My RPM gauge works fine but sometimes it just stops..
and just sits doing nothing..
whats up with that?

take out the instrument panel

look for corrosion on the plug connectors

or on the printed circuit on the panel itself

I have a cluster from a TM to can have for a small donation. you can take the tacho out of it and fit it to your TP one if you got the patience.

ill try find a way to take it off :)
thankyou ladds :)

I've noticed it only drops out when high revs or i go over a bump..
anything maybe?

Loose contention or broken track on the cluster :) Not sure but if it a broken track on the cluster might new a whole new cluster :)

My TP dash had the same problem

I think the taco (RPM) runs off one of the wires

running to the dissy pin plug in (there are four wires)

pop the dissy connector off and clean the contacts there

or look for a broken wire/corrosion
