58A16.0 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” speakertowers for superior sound quality. If the stereo deck does not turn on, refer to the following test proce-dure.A. Testing the Power Supply1. Check for 240 VAC from theTB1 terminal block to thestereo power supply bymeasuring across test points18 and 19 as shown.2. Check the inline fuses at theback of the stereo deck forcontinuity. The fuse in the redwire is an 8 amp fuse thatsupplies power to the deck.The fuse on the yellow wire isa 0.5 amp fuse that suppliespower for the deck’s memorycircuit.3. Test the mating spade connectors (while connected) between the stereo power supply and thedeck for 12-15 volts DC. If voltage is unstable (fl uctuating) or inadequate, replace the powersupply.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 fi 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. Doesit work? If so, replace the module, if not, replace the stereo deck.POWERSUPPLYREMOTEINTERFACE STEREODECK15VDC(SpadeConn.)ANTENNAMAIN LOAD BOXTERMINAL BLOCKTB1240 VACIR SENSORSSPEAKERS18 19Fuses
