I need a little advice. I Am working on a SC it will not charge. The first thing I did was clean the commutator the brushes look almost new. Then I could make it charge by grounding the Field. It put out almost 8.2 volts. I took the cover off the VR the C/O contact would pull in ok. the other contact(top) would not. If I put my screwdriver next to the solid contact and touch the moveable one it pulls in and charges(as long as I hold the screwdriver there). I ran a separate ground wire to the VR case to make sure it was grounded. I bought a new VR and it makes no difference. I don't know what I Am missing.It has a 8V battery if that would make a difference)I usually have pretty good luck getting the older systems to work
Thank You
