How It Works

The starter motor and solenoid work together to crank
the engine over. The solenoid works as an electric
switch that connects the battery with the starter motor.
When the ignition key is turned to the start position
battery voltage activates the solenoid that energizes the
starter motor and pushes the starter gear forward. The
starter gear meshes with the engine flywheel to crank
the engine.

Testing

1. Clean and inspect the battery cables and terminal
ends for damage.
2. Use a voltmeter to check the battery voltage at the
positive cable post on the starter solenoid.
• The voltage should not read less than 12 volts.
If 12 volts is not present, charge the battery and
inspect battery cable and connections.
3. If the voltage is good at the positive starter post then
proceed to the next step.
4. Turn the ignition key to the START position.
5. Use a voltmeter to check for 12 volts at the starter
solenoid blue wire terminal.
• If 12 volts is not present than test the start relay,
blue wire, battery cables and connections.
• If 12 volts is present then remove and replace
starter solenoid and starter motor.
