Caution: Be sure the starting motor switch is in the “ OFF” position to prevent electrical shock and personal injury.
Remove the wire connecting the starting motor switch to the magnetic switch (marked “ S ” or “ Start”) from the
starting motor switch terminal.
Connect the positive lead of Part No. 3376898 Digital Multimeter or equivalent to the starting motor switch terminal and the negative lead to a chassis or engine ground location.
NOTE: With the starting motor switch in the “OFF” position, there must not be voltage at the starting motor switch terminal. Ifthe meter indicates voltage, the starting motor switch is malfunctioning and must be replaced.
Turn the starting motor switch to the “ START” position.
The multimeter must indicate system voltage.
If there is not voltage:
– Turn the starting motor switch to the ‘ ‘OFF” position.
– Connect the multimeter positive lead to the starting motor switch terminal having a wire connecting the
starting motor switch to the starting motor solenoid “ B” terminal.
If the meter indicates system voltage at the starting motor switch input terminal, the starting motor switch is defective and must be replaced.
If the meter indicates no voltage, the switch is not the cause of the complaint.
Check the wiring from the starting switch to the starting motor solenoid “ B” terminal and from the starting motor
solenoid to the battery for broken or damaged wires.
