 WARNING 

Be sure the starter switch is in the OFF position to prevent electrical shock.

Remove the cable connecting the magnetic switch to the starter solenoid from the magnetic switch terminal.

Connect the leads of the digital multimeter, Part Number 3377161, to the two large-switch terminals.

Set the multimeter to measure resistance (ohms).

With the starter switch off, the multimeter must indicate resistance at infinity, open circuit.

Turn the starter switch to the START position.

The multimeter must indicate zero resistance, closed circuit.
