A16.0 Troubleshooting the Optional Stereo System (J-335 and J-345 only)
The optional stereo system provides a marine AM/FM/CD stereo receiver with two “pop-up” speaker
towers for superior sound quality. If the stereo deck does not turn on, refer to the following test proce-
dure.
A. Testing the Power Supply
1. Check for 240 VAC from the
TB1 terminal block to the
stereo power supply by
measuring across test points
18 and 19 as shown.
2. Check the inline fuses at the
back of the stereo deck for
continuity. The fuse in the red
wire is an 8 amp fuse that
supplies power to the deck.
The fuse on the yellow wire is
a 0.5 amp fuse that supplies
power for the deck’s memory
circuit.
3. Test the mating spade connectors (while connected) between the stereo power supply and the
deck for 12-15 volts DC. If voltage is unstable ( uctuating) or inadequate, replace the power
supply.
4. If the power supply and the fuses all test properly in steps 1-3, and the deck does not turn on,
replace the deck. If the deck does turn on but is malfunctioning, replace the deck.
B. Testing the Wireless Remote Control (Purchased Separately)
1. Power up the spa.
2. Point the wireless remote at the speakers and try to activate the stereo. Do the infra-red (IR)
LED’s (lights) on the speakers icker? If so, proceed to step 3, if not, try another wireless remote.
The rst remote may be defective or have a dead battery.
3. Unplug the IR Remote Interface from the stereo deck and try to activate the stereo system. Does
it work? If so, replace the module, if not, replace the stereo deck.
