Electrical System (Rev. C)
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.
