It could be the hood latch isn't engaging all the way and causing the hood light to stay on and create a drain on the battery. My grandfathers car (same year/make) had this issue and we used a bungy cord to keep it shut all the way and the problem is gone now.

96 cadillac eldorado etc battery not staying charged when the car is started the battery goes up to 14 when driving and press brake voltage drops 11-12(car may even die) and to 13+ if u give it gas

Does the vehicle start after sitting over night or do you need to jump start it . Is the charge light on ( batt. symbol ) at any time ? Serpentine belt good , tensioner good ? Battery cable connections good an tight and no corrosion ? Battery also good ? That is normal for battery voltage to jump up to 14 volts after starting , alternator is replenishing the battery after starting ,that draws down the battery . Going down to 11 or 12 volts when stopping and almost stalling isn't a charging system problem . You have a idle problem , IAC - idle air control valve or dirty air passage , a vacuum leak . Giving it gas and it going up to 13+ the alternator is working . Your best bet take it to a qualified repair shop and have it check .

When I try to start my 1989 cadillac eldorado why does my dash go out and car won't start?

The battery is dead and/or the connections on the battery posts are corroded. Remove the battery post connections and clean the contact surfaces with sand paper and reassemble. Charge the battery while you have it disconnected and after cleaning and reassembly it should work fine. Batteries do get old so yours may need to be replaced if it will not charge.

I have a 1994 Cadillac Eldorado Touring Edition with just over 40,000 miles. It has been sitting for a couple of months and now when I start it it comes up with the message "No Battery Charge". ...

could possibly be the altinator is not charging ,check your fuses first that have anything to do with caharging they should be marked if not your manual with have that and if they are ok then get your charging system system checked by your garage

Battery was dead and had to jump start and then the car did start OK, but then the car alarm came on and now won't shut off!!! This car was bought used and has no key fob...just the key with the chip...

it will need it to be disconnected. have a shop or alarm shop disconnect it, wires may have to be spliced back together for everything to work properly, you cant just unplug it.

Battery charged but will not start without jump

Have your alternator checked at one of the parts store around your area. They will check it for free. The next thing would be to have your battery checked. If you need a jump after the battery has been charged, you may have a dead cell. The alternator charging the battery....will not charge the battery for the next start.

Battery issues

It would take a good mechanic about 15 min.- 1/2 hr., to test your charging & starting system for you. Could be a faulty battery, or wrong battery for your car, bad connection, system not charging, or some kind of a current draw is taking place while sitting like , lights on, etc.or even a worn starter. If you have your own ( DC volts ) multimeter or a friend has one, we could walk you through what to try. What size CCA does it say on top of the battery?
