Hello, I’m not so good at troubleshooting electrical stuff, so some simple steps to start before I hand off to my mechanic would be awesome... I have a JPI930, and it shows 13.0-13.3 volts pretty consistently. If I put any draw on the system, it sits at 13.0. I’m talking transmission, pitot heat, LED strobes, any one of those is noticeable. Generally sitting at ~3-4 amps as I don’t have much draw. Battery is new as of 2 months ago. PP alternator was new from last October annual.
