Hello everyone. I have a White tractor with Fiat motor and electronics. It has a two connection voltage regulator and I don't really understand how it all works. I need to start, because the mechanic bills are killing me.
I found a 1976 Fiat Spider wiring diagram that seems to represent the system very well (even the terminal numbers are the same). I eliminated all the car stuff, with the exception of a couple of items.
A couple of questions, if someone would be so kind:
1) In addition to the battery cable, there are three wires going to this starter. The relay to the key is obvious, but what do the other two do?
2) The Green wire, the Field connects to the fuse box, but so does one of the battery wires. Why would that be?
3) Most importantly, what does the Y/R wire (White connection on the alternator) do and where should it go?
Overall, can this be simplified further?
The Modified Wiring Diagram:
The Alternator:
Thanks to anyone that can help. I don't want to go through another hay season having to pull start the tractor every day.
The original diagrams that I built mine from are here:
