Expert:  Chad Farhat replied 1 year ago.

if you have local shop can do it, igntion switch off ,and check the fuses that is keeping power on the mafter the car is off ,wiil be the source of the battery drain, they have to check all fuse boxes inside the cabin and under engine compartment

Expert:  Chad Farhat replied 1 year ago.

usually , a switch or module is shorted out and staying on at all times ,and draining the battery, we just have to find which one

Customer: replied 1 year ago.
I'm good. By the way, alternator checked out fine.
Customer: replied 1 year ago.
Sounds tedious. Where to start?
Expert:  Chad Farhat replied 1 year ago.

they can hook up a test light to the battery and pull each fuse at a time ,when the current draw drops , the fuse the pull will be the bad circuit, so if the pulley , turn signal swicth fuse and voltmeter showed no more drain than switch bad or the wiring to it as an example

Customer: replied 1 year ago.
Is this process expensive? Sounds very labor intensive to me.
Expert:  Chad Farhat replied 1 year ago.
