[andbro]

Hello

My battery is new,
The starter is new,
The alternator charge very well.

Sometime my car don't want to start. The battery is completly discharged. All lights are off ( inside and outside ), the radio off; all is off. I boost my car and it start. I have the peace for 2 days, 1 week...

i don't know where search

thanks

Battery drains can be time consuming to find. First try every single electrical device (bulbs, motors, etc...) & see if anthing doesn't work. Start there.

I had the same problem. I turned out to be the sensor for the cooling fans, it would not shut the fans off.

Yeah my problem was the seat belts. For some reason the motor turned on periodically after I locked the car. Had to disconnect the seatbelt.
