She's still not running...
I built the bracket and installed a new 3G. It looks solid. ran it and NO output... I have to figure out how to wire it correctly. i ran out of daylight so will continue tomorrow.
After reading more wiring diagrams and interweb posts, I think I may need to remove the relay that the old Leese neville was wired to, which controls the AMP warning light, and just hook the grn/red wire from the 3G volt reg to the grn/red wire that comes from the cab (which goes to the relay). We shall see tomorrow.
Has anyone done the swap from a Leese Neville alt to a 3G? It seems that the wires from the Leese do different things than the wires from the 3G, and it is not a simple plug and play. I need to figure out what the orig wiring was bfore the amby mods and try to get back to that. I am thinking that the only wire that originally came from the cab to the alt was that grn/red wire. Can anyone confirm this? Or tell me how the orig alt would have been wired?
Thanks for all the help so far.
