GL1500 Radio Volume Muted

Post by JHGoose »



2000 GL1500 SE - Radio will become muted for no reason that can be ascertained. Mute switch is OK. Replaced the wiring harness side 18 pin radio connector. Fuse/relays down in front of left saddlebag OK. CB turned OFF. I believe that I have an intermittent open in one of the wires to the 18 pin connector but can't determine which one it is and am hoping and praying that someone has had the same problem and can identify the wire. Else I am in for a long troubleshooting session. Thanks to my hero that knows the answer to this one.

I've had similar experiences with my radio. I've managed to eliminate it by switchology.

What position do you normally have the Intercom Mute and AVC controls turned to? I keep the Intercom Mute fully clockwise and the AVC at fully clockwise.
No longer an issue.

When yours goes Mute, does Mute show up on the LCD? I've only seen the Mute indicator when the Mute button on the handlebar control was pushed.

If you are still have issues, you should probably contact Sierra Electronics.

Before you go down the wiring rabbit hole, make sure all the (maybe not so) obvious causes are dealt with. You already said the CB is off, that's one of the main causes (CB on, but volume all the way off, when it breaks squelch, it mutes the radio). The other is the intercom, which can do the same thing. So make sure the intercom is off and it still does this before tearing into wiring.

Wanted to post an update and maybe save some other folks the agony of chasing an intermittent fault. In chronological order here goes:

Some months ago I removed all the plastic to enable me to replace the air cleaner and the other two (2) filters (can't remember what they do but replaced anyway). I had to remove the radio mount w/radio to accomplish this task. Unfortunately, I did not realize that I had broken pin 18 on the radio side of the 18 pin connector. When I put all back together the radio would intermittently mute volume, would default to AM radio operation when turned off and lord only knows what other strange symptoms.

I could wiggle the wiring harness going to the 18 pin connector the radio would resume normal operation. Since I had broken the locking tab upon removal I replaced the radio 18 pin connector on the wiring harness side. I know better but did not look down into the radio side of the connector. I finally untapped the wire harness and was going to wiggle one wire at a time and finally looked down in the radio side of the connector and discovered that pin 18 (red/yellow wire) broken in the radio side of the connector (The "blade" or "male" pin).

I completed electronic tech school at Ft. Gordon, GA in 1972 but now shake too much to solder in a new connector on the radio circuit board.

I am sending the radio to Sierra electronics. They previously repaired a radio and a CB from my GL1200 some 20+ years ago. I am a repeat customer and very satisfied with their service to the motorcycle community.

Thank you for all that responded as this fault had me chasing my backside trying to troubleshoot.

Good work Goose. Glad you narrowed it down and then came back and let us know. It is highly appreciated when a fault is identified and reported back to the board.
