08 C2 Thomas,Freightliner, 7.2 Mercedes Engine. 7 windows
Will not start. Turns over strong, but will not start. All 3 batteries are fine.
I have been building it out. Removed (carefully) and connected back all wires to rear door, and handicapp side door. It was starting fine. I was starting it up every 3 days to keep my batteries charge up.
Any suggestion anyone?
