I just got a 17 silverado and noticed today the auxiliary battery negative terminal is disconnected. The cap is still on the battery. The truck drove 4 hours home fine, starts and seems fine today. Why would this be disconnected?

On my 2006 Silverado LBZ I’ve been having a random issue where I’ll go to start the truck and it will need a jump. I’ll go start and it’ll just click but once I pull the key out and close the door the radio stays on a blue screen (aftermarket) and the dash lights up. I noticed when I turn the...

Having some electrical issues with my truck. Currently the Low beams are always on. I parked the truck at noon and then the wife said a few hours ago the lights were on. that means they turned on by themself. I pulled the relay which obviously turned them off, and I put a different one in that...
