Tacho problems.

[Mitsi-undai]

Just a quick question.
What would make a tacho not work on idel, then out of the blue, while under ecceleration, jump to life for a second or 2, then of again? Drive for a bit, then on for 2 seconds and then of, then nothing at all?

Minets go buy and same thing happens. Please help

Have you checked all of the connections?

if it is in the cluster it could be a loose screw behind the cluster/tacho.

I'm assuming you have a 4G63 of some sort (J or Aspec)?
In my A spec VR4, I had a similar problem a while ago, ended up being the electronic Module that sits near the coil packs, I believe this is where the signal comes from. If yours is not a physical problem with the gauge, it could well be a similar issue. Good Luck.

OK. Yesterday I installed a factory dash/cluster to my Hyundai Lantra. My car didn't have this, so I wanted it to work so I could have a tacho dash. Befor installation, I took out the tacho to check for loose wires and such.

Everything looked good except for a little corrosion on some of the printed circettry. Reinstall tacho screws tight and back into my car. Hopfully this rules out loose screws, could still be a loose wire on that tacho module thingy???

As for the signel being faulty, my Apexi SAFC rev counter still works so I think I can asume that the signel is fine. At least to my retarded way of thinking anyway.
It is probably that tacho module thingy, I think maby I have bought a dud. Thanks for the replys guys.
