ELECTRICAL

How It Works

The glow pug switch is manually depressed and held in
place for 10 seconds. This activates the relay that closes
the circuit which sends current to the glow plugs.

Testing

Only terminals 1 and 2 are used in this application. The
switch can be tested with an ohmmeter. There should
be no continuity between terminals 1 and 2. When
the switch is depressed, there is continuity between
terminals 1 and 2 (Fig. 676).

hours.
