Tractor wouldn't start after having used it daily baling hay. Found that the starter relay and main fuse and wiring melted. Got new parts, but since the wires are disconnected/insulation melted, not sure how to wire it back. Anyone have a wiring diagram for a late model 12v (1971) 3020 diesel? Thanks!
Dealerships were not helpful, claimed they were not able to print any diagrams.

Are you working with the relay inside the steering pedestal at the LH side? Or?

I don't recall there being a fuse there?

What is the part # of the new "relay"?

Was the old one a 3-termianl relay, and the new one is a 4 terminal relay?

3020 could have the standard metal three terminal starter relay or the optional plastic cab-kit relay that uses a four terminal relay. Whic
do you have? The original setup uses one main Klixon breaker I thing was rated 30 amps but I would not swear to it. Deere part # is
RE164448. If you do not have a cab and have the standard starter relay and breaker - wiring is easy.
