A16 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 procedure.
A.
Testing the Power Supply
1. Check for 240 VAC from the
TB1 terminal block to the ste-
reo 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 sup-
plies power for the deck’s memo-
r
y 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
(fluctuating) 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 flicker? If so, proceed to step 3, if not, try another wireless remote. The first 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.
