Glow Relay - Toro Greensmaster 3250-D 04383 Service Manual

Glow Relay

When energized, the glow relay allows electrical current
to the engine glow plugs.
Two styles of glow relays have been used on the
Greensmaster 3250--D. On machines with serial num-
ber below 250000000, two of the four relay connections
are secured with screws (Fig. 33). Machines with serial
number above 250000000 use relays that are con-
nected to the wire harness with a four wire connector
(Fig. 34).
1. Verify coil resistance between terminals 86 and 85
with a multimeter (ohms setting). Resistance should be
from 41 to 51 ohms.
2. Connect multimeter (ohms setting) leads to relay
terminals 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.
3. Disconnect voltage and multimeter leads from relay
terminals.
