Is anyone very knowledgeable about delco generator parts here?
I've fully disassembled the original generator on my tractor and the for parts one that ended up being a cw spinning unit. The coils from the CW unit I can tell from powering with a bench power supply and using a compass needle that the cranking coil and the field coil are wound in reverse of the ccw coils from the generator originally on my 70. I can actually probably change how the wires connect to the field winding so it will have the same polarity as the ccw unit to use them since i was going to rewrap the coils anyway.
The question I need answered is are the armatures the same for both rotation generators? The cw rotating unit looks like the armature is a relatively modern replacement that has half the number of commutator contacts and had virtually no wear on it. The previous one probably was replaced because the pole shoes show wear on the pulley end from a worn out bearing on the pulley side.
I'm stripping the paint off all the parts and painting everything with ceramic black engine paint
