There was no response when I turned the key to start position yesterday, like there was no battery. But, when I jumped the post on the solenoid, the starter spun the motor just fine. I have not found the schematic diagram, but suspect the switch itself, or a relay. I just tested for 12 volts at the solenoid, from the switch, and it was not there in the start position. I would think the start position of the switch would close the circuit between the red and white wires, since the one going to the solenoid is white. But, it looks like there is a relay between the switch and solenoid. Any ideas? Thanks
