Question about 2000 Cadillac DeVille

1 Answer

Electrical problem with 2000 Cadillac DeVille.

I'm driving Cadillac with 135 K miles. Last year I ran in the problem with draining battery. After testing on dealership my alternator and battery were replaced. Because I’m driving this car everyday I did not catch this issue but when my car was in garage for one day (24 hours) battery was almost dead and car would not start and even crank the engine. I put charger on it and after that it was ok. But my car would not start after sitting for around 12 hours. I’m coming to work at 6 AM and when I’m leaving at 6 PM, battery almost dead. Charging system is working good and board computer showing 14.5 – 14.8 W. I bought this car used and it was aftermarket radio in it. After mechanics suggestions I just removed it from the car but it did not help. What it could be?
Second issue is my fuel gage. When I start my car in the morning it showing right level of fuel but when I start driving gage is going creasy and showing almost full tank. Looks like first half of tank it showing right level but when it’s going below mid of the tank it showing opposite level and up to full tank mark. I’m watching my fuel by millage but it’s real pain in the back.
And third problem is SECURITY light. Sometimes after I start my car light is staying on. After I restart my car light is going away. It does not happened to often but it does.
I spend time and money on dealership diagnostics but no results.
If somebody has any idea or suggestion pleases response.

Battery light followed by total failure on freeway. Autozone tested altenator and replaced battery earlier that day.


change alternator and maybe battery. Since the battery is pretty new, draining it like you say only took a year or two off its lifespan. Remember how your car acted this time, as most newer cars do the same exact thing when the charging system or battery needs service. In the future, you will recognize the symptom and know where to look before you get stranded.

My 1996 Cadillac Deville takes too long to start if it hasn't ran for a while, and when it does start, it runs rough for at least 15 seconds.


Check fuel pump & pressure,may be failing

Have you worked on the car at all, in the last couple
years, or just driven it,that could be a factor also

Why does my 96 Cadillac Eldorado battery keep discharging?


First step have the battery tested, a bad cell can cause a internal drain and kill the battery, if the batt is ok then check for interior lights like visors that stay on or interior light that come on by themselves at night due to defective door switches.

WHEN THE BATTERY LITE COMES ON THE DASH IT IS TELLING YOU THE VOLTAGE FROM THE ALTERNATOR IS WORKING, TO CHECK THE ALTERNATOR WITH A VOLT METER ON DC WITH THE ENGINE RUNNING YOU SHOULD GET A READING OF 13.5 TO 14.5 VOLT WHEN YOU TEST THE BATTERY TERMINALS IF THE VOLTAGE IS LOWER THEN 13.5 VO0LTS YOU ALTERNATOR IS BAD
