Use a digital or analog voltmeter to check power and voltage!
Do NOT use a test light
Trouble Shooting Guide - 1000 Series Remote Control
1.0
No output from one or
more outputs on receiver
when transmitter buttons
are pressed
1.1
No signal from transmitter
1.2
One or more of the outputs
have failed.
1.3
Receiver outputs OK, but
relays or equipment do not
operate.
1.4
Fuse is blown.
1.5
Wire harness problem
1.1.1
Verify that transmitter is sending a signal and that
transmitter is coded correctly. See Symptom 3.
1.2.1
Open receiver and observe yellow LEDs. The output LED
should turn ON as long as relay is ON.
1.2.2
Press each transmitter button in sequence. Using a volt
meter, check each output. There should be +12V present
anytime the corresponding transmitter button is pressed. If no
outputs, call factory for RMA number.
1.3.1
Check wire and equipment for problem.
1.4.1
Check the fuse in fuse block. If fuse is blown, replace it.
1.5.1
Check input wire harness connections on J2-6 and J2-7. If
no voltage, correct wiring.
Symptom
Possible Cause
2.0
Receiver is ‘dead’.
Does not operate, no heart
beat LED.
2.1
Logic ground or power
connection to receiver has failed
2.2
Chassis ground connection has
failed
2.3
Receiver and / or
microprocessor has failed.
2.1.1
Check logic ground and logic power. Use a voltmeter
probe when checking voltage.
2.1.2
If either ground or power is not present, then locate failure
in wire harness and repair.
2.2.1
Check chassis ground connection, it should be clean and
tight, no paint on metal, an external tooth star washer should be
present, no rust or dirt in connection.
2.2.2
Chassis ground should be located on vehicle frame or
directly to battery.
2.31
Check yellow output LEDs. If they DO NOT flash each
time corresponding channel is activated, the receiver has failed.
Call factory to get RMA number.
2.3.2
Check heart beat LED. If it is not flashing, the
microprocessor has failed. Call factory to get RMA number.
Symptom
Possible Cause
Corrective Action
3.0
No signal (code) being
transmitted
3.1
Transmitter battery voltage
low
3.2
Transmitter code is incorrect
3.3
Not all buttons send a signal
when pressed.
3.1.1
Check battery voltage, should be 3.0 VDC. Replace
battery if voltage is 2.8 VDC or less. (Signal strength is
dependent upon battery voltage.) Transmitter LED does not turn
on if battery voltage is low.
3.2.1
If transmitter is sending a signal (LED turns ON) and no
signal is being received, re-enroll transmitter to receiver. If
unable to enroll transmitter, call factory for RMA number.
3.3.1
If a signal is not transmitted on all buttons, send back to
factory for repair or replacement.
