Last night on the ride home, the speedometer was reading twice the speed I was going. When stopped, it went to zero, but at 50 mph, it read 100 mph. I think I know how to remove the center console so I can look at the back side of the speedometer. Any suggestions ????? 2003 Road King Classic

Sounds like the speedometer is faulty. If the speed sensor were the problem, the odometer would not work correctly, the transmission would not shift correctly, and the check engine light would be on.

sounds like speedometer cable is gone or the gears between the cable and transmission which makes the reduction for sppedometer if no cable on that year they have a sensor

I would suspect you have a faulty electronic speedo head, have the cluster removed and have it sent out for repair of the problem. There is no at home repair procedure for this problem, it takes special equip to repair the speedo.

Have the dealership reprogram the computer,it has lost it` s memory from disconnecting the battery.

Sounds like the instrument cluster has a internal failure. The only way to repair it is to replace the cluster.

replace your fuel filter

The speedometer in newer cars are electronic, so check your speed sensor.

I had a car that did this to me. It started happening last year so I took it in and they were baffled. Lesson learned never take a car to a big chain store for a difficult diagnosis.They just told me to let my car warm up for 5 minutes and it would be fine. If I let it warm up it was good. This winter it started doing it again but it would do it all the time even after I let it warm up. I never bothered bringing it in again because it was dieing. If you are truly concerned take it into a mechanic ( a good one) and have them diagnose it. Your spedometer cable could just be wearing out.

I took it in for repairs.
