Yeh that was one of the first things I checked out. It’s pouring the rain here so I can’t trace this out at the moment, but I did find a broken wire connector at the alternator. It’s in the same run with the ground wire ive circled in the pic. Not sure if this is part of my problem but I’m thinking it probably should be reconnected to wherever it goes.
