OK, I'm chasing a battery discharge problem on my Colorado. If I park it for 2 weeks the battery goes dead. A new battery does the same thing.

I threw an ammeter on it and find there is a continuous 50 mil drawn. I do not think the is much too worry about.

Then I opened the door with the interior light turned off and the draw jumped to 250 mils (1/4 amp). That draw stayed there even after I closed the door. I think I woke up the BCM (body computer). A few minutes later the draw was back to 50 mils.

After that I touched nothing and checked it about 10 minutes later. The draw was back to 250 mils again. I think something is waking up the BCM periodically.

Anyone out there know what one of these things should draw when turned off and nothing going on?

Also has anyone ever seen anything like a recording ammeter or recording milli-ampmeter?

What also confuses me is I left a 13.2 volt 500 mil battery tender on the Colorado while I was gone to Quartzsite. When I returned 2 weeks later the battery was dead again.

I can park my GMC all winter and not run the starting battery down. I park this Collie for 2 weeks and the battery goes dead.
