SYMPTOM PROBLEM: REMEDY
INTERMITTENT MOVEMENT OCCURS WHEN
ACTIVATING A FUNCTION
9 volt battery is dead: Replace battery.
Antenna obstructed: Remove any vertical metal ob-
structions within two feet of the antenna.
Excess antenna cable is coiled : Rearrange an-
tenna cable to avoid coils.
Short wire connection on receiver antenna cable
connector : Be certain there is nothing touching the
bare portion of wires at the antenna connection.
UNIT DOES NOT FUNCTION Fuse is blown: Check the fuse and replace. Maxi-
mum 12 to 15 amp fuse in the receiver. If fuses are
blowing, there is another problem with the unit.
Wire is shorting: Look for dead shorts in wiring and
connections or run a new cable from the outputs of
the receiver to the solenoids direct and then try the
unit.
Solenoids on spool valve malfunctioning: Check
solenoids on valve for proper valve switching.
NOTE: Since the solenoid valves are hydraulically pi-
lot operated, hydraulic pressure must be coming to
the hydraulic valve before the solenoids can operate
the valve.
Improper grounds: Check diodes in ground circuit
for failure. Replace diode if required. Check ground
wires for tight connections.
UNIT FAILS COMPLETELY OR ONE OR TWO
OUTPUTS ARE NOT WORKING.
Power relay does not engage: See procedure for
resetting address code on Page 4-8.
ONE FUNCTION DOES NOT OPERATE The orange connector pin does not match the
Output Status Indicator LED: There should be 12
or 24 volts DC to that output, depending on the
power supplied from the vehicle. If power is going to
the output, then the wiring and hydraulic system
should be checked.
Appropriate Output Status Indicator LED is
turned on and there is no power to the orange
connector pin: Consult the factory.
