I have an 07 heritage and from time to time the speedo quits. the bike will keep running and its about 50/50 that it will die when I come to a stop and let the throttle drip to Idle. It always starts right back up. some times it will start to register as I ride and some times it won't. It will start to work if I turn the ignition off for a few and restart it. When the speedo quits the odometer stops registering and the turn signal auto-cancel stops working. Everything else works normally. Ideas? suggestions?

 

I'd say it was the vehicle speed sensor (VSS.)

 

Definitely. Been through 2 of them on my 09 Fatboy. Located on the top rear of the transmission.

 

It's a cheap part but a royal PITA to get to.

 

check the ignition switch , it went out on my 2000 heritage ..... same problem , speed o lights flashing motor wanting to die .

If that is it the HD dealer will want 120 clams for it !! I went with Dennis Kirk .

First thing to do is clean the battery connections and the ground

Second is VSS. I've been through 3 of them on my old softail. (2005) If I remember right they're like 75 bucks from harley. Vehicle Speed Sensor. On top of the tranny

Third thing to check is the ignition switch.

Good luck

 

If the auto-shutoff on the turn signals isn't working as he says, It's the VSS guaranteed.

 

I got pissed off after two of the Harley ones, then I ordered an off brand that has worked like a charm.

Biggest pain was getting to the connector.

 

What off brand did you get? I could never find one when mine went out at 4k miles. I didn't want a HD one to go back in it.

Thunderheart. Didn't have another problem after that. I think I had to solder wires, but no big deal.
