2001 GoldWing 1800 Radio not Working

[Orig_Fantom]

I had my seat off and top fairing off to get to my radio to replace my led lights on the radio that burned out. I also had a battery going bad as well. I replaced with a new battery and then notice that my radio was not working. I replaced ALL the fuses (including the 100 amp and 70 amp fuse) and even disconnected the radio and re-plugged in. Still no radio would turn on as well as CD, CB, WB, and Intercom. Horn and bright lights work. I disconnected everything; the CB connection under the seat; the MP3 player (GROM) that plugs into the CD connector under the seat; the voltmeter that plugs into the turn signal housing top right; the cigarette lighter in left fairing pocket; the USB connector also in left fairing pocket; and the battery charger plugs. re-seated just the radio connections and still no radio response. Was on phone with Honda tech and they had no idea, just told me to take it to a honda shop. It been at the shop for over a week and still no luck. A new left handle bar control switch was installed, still no luck. My radio was put into a 2005 Goldwing and it works perfectly well on that bike, so the radio is not the issue. The radio from the '05 Goldwing was put into my bike, same results - no response. Honda dealership can not find any wires or other components that is cause this issue. Has anyone ever had this issue and found a resolution? I'm thinking I'm over looking something as well as the dealership.

Would it be wrong to assume the power and ground to the unit was tested?

[Orig_Fantom]

Yes those were checked at dealership.

The one time I had a similar issue on my 2003, it was because I tried to use the A.SEL function while using my BikeMP3 player. That confused the on-board computer and I lost the AM-FM-CB and everything else except intercom.

Disconnecting the battery over night and reconnecting took care of the issue. I suppose leaving the battery disconnected for 30 minutes or so may have taken care of it but leaving it disconnected overnight as I slept was my best option at the time.

Check your connectors where you unplugged them and see if there isn't any bent pins.

[Orig_Fantom]

Thanks all that have responded so far. Pins have been checked and rechecked by three technicians, no bent ones. Battery has been off for over two days and still the same issue. I'm also not using a BikeMP3... I have a GROM - Honda Acura 03+ USB Android iPod Bluetooth AUX adapter ((HON1)) that was installed and it was working just fine for over three weeks before I replace battery/fuses/etc. The only plugs for the radio are the two that plug in underneath the radio and the one on the side for the antenna. Dealership is having issues on finding this one, they have been swaping out parts between my Goldwing and another one that is their. Any parts from the other Wing (which has everything working correctly, no issues) put into my Bike has no affect, yet my parts can go over to other Wing and works their. Tech is thinking on opening up the wire harness next to see if a wire was pinched or damged. Ground cable under gas tank is also ok and bolted down.

That's what his multi-meter is for.

I was not trying to suggest your failure was the same as mine, just letting you know what I experienced when I lost all audio systems and how it was rectified. Good lock with your search and subsequent repair.

[wing rider 2012]

Is it just the the radio and related components that are not working? Does all your lights work, turn signal and instruments panel ect.?

[Orig_Fantom]

Yes... Lights, horn, high beam on that switch (left handel) works. The switch was now replaced and still same issues. The console display shows the Goldwing log during startup and I can activate and see: temperature, clock settings, rear suspension settings, and odometer / trip readings. All functions that are available on the radio unit (AM/FM, CB, CD, WB, AUX, Intercom) are not responding and show active indication in the display. Also no radio output from headset or speakers.

My newly acquired 2004 GL1800 with EZS Monroe Sidecar has a similar fault. I brought it home to England from Ireland on the 3rd May 2018 and the radio and CD player worked fine and displayed properly for over 200 miles. After some intense maintenance over the past two weeks I reassembled it all yesterday and everything works except the radio / CD display.

The Volume button on the radio does not now work and I cannot turn off the audio with it. All other functions still operate correctly from the handlebar switches and the volume, programme, track, station all work.

The Mode knob functions correctly but I have to guess at the settings because there is no display.

The display panel works fine during start-up, the welcome screen scrolls properly and the bottom line of information - miles, Trip etc all show, I programmed my name into the system and that is stored and is remembered when the battery is disconnected.

I've pulled fuses, removed the battery, left it disconnected for hours, re-checked all the connections that I disturbed and still no display for the audio.
Has anyone experienced this before - the part number is 39110-MCA-6010 No. RM-G45EA and has a big E on the label.

Where can I get the unit serviced?

[Orig_Fantom]

Thegonands ..take bike to Honda dealership, they can swap out parts from other Goldwings to help identify cause.

[Orig_Fantom]

OK latest news... pins 33 and 34 checked out ok (connector "A" for the radio)...no bent pins in the two radio connectors. The white housing that has the grey 22 pin connector inside the left fairing pocket is also ok, no corrosion and no bent or broken wires. The connector behind the gauges are also ok and no loose connections. Dealership is calling Honda support for further analysis (one recommendation was to replace the whole wire harness). Also the units below the radio as you head to replace air filter is going to be checked as well.

[Orig_Fantom]

OK...after two weeks of the bike in the dealership shop, half torn apart and a threat to start replacing wiring harness, the culprit has been identified. My "J&M CB Volume, Mic On/Off Passenger Control" was the issue, after the positive wire was taken off the fuse box terminals, the radio functionality all started to work. Radio, CB, CD (GROM MP3 player), WM, AUX, and Intercom fully functional and displays in the LCD console. I was about to send the J&M unit back when it dawned on me, I did not ground the unit properly. In my diligence of having wires neatly tucked away and out of sight, I forgot that I moved the ground wire from the J&M device from the frame to the fuse box what I thought was a negative terminal. I re-positioned the ground wire, re-attached the positive wire and re-tested the switch. Switch works and so does the radio, everything back to fully functional bike. So..my what I assumed was a proper ground ended up costing me $350.00 ($150.00 for radio diagnostic + $200.00 to dismantle and re-assemble bike), a costly lesson not to be repeated. Thanks all to those that replied.

I'm glad you found the problem, although it was an expensive mistake we live and learn.
