Re: Starter wiring issues...

Simple explanation.
You turn the key to the start position and 12v is sent to the solenoid.
Two things happen.
The starter spins and cranks over the motor.
Power is supplied to the coil wire thru a connection in the solenoid. Usually a yellow wire.
Motor starts.
You release the key to the run position.
Starter stops.
Yellow wire gets no power. No connection in the solenoid now.
Power is supplied thru the resistor wire to the coil. Usually 7 to 9 volts.
To trouble shoot the system.
Key in start position, starter spinning you should have 12v to the coil.
Key in run position, you should have 7 to 9 v at the coil.
