Glow Relay
When energized by the glow plug controller, the glow
relay allows electrical current to the engine glow plugs.
The glow relay is attached to a frame bracket near the
fuseblock(Fig.27)andisconnectedtothewireharness
with a four (4) wire connector (Fig. 28).
Relay Testing
1. Disconnect wire harness connector from glow relay.

3. Verify coil resistance between terminals 86 and 85
with a multimeter (ohms setting). Resistance should be
from 41 to 51 ohms.

5. When testing is complete, disconnect voltage and
multimeter leads from relay terminals.
6. Replace glow relay if testing determines that it is
faulty.
7. Connect wire harness connector to glow relay.
8. Secure glow relay to bracket.
