88 C1500 5.7L 144K miles. I've only owned the truck a few weeks. It has been driven daily for the last two weeks.
Yesterday, took my son the park. The truck was parked for an hour or so. Returned to start it and there was no power. Nothing worked. There was no response from turning the key.
Another person gave me a jump start and took the truck home. Entire trip the gauge read 14 volts. At home, tested the battery with a DMM and it was at 12.1 volts. Truck started right up. Alternator is putting out 14.3 volts. Threw the battery on trickle charge over night. Truck started up and ran fine on the morning commute.
Does this sound like an intermittent voltage regulator failure? Is there a relay in the 12V system that could fail intermittently and cause a complete voltage loss?
Plan to trace the 12V power and ground wires tonight.
TIA
Eric
