06 CTSV

I've been having a few electrical gremlins. Nothing major, just annoying crap ... starter, starter pigtail, battery, blinking HVAC display ....

I'm curious what voltage others are seeing on their display?

Mine is always between 14.3 - 14.7

That seems awefully high to me.

 

I see around 13

 

14.3- 14.7V is normal i see those numbers on mine also. Check all the grounds especially the ones behind the pass side head, i had similar issues and it turned out to be that. Wouldnt hurt to clean the ground contacts.

 

14ish is normal for most GM vehicles. It's how you tell your alternator is working. If you show 12 volts while running, it means you will soon be stranded on the side of the highway... Learned that one the hard way.

 

Every vehicle I've owned with a 12V system had the voltage regulator max at 13.7V

If the battery was low, it might spike at 14.3, but come off of it quickly as the battery is charged.

I have a new battery and I've had my electrical system checked at two independent shops, each giving it a clean bill of health.

Thanks for the replies
