Basically my battery died in my 89 Caddy El Dorado. Took it to sears and they replaced the battery and alternator cause it was bad. But to my dismay the digital dashboard no longer lights up any of it. After plenty of arguing no mechanic can fix it, but they have been trying to fix it mechanically. Does anybody no if i replace or take out and put back in the alternator if the dash will light again?Can an alternator change blow out a car battery or visa-versa.an alternator can take out a battery but not vice versa. Check your fuses.Can an alternator change blow out a car battery or visa-versa.They more than likely blew the fuse that lights your dash when changing your alternator (they probably did not disconect the battery properly before accidentally grounding out the ossitive cable) if you have a fuse guide for your vehicle, often located on the inside of the fuse panel or in the manual, see if it says which fuse operates the dash lights. Or you can just pull out the fuses one by one and see f any look burnt in the middle. This is one of those issues where moraly, they should be responsible, but it would be less hassle to just replace the fuse yourself :-( . Hope this helps ~ Dave ( Oh.. before you go driving around might want to check all of your signals and lights inclusing reverse and brake lights to make sure that nothing else is wronge) Can an alternator change blow out a car battery or visa-versa.no the reinstalling of the alternator wont fix it. and its possible that if they crossed some wires or the battery posts that it may have shorted the processor for the dash. Not knowing what all they have tested I can only offer a few thoughts. I would replace the relays connected to the interior electrical components as maybe one fried, I'd also check the dash dimmer to see if its damaged. then have the parameters run on the ecm to see if there are any fault codes.
