R33 Tacho Question

[zero-R33-]

Hey guys,

The R33 I'm buying had its pre-purchase inspection and passed it with flying colours, other than a few minor things, eg parker globes. Anyways, I noticed that the rev tacho just jumped all over the place when actually driving as well as idol.

My mechanic seems to think it is something to do with the ignition while the guy im buying it off doesn't really know whats causing it.

Have any of you guys experianced/heard of this problem?

If so, what was causing it and how do I fix it?

Thank a lot.

so is it the needle it self thats jumping like it gets stuck then jumps up or is the revs jumping up and down

[dezz]

If it's got white faced/aftermarket cluster faces on it, the added thickness of another layer can cause the RPM needle to stick/release randomly....

It doesn't even count revs or get stuck that I noticed. It just really fast all over the place.

Think of setting a clock and just spinning the needle backwards and forwards really fast. It's just all over the place, both when driving and idle.

Thanks for the replies

the cluster itself is f**ked. skylines are notorious for it. has nothing to do with ignition. rev tacho jumps everywhere wildly.

Happend to mine a while back, took it to the mechanic who fixed in a sec, didnt see what he did but i think it was loose or something

So just replace the cluster and it should be fine?

Which mechanic did you take it to?

could be loose wiring to the cluster, could be a dud connection inside the cluster for the tacho. play around with the wiring first. then try putting in a new one. as i said 2 mates skylines got the exact same thing happening, new cluster problem solved.

cheers.
