controller detects excessive electrical
current to the motor.
1. The spreader controller does not
detect the motor feedback voltage.
1. One of two outputs are not providing
power to motor.
1. The spreader controller or the sprayer
controller cannot detect a connection
to the motor.
1. A main fuse is open.
2. Loose electrical connections.
3. Open ground electrical connection.
4. The controller module is damaged.
1. The electrical connections are
corroded, loose, or faulty.

for obstructions that may add an
excessive load to the impeller motor.
Spreader or sprayer—check the
electrical circuits to the motor for a
short circuit. Tap the impeller control
switch or the sprayer-pump switch to
start the spreader or sprayer motor.
1. Check that pin 18 (M
OTOR
and locked in the controller connector.
1. Check that pin 6 (M
OTOR
pin 8 (M O 2) are seated and
OTOR UT
locked in the controller connector.
1. Shut off the impeller motor or spray
pump motor, and check electrical
connections to the motor.
1. Replace the open fuse.
2. Check electrical connections at the
accessory power connector and
battery ring terminals and ensure both
have power.
3. Check the ground circuit to the
controller.
4. Replace controller module.
1. Check the electrical connections for
contact. Clean connector terminals
thoroughly with electrical-contact
cleaner, apply dielectric grease, and
connect the terminals.
1. Ensure that the harness connector is
seated and latched securely to the
rocker switch.
2. Check for incorrect pin positions.
1. Shut off the impeller motor and run the
engine to until the battery is charged.
2. Run the machine at a higher engine
speed.
