Possible starter wire issue... 05 C6
Had the service charging error appear in the coffee drive thru with a seat heater on, defroster, fan defroster, lights on, stepping on brake and 750 idle (bumped it up from 650 to pre-empt low voltage issues). It had rained for 5 days straight so lots of moisture for past week.
Sunny today. Drove at lunch, no issues, but not loaded. Did a load test with voltmeter @ idle with everything on and noted the readings on the first line.
I will try to pull any codes tonight with hp tuners, but so far wondering what to test...
