Default Aftermarket Speedometer not working

Hello,
recently purchased a Dakota Digital MCL-5100 for my 04 Softail. connected it up per the instructions and all works (turn signals, oil, high beams, neutral) except for the the speedometer. Before i go out and purchase a new VSS (speed sensor) was wondering if anyone has suggestion on how i should troubleshoot it beforehand?

what i did so far is turned the ignition to ON and tested the signal wire (green/white coming out of the ECU where i teed up my wire for the speedo) and i am getting 1.5V. (appears low to me, as i think it should be near 4-5V DC). any other testing i should do with my multiumeter to confirm it's a defective VSS?

(oh and yeah, i read all the posts on cleaning the end of the VSS magnet to remove debris.... didn't work)

thank you!

Did your old speedometer work? If not, would be looking at the speed sensor.

  • When I purchased the motorcycle there was no Speedo. Before changing the speed sensor I was wondering what tests with my multimeter.
  • I disconnected the original speed sensor and tried to get a reading at the plug when the ignition is set to ON but no success. so wondering if my problem is more than a speed sensor.
