Receiver Power Check
Remove the cover to the receiver and locate the power indicator lamp (11). Place the manual / remote switch in the
“remote” position and turn the engine keyswitch to the “run” position (do not start the engine!). The power indicator
lamp (11) should come on. If it does not come on, check the 7.5 amp fuse found in the upper right hand corner of the
receiver box. If the fuse is good, check for wiring continuity from the manual / remote switch to the radio receiver. 12
volts DC should be available at the power terminal inside the receiver enclosure.
Receiver / Transmitter Communication Check
If the power indicator lamp (11) is on, then proceed to test the remote functions. Begin by pressing and holding the
ENG button on the transmitter. The RF indicator lamp (10) should come on. When the RF indicator lamp (10) comes
on, that is proof that the transmitter is sending a signal and the receiver is receiving the signal. This is true for any of
the functions available on the transmitter. If the RF indicator lamp fails to come on, remove the power supply to the
receiver and wait for 30 seconds. Connect the power to the receiver and retest. If the RF indicator lamp (10) still does
not come on, check the antenna connections and cable.
