I have an '07 Chevy Avalance LTZ.
I checked all the fuses with voltmeter when the truck was off - everything showing 12V I put a black mark on the fuse with a sharpy.
I started the truck up, and then went with the voltmeter on all the other fuses - they STILL showed ZERO volts. !!??
I need to find at least one fuse that is powered ONLY when the truck is on. Of the maybe 15 fuses, there's about 10 that show 12V when the truck is off and keys are out, and the rest still don't show anything when the truck is running (or keys turned to ACCessory).
What am I doing wrong?
