OK Guys, latest update.............not that good. My statement of having working glow plugs was incorrect. It seemed to work that one time but not since. Further investigation showed me something that made me really scratch my head. I seems that the "field fix" was a wire from the battery ground post up to the momentary switch on the dash panel(not a factory switch or wiring) then to the glow plug bus bar!!!!!! How is this going to provide any power to the glow plugs?
Would seem to me glow plugs would be grounded at engine block and busbar/wiring to glow plug terminals should come from positive side of battery through the push button (or master power switch) .....
