radiated noise from wire
harness or motors
5.5
Transmitter 12-volt
battery is low
5.6
Out of 25 foot range
5.7
Interference
5.8
Component of
receiver damaged or
defective
5.9
Other equipment
installed in vehicle
causing voltage drop
when initially turning on
5.2a
Disconnect door and / or ramp motor and
recheck range.
5.2b
If range is ok, then ‘electrical noise’ from
motors is causing interference with RF signal.
5.2c
Move receiver and antenna a minimum of 6
feet from the motors.
5.2d
If moving receiver 6 feet does not improve,
an external antenna may be required to boost
signal.
5.3a
Disconnect receiver logic power input from
main wire harness.
5.3b
Run new wire from vehicle battery to red
wire.
5.4a
Disconnect receiver logic ground input from
main wire harness.
5.4b
Remove black wire on receiver from wire
harness and install on the vehicle frame for a new
chassis ground or vehicle battery.
5.4c
Remove any paint or residue from metal, use
an external tooth star washer and tighten new
chassis ground terminal securely to vehicle frame.
5.5
Replace battery if voltage is 11.5 volts or
below.
5.6
Move closer to the vehicle.
5.7a
Electromagnetic interference (EMI) caused
by any radio frequency (RF) nearby, motors,
welding equipment, relays, etc. May be in close
proximity to receiver / transmitter.
5.7b
Move closer to antenna or move vehicle out
of range of EMI caused by radio frequency,
welding equipment, as this is a temporary
problem.
5.7c
If EMI is caused by relays, door motors or
lift motors then the receiver must be moved or
shielded or the EMI noise diverted to ground. Call
the factory for details.
5.8
Send back to factory for repair or
replacement.
5.9
Remove all other equipment from logic
ground and power.
