2001 Road Glide TC88
Cruising home from Reno tonite, about 80MPH The speedo needle started going crazy would go down to Zero and then swing back and forth between my spped and zero. At one point it stayed on zero for about 10 minutes or so. Also at the same time this was happening the volume on the stereo would get super low when it was happeningand would come back on when the speedo started working. Also the odometer quit registering miles while it was going crazy. but when the speedo was working the odometer was fine. The back lighting and the numeric odometer display seem to work just fine.

 

Wasresearching a little and I just cleaned the Speed sensor and will test it out tomorrow. it had a bunch of nasty stuff on it, wipped it all off and reinstalled. Will ride it tomorrow.

Update: Rode to work this morning and had no issues. But its only a 15 minute ride. I will ride for a while after work to see if cleaning the speed sensor fixed it!

 

If it happens again, replace the sensor. Other telltale is blinker cancellation stops. Very common.
