Re: Power Starter Wiring
To figure out which of the solenoid wires is your crank wire, take a resistance measurement from each of them to the shell. The solenoid terminal will show resistance and the other terminal will show open. If they're both open, you have a bad solenoid. You can also measure resistance of the motor power terminal to the shell and you should see resistance. In both cases, the resistance will be fairly low, though the motor resistance will be very low.
