Glow Relay - Toro Reelmaster 2000-D Service Manual

Glow Relay

The glow relay is attached to the instrument panel.
When energized, the glow relay allows electrical current
to the glow plugs.
NOTE: Prior to taking small resistance readings with a
digital multi meter, short the meter test leads together.
The meter will display a small resistance value (usually
0.5 ohms or less). This resistance is due to the internal
resistance of the meter and test leads. Subtract this val-
ue from from the measured value of the component you
are testing.
NOTE: The glow relay may be manufactured by one of
two different manufacturers. Verify manufacturer name
and part number before performing the resistance
check on the relay coil.
1. Verify coil resistance between terminals 85 and 86
with a multimeter (ohms setting):
A. For the Tyco
(#VF7–41F11–S01), resistance should be approxi-
mately 72 ohms.
B. For the Hella Electronics relay (#87430B), resist-
ance should be approximately 100 ohms.
2. 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
applied and removed from terminal 85.
3. Disconnect voltage and leads from the relay termi-
nals.
