Question about Harley Davidson 426290 AM/FM Radio

1 Answer

2004 Harley UC Radio - no sound on Left side

Only sound I can get from left front and rear speakers is static unless I turn volume up really loud then I can hear garbled sound. Right speakers sound fine. Headset sounds fine as well - both right and left side.

Thought it was a loose connection but I have removed fairing, tank, ignition switch and speaker switch panel and have not found any loose connections. I'm beginning to think problem is within the radio rather than in the connectors. Radio is hard to bench test because it has large specialized modular plugs.

I suspect this radio outputs sound to each separate destination ( front speakers only, front and rear spkr combo, or earphones only) rather than having one audio output which is externally switched. If this is true then problem probably lies within the radio.

    Definately not antenna. As I said problem only affected left side speakers, not ephones or right side spkrs. Anyway, problem solved. For $135 I sent it off and exchanged it for a rebuilt one which works fine. Seemed like a lot till you learn HD radios go for about a grand.

Left speaker you can barely hear


Swap the speaker outputs from left to right and see if the defect moves to the other side. If it does, the radio will need to be repaired. If it stays on the left side...bad speaker.

Radio working just fine But no sound coming from speakers


if the radio still has power the audio amplifier ic in your radio has failed.
take your radio to an electronics repair shop or, replace the radio; this not something you can fix unless you know how to use an oscilloscope.

Harmon/Karden 2006 Radio/CB/CD Passanger control does not work


The passenger controls on the rear speakers are pretty easy to diagnose.  The wire for Volume up is Pink/white, the volume down is gray/white.  If the Pink/white wire is shorted to ground somewhere, then as soon as you turn on the radio, it will be like having the volume selector pushed up, and it makes sense how you describe it goes to mute and then returns to full volume as soon as you let go.   You don't say what model it is (I doubt it's a Road Glide, gotta be an Ultra), so it's not too hard to get at.  Pull the outer fairing and look on the back of the HK Radio.  There are 2 big connectors, when looking from the front you want the connector on the right.  Pin 23 is down volume, pin 34 is up volume for the rear controls ONLY.  So I would check the continuity to ground at pin 34 first, in other words pull the connector off the back of the radio, take a test lead and hook one end to +12v. Touch the tip to any grounded metal and it should light.  Now touch the tip to pin 34 on the harness side of the connector.  If the test light lights up, you have a short to ground on the pink/white wire.  Now go to the right rear speaker on the tour-pak and disconnect the 6 pin connector and try the test again.  The pink/white goes from pin 34 on the radio and runs through the harness to the passenger controls and nowhere else.  It shouldn't be grounded anywhere.  Let me know what you find out.
