51 bolt- Just got moving, but I can say that the battery is 12v, and the coil must read 12v, and there is a ballast resistor on the firewall. I'll check the starter and generator today. Another question I forgot to mention. The coil has a green wire that's hanging off of the back (engine)side of it. Looks like it's been cut from a previous use. What would that have been for??
