wasn't taken out or stolen or anything.



The reason that radios code like that is to prevent theft, they rely on constant current to maintain their memory and to keep the code active. If the current (power) is cut, the radio code is inactive and the radio thinks that it was removed from the car (possibly stolen). That is why.

Ok heres the problem..i wired 4 underdash led lights directly to my car battery?

i put the two wire to the positive and negative and the kit came with a switch. when i went to start the car the battery was dead..after jumping it i drove the car for 10 min, shut it off and it wouldnt start again..i just changed the battery and it is fine...could i have blown out the alternator by hooking the wirees to the battery or just really drained the battery?Ok heres the problem..i wired 4 underdash led lights directly to my car battery?I would try unhooking them, jump start and see if the battery comes back up.

Did you put an in-line fuse in the positive wire close to the battery? If not you have too much wire, not protected by any fuse and could get a dead short and a fire.
Ok heres the problem..i wired 4 underdash led lights directly to my car battery?
You drained the battery. First of all find your fuse block. Then locate a space in the fuse block that is not being used , Make sure it is only hot: meaning there is only power to this space with the key ON. Get a cuircut testor they are very cheap. Run the positive to the fuse block and find a good ground: bare metal not aluminum, steel and make a good ground. If you would like to install the switch, put it in the hot wire where ever you like. Hope this helps.

Can not changing your oil cause the alternator to overcharge the car battery?

There is no relationship from engine oil to an alternator. The voltage regulator inside the alternator has gone bad. Replace the alternator.



good luck.Can not changing your oil cause the alternator to overcharge the car battery?No , not a chance. The voltage regulator, ( probably within the alternator ) is the most likely problem
Can not changing your oil cause the alternator to overcharge the car battery?
Of course, change your oil immediately to fix problem if it is not too late.
Can not changing your oil cause the alternator to overcharge the car battery?
Hi,



Firstly, there's no relationship between the engine oil and the alternator. Forget about the engine oil change or it's effects on your car's electricals.



Your problem is here: The regulator is not a part of the alternator. It's a separate unit. It's designed to *cut*off* power from the alternator when the battery is fully charged. Your car's regulator is not working. It's broken. That is why it continues to supply power from the alternator to the battery. You need to replace the regulator *not* your battery.



The mechanic who replaced the alternator is either dishonest or a dimwit. He should have told you to replace the regulator *not* the alternator.



Go, fix this.

Car Key Fob battery change - Do i need to reprogramme it again?

I have a Fiat Bravo 1.2 (2001)...i think the battery went dead months ago and i only just changed it, but it doesn't work, so does it mean i have to reprogramme it? How do i reprogramme it, can i do it myself or do i have to go to a specialist Fiat Garage?



Thanks.



(I asked this earlier but no answers yet so i asked it again)Car Key Fob battery change - Do i need to reprogramme it again?Hello



Yes you have to re program it

If you have the Owners Manual it will tell you how.

Normally you have a certain amount of time from the time you take out the battery to getting the new one in so you do not have this problem. But you have to change it before the battery looses all power.

Car Key Fob battery change - Do i need to reprogramme it again?
yes it has to go into fiat very few people have the software to re program the keys and they cannot re program one key only there has to be two and they cost 拢135 each that's how much i had to pay for a spare key for my multipla last month if you loose both keys it mega money to repair as you have have a new ecu .
Car Key Fob battery change - Do i need to reprogramme it again?
yes u do have to reprogramme it,you might be able to do it urself have a look on the net and u might find a site that will tell u how to do it,if not then yes u will have to take it to a fiat garage for them to do it.
Ask the question on this web site you might have a better response.

How do I keep my car electrics live whilst I change the battery without losing my radio code?

you can hook up jumper cables to the battery cables.How do I keep my car electrics live whilst I change the battery without losing my radio code?u can buy a 9 volt battery plug in deal thats goes in ur cigertte lighter there like 5 bucks but it uses a 9 volt battery
How do I keep my car electrics live whilst I change the battery without losing my radio code?
I have heard that a 9volt battery will help, I think you make an adapter with a cig lighter plug on one end and 9 volt clip on the other end and plug into cig. lighter socket. I am not 100% sure, cause this is only what I've heard from somewhere. Wait for another answer, before trying mine. I have not tried this myself.
How do I keep my car electrics live whilst I change the battery without losing my radio code?
If you dont have the proper backup tools then you can connect a battery charger or jump leads on to your cars battery leads before you disconnect the battery but be carefull not to touch the positive terminal against anything earthed
If you make up a couple of wires about 2metres long with crocodile clips on both ends, before you remove the leads from the old battery prior to taking it out of the car you can clip one end of each wire to the battery connections and the other ends to the battery terminals themselves (you may need a second person to ensure they stay on when moving the battery), you can then remove the old battery and replace it with the new one, keeping the wires connected to the old battery. Once you are sure you have connected up to the new battery you can remove the crocodile clips from the old one! - job done.
do it the easy way . just leave the engine running
DO NOT - DO NOT - DO NOT - disconnect the battery with the engine running. It will cause a power surge and could blow expensive electronic components.

All you need as described before is a pair of jumper leads. Connect the jumper leads to the battery terminals you are removing and to a second battery along side the car ( pos to pos and neg to neg).

You can now remove the car battery keeping the jumper leads connected to the car terminals.

It is easier to remove battery clamps (retainers) and loosen terminals before connecting jumper leads.

Be very careful that the jumper leads or terminals do not short to ground or each other, wrapping a piece of rag around them would help solve this.

Re fit the new battery and connect terminals before disconnecting the jumper leads

Job done, no loss of codes or memories.
By what ever means - you need to keep power to the radio via the car wireing.
It would be easier just to find the code for your radio........
what you could do is connect the battery charger to the battery leads.tell everyone what you are doing so they don't turn off the switch or electric.but care is needed to not short out on the body work when thebattery leads are disconnected from the battery but still connected to the carger..so a old large cloth placed over the relevant part of the engine and body..to act as an insulator is prudent....remember the cable are a trip hazzard....and keep the doggie away as they will just walk though the cable....how do l know this..lol.
if you put a battery charger onto the leads to the battery this will keep power up
You can use jump leads or a battery pack (like the booster packs ) connect these to the leads before undoing the bolts but be careful not let them touch the body work or together.

How to check which cell has a problem in a car battery?

I changed my car battery last year. But in this winter, the battery keeps being drained. I had the people from whom I bought the battery from checked it. they said somewhere is draining the battery.

Now I had the battery checked by a service dealer. They said one of the cells in the battery is bad.



How can I tell who is telling the truth? Is there a way I myself can check the battery? How to tell a cell in the battery is good or not?



BTW, I think I am pretty technical oriented and like to buy some small tools to do it.



Your input to the question is highly appreciated.How to check which cell has a problem in a car battery?You can buy a battery tester and check yourself, if the battery is not sealed when it is fully charged remove the covers or screw plugs and tap along side of battery with handle of screw driver not the sharp end, you will notice bubbles rising in the cells if they are ok, if there are no bubbles that cell is dead and you will have to replace battery
How to check which cell has a problem in a car battery?
Really you can't. The battery case is sealed. So just get another battery. You can't revive 1 cell, just replace it
How to check which cell has a problem in a car battery?
Single cells don't usually break down in a car battery; if they do, you can usually tell by the lower level of water in it. Maybe you'd like to check the level(s) first, if necessary, refill with de-ionized water, then check the density of the water/acid mixture with an areometer, these are rather inexpensive. Try to recharge the battery overnight, making sure not to overcharge it, then check again. Next, however, make sure your generator works properly; very often, a faulty generator causes such problems.

GOOD LUCK!
A battery usually doesn't go bad in just one year. If it is low repeatedly, it usually means the alternator is failing to keep it charged. But that should be signalled by your %26quot;Battery%26quot; or %26quot;Alternator%26quot; warning light staying on all the time on the dash. Or it's trying to charge but there is corrosion on the battery connections blocking the flow of current. You can disconnect the battery and look at the connections and see if there is clean shiny metal to make contact, or if they are covered with discolored corrosion. There is a special double wire brush ($3.50 at Walmart or the parts store) that does sa good job. The battery installer probably took care of that when they did the battery.



If the dealer said one of the cells is bad, they could have shown you how they arrived at that conclusion, maybe by testing the cells individually with a battery tester (hygrometer-not expensive), which you can do yourself if the cell caps on top of the battery can be removed. Be careful! You're dealing with sulfuric acid! Check the fluids per the directions and rinse the tester off and out, and don't drip it on the carpet or your clothes or hands or shoes! Having a cheap container of water at hand to rinse it in would be a good idea.



You can test the alternator by using a VOM (Radio Shack or Sears or Harbor Freight, under $10) on the battery terminals, set to the smallest Voltage scale. It should read 12.5V, or 13.2V, or something like that. Then start the car (which drains the battery a little) and measure again quickly, while the alternator is pumping current back into the battery using a higher voltage. It should read a volt or two higher than before, for a few minutes, anyway. If it doesn't, the alternator may need changing. A large auto parts store will test it for free, Advance Auto, for one, will test it while it's still on the car. Of course, I had a Toyota Corolla once that wouldn't charge, and it turned out that a lone wire running down beside the engine, with an in-line fuse holder that was completely corroded, was at fault.



Wish you the best!

Mike
Assuming your battery isn't sealed, (I know mine aren't) you can check for a dead cell by a specific gravity test. They sell the testers (hydrometer) real cheap. They suck up the fluid from each individual cell so you can compare them. If you have one that's more than .050 lower than the next lowest one, that cell's dead.



Checking for a drain, if you have an ammeter, connect it between the negative battery terminal and post with everything off. It shouldn't read more than about 250 mA. If it doesn't have auto-range, be careful not to open the door, or accidentally honk the horn.



If all you have is a 12 volt test light, you can make sure it goes off after you unplug fuses for everything that should have a drain, like ECM, radio, BCM if equipped, etc.. If it doesn't go off after that, keep unplugging stuff until it does, to isolate which circuit.



P.S. also take out the bulb on the under-hood lamp if you have one.
It won't do any good. If the battery's bad, you need a new one. You can take the battery to a parts store and have it tested for free or put the battery in another car and see if it does the same thing.

Can a simple electric motor like a clock or toy car change direction by turning a battery around?

A toy car motor is usually a permanent magnet motor so yes.



A battery clock is not driven by a motor and a mains clock has an ac synchronous motor so no and no.Can a simple electric motor like a clock or toy car change direction by turning a battery around?If it's a DC motor - most likely it will reverse direction when the polarity is reversed.
Can a simple electric motor like a clock or toy car change direction by turning a battery around?
I know some can. When our kids were small, we had more than one battery-operated toy that rolled, walked or crawled which could be made to go backward by reversing the batteries.



Reggie the Turtle was the best one, and we kept him.



I've never seen it on a clock, though.

proabably not because then it just wouldnt work at all.
*****
On a DC motor the direction has to do with the direction of the current. Like the power window motor in a car. The switch determines the DC direction so the window will go up and down. By switching the + and - the motor changes direction. Also the amount of voltage to the motor changes the speed.
no. only in a DC power it can change direction. if you are using bettery to power the motor then it will not because the current will not flow through. in AC the current only flows from positive to nagative dirction. you can build a cuircit to convert ac into dc or dc into ac. if you can build a cuirct to convert you bettery power in to DC it wiil work. Note! working with DC power is dangrouse even at 3V bettery suply.
