Hi I have a 1992 Buick Regal Gran Sport with a V8 3.8 and for the last few weeks my car'* battery is drained to around 3 amps. The first time it drained completely and no lights turned on and no beeping when I opened the door with key in the ignition. I called AAA and the guy gave me a boost and said it'* probably dead cells in the battery. So two days later before I could bring it in to see my mechanic it was drained again so I called AAA again and got their battery service where he checked the altinator and battery and it showed the guy 2 dead battery cells so I get a new battery and for 3 days everything is fine. The fourth morning same problem, the AAA guy is puzzled cause he is getting same readings when he put the new battery in. I take it to my mechanic and he charges it over night and the next 2 days it starts fine and thought it was the radar detector that came with the car when I bought it. Two days after getting it back from my mechanic, it'* dead again with only 2.7 amps. Can someone help me, cause I've checked the trunk light and glove box and they are not on when I close them.
Thank you

J - Welcome to the forum!
I assume you are not leaving anything charging etc or plugged in overnight are you?
Temporarily you may want to plug into a battery charger overnight, until you find the drain down. Probably the easiest way to find the guilty circuit is to use a voltmeter attached to the battery, or accessory port, and start to pull fuses one by one until you find the voltage remain steady, indicating the circuit responsible.

Thanks for the suggestions, no i don't have anything charging. I will try that

No Problem J let us know what u find out.
Please Refer to your owner'* manual for for the specific fuse panel* locations for your car.
