1992 Buick Regal battery drain, after new batt & Alt ok
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
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.
