I've got a 900 series with a serious electrical problem. I'm sure I have a ground somewhere, but I'm having trouble figuring out the wiring.
My tractor has an ammeter. It does NOT have a Voltage Regulator, but does have a resistor block.
I've tried to compare the wiring to the diagrams in the 900 series repair manual, and it looks like it's a combination of the 6 and 12 volt system. Perhaps a conversion?
At any rate, I thought I had fixed an original problem by replacing the key switch. Originally, with the key on, I got 12 V at the Starter motor relay, but only 4 volts at the starter switch. Cycling the key switch, eventually 12 volts would show up at the starter switch, and I could start the tractor.
Now, with the key switch off, I get 12 volts at the starter relay. Key switch on, 2 volts.
Starter motor relay has 4 terminals. Battery, starter, starter switch, and key switch.
Does anyone have a wiring diagram that this looks like? It's not the standard 12 volt (no lights) nor the standard 6 volt (no regulator). It does have a resistor block. Any help would be appreciated.
