Radio controls stopped working!

[motorhead1977]

The volume and channel controls on my 09 GL1800 stopped working but only in the lower volume and down channel/CD functions! Happened suddenly. Everything was working fine but after stopping for a walk and cold drink when we started out again the malfunction began. Help! I never realized how much I used those controls until this happened. TIA for your help.

First thing to do is disconnect the negative terminal on your battery, then test out the battery and connections prior to reconnecting. Take your time and give it about five to fifteen minutes. Reconnect the negative terminal, ensuring both pos and neg are tight. Turn on your bike and see if your radio has reset. If not, then on to further diagnosis, but glitches like this are quite common on the GL1800, and a total reset by removing all power usually corrects them. Hope it works for you.

It is very possible that the switch quadrant on the left handle bar is just dirty. You could probably benefit by squirting some Electronic Contact cleaner into the quadrant and operating the switches multiple times. When you do this, make sure you cover anything on the bike that could be damaged by the solvent, paint, plastic and the like. Use an old sheet or large bath towel to cover things up.

Did the radio reset. No change. Still no down volume on the volume switch and no down channel/CD track at that switch. Going to try the contact cleaner tomorrow but since there wasn't any malfunction ever before the sudden failure I'm not very hopeful. Any additional suggestions may help. TIA.
