Decided this weekend to replace the battery and also had the Alternator fail the regulator test. FIgured between the two I would easily solve the problem. No such luck. Came out today and dead again.
Suspect at this point it has to be parasitic draw. Any thoughts on some of common suspects for this. I do realize it could be just about anything.
I just pulled the fuses tonight for radio and onstar to start the process.
Thanks again all.
think it was back on my 1st power issue, since I had a brand new HID light setup connected directly to the battery, I assumed it was good. I was testing **** for days...by chance buddy of mine noticed the headlight realy was warm... That was my draw. My point is dont assume anything, test it all and keep the variables consistent.
You need a good digital auto rangine meter to do this. When you first turn the truck off it will be in a higher amp range, which will drop down to a lower range after 10 minutes or so. If your not sure what your doing, you'll smoke your meter.
Someone posted the mah draw numbers a while back on all the common circuits that retain power when the vehicles off...I used it tracking down my issues. Might of been Easy Ed.
Did you try searching the forums for "parasitic"?
Radio Fuse is pulling 1.1-1.2A key out, no power to truck
Radio Sub is also pulling 1.0-1.1A key out, no power
I am guessing this pull is out of bounds...
