Glow Relay - Toro 04384 Service Manual

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
fuse block (Fig. 27) and is connected to the wire harness
with a four (4) wire connector (Fig. 28).
Relay Testing
1. Disconnect wire harness connector from glow relay.
2. To allow easier access to relay terminals, either loos-
en fasteners that secure relay to bracket or remove relay
from bracket.
3. Verify coil resistance between terminals 86 and 85
with a multimeter (ohms setting). Resistance should be
from 41 to 51 ohms.
4. Connect multimeter (ohms setting) leads to relay ter-
minals 30 and 87. Ground terminal 86 and apply +12
VDC to terminal 85. The relay should make and break
continuity between terminals 30 and 87 as 12 VDC is ap-
plied and removed from terminal 85.
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.
