Ok, I have a FD Hinson LS swap car and I am having major issues with my speedometer. I connected my battery one day and the speedo needle went all the way to past 180 and just stayed there. I recently did some work on my gauges like painting my bezels and like any other idiot, I just set the needle back to zero. After driving it for a while, it was working pretty normal again until the other day just cruising through a parking lot it became very sporadic and the needle would jump to 30 and 40 mph. Has this happened to anyone or does anyone have some recommendations as to how to fix this???? Thanks for even reading this.

 

So you do have your Dakota digital dialed in correctly?

I don't believe it's the lower limit that you set on these needle motors, but the upper limits. At full swing up, the needle will fall at some point well off each guage marking. You mark that with a pencil and reset your needles to swing back to that exact spot. The lower stop pin limits aren't the motors lowest swing.

You need another gauge set for reference, I think.
