Check for the terminals for the battery and the alternator first. The alternator may not also be delivering current properly. Check the belt drives. Other than that it may be a bad alternator.

I have a Cadillac deville 1998 v8 northstar. I had my alternator rebuilt and got a new battery. Vehicle started once but dash read battery not charging. Took vehicle to O'Riellys Battery tested bad. H


When you replaced battery you activated the system. Need to read owner manual and see if it tells how to deactivate it. You may need to contact dealer to deactivate it.

I have a 1998 Cadillac Deville. I replaced the battery, and alternator. Its still not charging properly. The service charging system light is on on the dash. Can you tell me what else could be wrong?


Sounds like a faulty voltage regulator to me.Start the car and take a multimeter and check voltage coming out of the alternator it should be 14-14.6 volts if its not within these specs take alternator back and get a new one.

Mwont start after driving, until it sit for at leAST 1HR


Could be a overheating problem,The charging system isn't charging the battery back while you are driving the car.
Have the charging system checked first,batteries can recharge by themselves to re start the car in about a hour

Dash says battery not charging


Alternator is what charges the battery. The alternator isn't putting out enough of amps to charge your battery and you will get a light or gauge reading that the voltage is low.

Service charging system


You need to get an opinion from another repair shop. Look for one that is ASA certified.

Check charging system


So you have a new alternator. I S IT CHARGING ? If the answer is yes , and the battery still dies, I would say there is a 12 volt drain in the electrical system. Hope this helps

98 cadillac deville battery wont hold a charge


sounds like a 12V drain on the system, like a trunk or glove box light that won't shut off.> Could be many. many other reasons why. The way I would find the draining circuit would be to remove the neg cable of the battery. I then would connect a 12V test light between the neg battery TERMINAL and the neg battery CABLE. With a 12V drain the light will shine. I would install into the light a 9V battery powered recepticle to hold computer and radio station memory. Then I remove fuses 1 at a time, then reinstall, at the same time looking for the 12V light to go out. Hope this helps.
