1992 Heritage softail. Turn signals work when sitting still but when I get going they dont. Also the speedo is erratic, jumps around from 20 to 40 mph. I was thinking speedo sensor and/or turn signal module. I'm not sure if this model even has the TCM. Hope someone can help! I need to know my speed and for safety would like folks to know when I'm turning. Thanks!

 

You have the mechanical speedometer so unless there is a connection between the Speedometer and the TURN SIGNAL CANCELLER PN: 68537-89G I cannot see a connection. But I do not have the Wiring Diagrams for that year available to me at this time so I cannot be certain. I would look at the Speedometer cable PN: 67079-86A for the speedo issues and the Turn Signal Canceller for the turn signal issues. Maybe check the connector going to it to ensure that it is fully seated.

 

Hey thanks for the reply! I'll start with the cable. What about the speedo sensor?

 

Possible as well, that would be PN: 67125-86A. Seen more cable failures than drive unit failures though.
