2002 Harley Davidson FLSTF Fat Boy speedometer not working @

Duplicate question already answered

Remove the speed sensor at the left rear of the trans housing and clean off any metal shavings on it. Shavings get caught on the magnet and won't let the sensor read properly.

Hi, Rhargett3 and the usual suspects are:
1. Contaminated or faulty speed sensor.
2. Faulty turn signal module.
3. Corroded, broken or loose connector pins/sockets in the wire harness between the speedometer and the ECM or TSSM and the sensor.
4. The speedometer unit has failed.
5. Speedometer instrument fuse has blown.

You're better of to simply purchase a new speedo. There are places that can replace the face in your speeometer but this work is expensive. The service is primarily for restoring antique speedometers. Just buy a new speedo.

Good Luck

There are places that can repair the speedometer but they're usually more expensive than just purchasing an new one. They specialze in repair of the older antique speedometers.
