Electrical GURU'S

I thought I would start a new thread after doing some testing as the other one died.

So I got a chance to do some testing this weekend and found the following:

Under the hood fuse box
TBC Bat - 140MA
IPC/DIC - 330MA
HVAC - 130MA
SEO B1 - 330MA
TREC - 20MA

Inside Fuse box
DDM - 45MA

I took each fuse out one by one and read the amps across the fuse terminals.
Based on the figures above does anyone have any ideas of where to begin my troubleshooting.

I am just getting sick of buying batteries for the Hummer.

If your pulling those fuses then putting the meter in place you wake up that module and it will show a high draw. Best wy to check for draw is disconnect the neg battery cable and install a battery switch. turn the switch on and let sit for about 10 min. install the meterr across the switch then open it so the current flows trough the meter. Then if you have a high draw start pulling fuses.
