Schematic for 7020 three wire alternator

[RevJJ]

Got too close to a branch and pulled out the three wires that go into the alternator on my 7020. Anyone have a wiring diagram of what wire goes to what post...the wires are white, black and green. I know one of them is for the tach, just not which one. it didn't help that the diode shorted out and it doesnt' charge anymore, either.

I can't tell you the color code, but here's how the wires go, by function:


The wire that is "hot" all the tine, key switch "ON" or "OFF", goes to the #2 terminal.

The wire that is ONLY "hot" with the key switch "ON" goes to the #1 terminal.

The tach wire goes to the terminal offset from the #1 and #2 terminals.
