Random complete loss of all electrical power overnight
A few things to note… I’ve checked that the alternator is charging at exactly 14 volts, so not over or undercharging to my knowledge. The two things I’ve noticed so far in these two days of driving that could be remotely close to a potential cause are: 1. My gauge cluster - Not only does my...- Stevalli

Random complete loss of all electrical power overnight
Thank you to those who have replied so far. The multimeter was set to its 10a setting. I know that the multimeters fuse is good because it initially reads high when the computers systems cycle, but it falls to a very low number. I was worried to put it to the 200ma setting because of that...- Stevalli

I did pull off the terminal connection covers and clean them off on my last go around with this, and that didn’t...- Stevalli

Random complete loss of all electrical power overnight
Hi everyone! I am new here, but I am finally tired of putting off getting my Tahoe fixed. It’s a 2003 5.3, and for the past year and a half has been giving me the strangest electrical problem. Basically, it started when the truck sat for about a month because my window got smashed and I just...- Stevalli
