1500 electrical problem

Postby uttrainman » Thu Oct 24, 2013 5:18 pm



Returning from a 3300 mile trip, 100 miles from home, I lost my speedometer, cruise control and turn signal cancelling feature at the same time. Is there a connection between these three items? Do not have access to a wiring diagram to trace circuits. Is the speedometer mechanical or electrical (optical or magnetic)? Any suggestions on where I start troubleshooting? All fuses check good.

Your speedo cable has either come undone, broke or the gearbox at the wheel broke. Cruise control function is stopped when speedo stops,same with turn cancellation because the counter stops counting. Try examining at the wheel end first.

Reach up and unscrew the speedometer cable from the back of the speedometer, then spin the front wheel. If the end of the cable doesn't turn when the front wheel turns, then it's either the cable or the speedometer drive at the front wheel. If it does turn, the problem is in the speedometer housing itself.

Next unscrew the cable from the front wheel and again spin the front wheel, watching to see if the blade in the hub that actuates the cable turns. If it does, you have a broken cable. If not, it's a problem with the drive.

I just had my 95 dash out and on the workbench yesterday, there is a counter on the back of the speedo with an electrical plug, the speedo itself uses a magnet to move the MPH indicator of KPH if so. If the cable isn't turning no speedo, and I believe that counter is part of the TS canceling, it counts so many revolution such as something like 500 ft? Then it opens the TS circuit stopping the flash. I never really counted how far it takes to cancel the TS on my bike, but when I first bought it back in july the cable was undone down at the axle gearbox, the cable was also bone dry, I think the PO took it off because it squeaked, I cleaned the housing out with electrical cleaner and used Superlube synthetic grease on mine, other bikes I have used Lubriplate white grease.

If by chance you take the speedo out I suggest greasing the very end, try pushing some grease up into the housing with a q tip or something. Many people forget that part itself and the gearbox down at the axle need to be lubricated.

I had this exact problem a year avon and it turned out to be the plastic gear in the drive attached to the wheel. This seems to me to be the sacrificial part of the system.

WingAdmins trouble shooting will tell you where the problem is. It isn't electrical so you'll keep your hair.
