Connect the leads of digital multimeter, Part No. 3377161,
or equivalent, to the two large switch terminals.
Set the multimeter to measure resistance (OHMS).
With the starting motor switch in the OFF position, the
multimeter must indicate resistance at infinity.
Turn the starting motor switch to the START position.
The multimeter must indicate zero or very little resistance.
If the multimeter indicates resistance at infinity with the
starting motor switch in the START position:
Turn the starting motor switch to the OFF position.
Set the multimeter scale to read DC voltage.
