Stuff to check, also experiencing dimming lights, in process of elimination, first with battery, removed it, charging it and then a burden test to check for bad cells. In between time, checked the DC buss bar for loose screws, wires, etc. pulled on wires and two broke off, screws were over tightened and cut through the stranded DC wiring. No load voltage out of the converter was 13.8 VDC which should be good. Connected an uncharged battery and initial voltage reading was 11.88 VDC. Will check again in the morning to see if it would get up to a more desirable level (12.5) I don't know the proper way to trouble shoot the converter or battery charging system. Any techies out there???
