86 Aspencade stereo will not tune

Postby alanc1100 » Mon Jan 31, 2011 5:46 am



Hello all, I have recently acquired an 86 Aspencade and have been going through it thoroughly. I have several issues, but the hardest to solve (for me) is the stereo will not tune. The stereo comes on, volume will adjust, but the station will not adjust. My first assumption is that the tuning selector on the left handlebar is not working. But, the clock also will not adjust, only blinks. If the fuse to the clock was blown, the clock would show no indication. When I unlocked and removed the stereo from the slideout, I noticed the fairing had a small crack on the right side in the upper right hand corner of the stereo opening. I had never noticed it before. I have had the fairing off, replaced fork seals, thermostat, freed up the choke cable (I know, should have replaced it, but I am cheap and have too much left to spend money on :) ) replaced air filter, oil filter, new oil, new fuel lines and filter, new silica-free antifreeze (which is still leaking and can't seem to find the source). Geez...and that is just what I have done so far. I still have to replace the front tire, brake pads, maybe rotors (balking at the price tag right now!) and timing belts (they look new, little to no wear). The trunk rack has caused cracking in the plastic around the mounts and I have a crack in the right aft corner of the RH saddlebag. Glad I chose to repaint it. Now it gives me an excuse to buy a plastic welder. Gotta fix those cracks before putting up $$ for a new paint job!!! Sorry to ramble, but I just had to tell what I have been going through. All that and I haven't even gotten to ride it yet!!! In any case, if anyone has any thoughts or ideas on the stereo tuning issue, I would really appreciate your input.

I can't make a comment on the stereo, as I know nothing about the 1200 stereos...but I can point you to people who can: Sierra MC. They are great, friendly, competent people who will be able to help you out.

Check the attached pix.Is this what you have?The yel/red is the voltage feed from the radio.The others feed this voltage back to operate each function.Check with a DVM only.Voltages may be only 5 volt.

Thanks, Virginmobile, for the advice and the diagram. The next chance I get, I will check those wires. Thanks again...Al

The channel control by the left hand grip controls the station selection up and down. It's basicly a momentary switch. That said it gets full of gunk and crud over the years and the contacts inside quite making good contact. You can try spraying electrical contact cleaner inside while working the switch. This will sometimes clean the contacts enough to work. Didn't work on mine I had to take it apart to clean it. Its a sealed unit. But here is how. On the back of the switch housing you will see a little seam. Take a drimmel or fine cutting tool and cut all the way around. When you remove the back you will see how the insides work and how to take it aprt a little further. You will see where the switch makes contact and all the old grease and dirt inside. Clean this crud off all the contacts and give it a try. You should be back in business. Now since you did a nice clean job of removing the the back side it's time to put it back together. Get a small can of ABS cement from the local hardware store. Like all the plastic on the wings its ABS plastic. Use a small amount of cement around the seam and seal it back together. Then when it sets you can also fill in any little spots. I have used this method and a mold or two to repair or make parts. But thats another story. I will post a picture of the switch later. I am off for a MC ride. East Coast and mid west eat your heart out..... :twisted:
I had a great ride and coffee with an old friend.
Here is a photo of the cut line for cleaning out the contacts for the raido station control. I have not finished it off yet. Looks bad in the photo, but you have to be looking for it to notice.
Enjoy the ride. They are all good, just some better than others.

Yes,this is a good fix.I've found switch contact problems on all my bikes(radio,cb,horn,starter).Use a dielectric grease on re-assembly.I have a car with a intermittent Transmission selector switch.Dealer wanted $280 to replace it.32000 miles and 4 years old.I removed the switch,cracked it apart,cleaned all the copper contacts,then(not EPA approved of course)coated the shinny copper with mercury.The contact surface will never corrode or arc out again.JB Welded together,Good to go. Cost me $3 for the glue and a old thermostat.

Before you tear the switch apart,you could unplug it,turn on the radio,short the white/blue and the yellow/red wire together to see if this operates the radio and verify the switch is suspect bad.

Thanks for all of the inputs guys. I could not get it working by checking the wiring. I gave in and bought another tuning switch/ harness. It was used, but it worked. The stereo tuned immediately and the clock allowed me to adjust the time. I am going to open up the old one and see if I can clean it up and fix it. Never know when you might need another one...
