Battery drain issue
Winter always seems to highlight any battery issues and I'm seeing some drain on my batteries as well.
Now I haven't tested my alternator diodes but with both negative battery cables off and using my DMM on 10A I still get around 0.8A draw and I have been able to account for where it all came from by pulling fuses (underhood fuse panel) and testing the current draw (with the truck off) at each junction.
Here's what I found:
TBC BATT = 0.06A
CIG LTR = 0.21A
Radio = 0.02A
PCMB = 0.01A
IPC/DIC = 0.56A
HVAC/ECAS = 0.05A
So my question is are these readings normal for an LLY (esp red ones)?
If someone could verify on theirs and post what they found, I would certainly appreciate it.
