Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner till early morning.
While these issues are occurring can you monitor the battery voltage to confirm it is within 13-15 volts?
Do you know which codes are stored?
Your concern could be due to incorrect voltage output from the alternator. 12 is to low and 16 is to high. Connections at the battery, alternator, and chassis can cause inconsistent voltage output.
