I have just finished reassembly on a 1957 Cub LB with a 6v generator and Delco Remy VR. I have no spark. Tractor ran before disassembly and painting.
I am performing a continuity check to see if I have maybe missed a connection or compromised a ground with paint. I have a good strong battery with a fresh charge. Full voltage measured at battery, starter, both sides of ammeter, and the "battery" terminal on the VR. The "F", "L", and "GEN" terminals do not register. Using the schematic in the back of the service manual, it would seem that there needs to be current at the "L" terminal which would then energize the ignition switch thence to the coil...etc.
Not completely understanding how a VR functions makes it a little hard to continue. I was wondering if someone could provide a simple explanation of how the VR works (keyword:"simple")? Does anyone have a schematic for my VR? Any help appreciated.
