This was the greeting from my DIC this morning and the IC voltmeter confirms it.
Zero fault codes according to Torque Pro.
So I put the truck where it needed to be to unload it and will proceed with fixing the issue.
241,000 miles on the truck. What's the most likely thing? Ran great yesterday. Alternator? That's of course my first thought and will have it tested. Anything else I should look for?
The GM alternator that's in it right now is the original as far as I know. A quarter million miles isn't bad, but is there an OEM that's a better unit for a comparable price?
