Bought a set for my 2001 FLHT. The problem is I keep getting bleedover from the tach signal into the speedometer. If I accelerate over 1500RPM, the speedo shows a reading close to the RPM speed. After several calls to Dakota, and following all their suggestions, still happens.

I have tried different positive and negative leads, re-routed wires, even installed an inline capacitor to increase the resistance. For those familiar, mine is a 3 wire VSS. All three wires are connected properly according to Dakota, and it will register speed when I ride, albeit wrong! I'm hoping someone else here has possibly run into this. Everything else works sweet, and I can still ride it...but the accuracy of the speedo is gone.

 

Bump.

No one else has had this problem? Tried all the suggestions from Dakota Digital, may have actually made it a little worse. Perhaps a bad gauge? Anyone have it fail...how do you know?

Getting fed up screwing around with this.

 

Dakota was really helpful when I put their stuff into my fairing... I'd be persistent with them. Sorry, I'm probably stating the obvious.

 

No problem....they have been great. I lost count how many times I've talked to them. They are pretty certain it's picking up something through the speed sensor wire.

 

Evidentally, I'm the only one here who has run into this. Tonight, I discovered that if I connect the gauge directly to the battery, it works. So...anyone have a suggestion as to how to hook this up to a positive connection behind the fairing that doesn't involve the ignition?

 

If all else fails, you could use a relay. Run a wire directly from the battery up to the fairing, and connect it to the relay, then out of the relay to the speedo...use the "hot" wire that was powering the speedo to energize the relay. That should isolate the power from the ignition switch, only have power to the speedometer "on" when the ignition is on, and still give you the "clean power" directly from the battery.

 

Hmmm....sounds like it will work. My only other option was to use a toggle switch to power up the speedo from the battery. Any specific type of relay? Haven't had any experience with them.....
