Help- Rewiring TO20

Orville Cox · Feb 11, 2015

Please Help- Rewiring TO20, Need a diagram that shows the gauge of each wire. It is 6v, positive ground, charging light on dash, lights front and rear. Diagram with ampmeter would be fine if it shows the gauge of each wire. Found several diagrams but none shows the wire size. Many Thanks up Front.

Use 16 ga.wire for gauges.

I'm assuming you're going for function, not by the book original...

If I were wiring it, I would use #10 from the battery to the amp meter, and # 10 from the amp meter to the generator. The rest would be #14.

Best to use automotive or appliance wire. It's finer strand, more flexible, vibration resistant.

Try Agri-Services at www.wiringharnesses.com for a new exact-as-original wiring harness. They made me a sweet harness for my 1939 early Ford-Ferguson 9N tractor that included the correct gauge and color coded wires; correct wires to the dash mount key switch, ignition 'ON" lamp, square voltage regulator, and the small two-wire 'A' generator. My cost was $96 with shipping included. The 9N and TO20 were pretty close to each other so I'd call them and talk to the guy -very friendly and knowledgeable fella. Also, the FENA guys have a very smart fella too in their technical guy, Robert Sybrandy, so try them as well. I know you get a lot of schematics and tech stuff from them.
