I sure appreciate the ideas, after digging in to the fuse connections it appears the main DC fuse was damaged. Tested good across it and the bar in the sight glass appears fine, but the end had snapped off inside the laminated part. WTH? I'm ordering a new one today. We're getting the batteries tested to make sure they don't need to be replaced. If Y'all don't hear from me in a few days, it will mean we've resolved the problem
Thanks for the help!!
