Fuel Pump Relay (Groundsmaster 3320)
The Groundsmaster 3320 uses a relay to energize the
fuel pump. The fuel pump relay is attached to the sup-
port bracket inside the right side frame near the fuel filter.

Testing
NOTE: Prior to taking small resistance readings with a
digital multimeter, short the meter test leads together.
The meter will display a small resistance value (usually
85
30
0.5
ohms or less). This resistance is due to the internal
resistance of the meter and test leads. Subtract this val-
ue from the measured value of the component you are
testing.

1.
Locate relay and disconnect the machine wire har-
ness connector from the relay.
2.
Using a multimeter (ohms setting), measure coil re-
sistance between terminals 85 and 86 (Fig. 37). Resist-
ance should be between 70 and 90 ohms.
3.
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.
4.
Disconnect voltage from terminal 85 and multimeter
lead from terminal 87.
5.
Connect multimeter (ohms setting) leads to relay ter-
minals 30 and 87A. Apply +12 VDC to terminal 85. The
relay should make and break continuity between termi-
nals 30 and 87A as +12 VDC is applied and removed
from terminal 85.
6.
Disconnect voltage and multimeter leads from the
relay terminals. Connect relay to machine wire harness.
