Hi, I have a parasitic battery drain of nearly 8 amps on my 2008 GTC. I have connected my multimeter and been through every fuse in all 4 boxes. Some give a minor drop but I can’t find the culprit. The main battery is new but will go flat in about 48 hours. I have my conditioner on it when not driving and when I dont drive the car for say 5 days the battery will still be below 12v. Installed Denision BT Lite yesterday and so had all the AV equipment disconnect for a few days and that made no difference. Any suggestions before I call in the cavalry? Thanks Tim

 

Dude it’s a battery control module which is located behind the left side battery (house battery) I’m 99% sure this is your issue, replace it and it will be fixed.

 

Have you had a bad BCM . I'm interested to hear other symptoms. I suspect my BCM is faulty but haven't got arround to doing anything about it atm.
