1986 Western Control Wiring
 

I need the electrical control diagram for a 1986 Western. I disconnected my batteries last spring. I reconnected and have 36Volts but my key circuit and volt meter don't work. I found two wires disconnected, one is for the reverse horn and the other I have no idea. The lights and horn work but no power to the motor. Need to know how the switch is wired to the power solenoid. There are 2 solenoids, one for the motor drive and I'm not sure what the other is for.
