The alternator gauge on my M931 seems to work properly and normally reads in the green but I noticed a few days ago that it's reading in the yellow.
It's got new batteries and they're fully charged since I keep a solar battery maintainer on it.
I checked voltage at the batteries (engine off) and got 24.5v.....checked again with engine running and got 24.1v.
Not sure if that's a valid check.
Can anyone tell me the how to meter test the output at the alternator? I was looking at the P2P program but it doesn't seem to have a way to set it for an "engine running" condition so that I can see the voltage at the alternator wiring.
