Re: 292 Questions
The 15.4V could be from the battery being low and getting brought back up. If I read this thread right, he's been doing a bit of cranking which could lower the battery voltage. I was taught that minimum charging system voltage is 13.5V to overcome system resistance with enough voltage to charge the battery.
