Wiring diagram for a vintage 4320

[svdsinner]

I love the 4320 that I recently purchased, but within a few hours of usage, the lights stopped working. I bought the service manual recommended by JD, but it doesn't have any electrical diagrams for anything except an early 4020. Those diagrams help, but 4320 wiring is different enough that I'd really like an accurate diagram. Any idea where I can get one?

Also, what do the three ON positions of the light switch stand for? If I'm reading the.faded markings correctly they are labeled B, L and D. What should I expect the lights to do in each of these positions?

Shoot me a message with your serial number. This will insure the correct information. I could send you something in black and white via fax or I could try to hardcopy color drawings and mail them.

I have had trouble with the lights on mine too. Once it was the ground. Once the connection at the battery was corroded. Right now mine has a bad switch, I bought a new one from Steiner Tractor Parts when I got replacement battery boxes from them. Does yours have two 6volts? The switch positions are for front lights, front lights/flashers, fronts/flashers/rear on my tractor.
