Tacho Is Jumpy

[Chessa]

Hi

Just wondering if anyone can suggest to me what this problem is...

My tacho is spastic. It reads fine most of the time but then sometime, especially when under acceleration or going over 110klm's it flicks around or reads very inaccurately. Just wondering if it is a bad connection or a bad electrical part of some sort, since it only happens under certain conditions.

So any suggestions on what it might be? How to fix and how much it might cost?

Hey

Sorry! Didn't even think of it! Its an R33 GTST... Series 2...

Hey Francesca,

Ron is right, it'll be your speedo cable. The R32s have it as a common fault based on their age, it is surprising to see a series 2 R33 with the problem.

The speedo flicks back from 110kmh to 100kmh? And sometimes bounces around when driving <40kmh?

Good news is that it is a cheap fix. New cable ($90 for R32) and DIY install.

erm.. he's said Tacho. Not speedo.

If it is his tach then I would be looking at the tach its self or CAS as the CAS is where the tach gets its signal from.

Joel FTW. Good point.

That said, I request a recount because the problem is occuring at a vehicular speed and not an engine rpm.

Yes it does sound strange.

Hey

Yeah its just the tacho that is spastic, nothing wrong with the speedo. Its just that the tacho mucks up either under acceleration (not all the time) and at speeds over 110km...

Maybe it does have something to do with revs but its funny that it would as it doesn't seem to discriminate at what revs it plays up at??

Thanks for your help!

Look at the cas and its drive. also the tacho its self.

Hey budy,

my '95 GTS-t S1 does exactly the same thing at about 3400rpm. For me it was physically the tacho, not any wiring. I have a brand new nismo cluster and no worries. But you dont need to spend much money to get yours working, there are plently of instrument repair companies around, or source yourself a second hand cluster.

sorry to hijack mildly - cowie was that speedo cable $90 from Nissan?

It was in that vicinity at trade/SAU NSW member price iirc.

Guys are paying around $80 for fitting but it is an easy job to DIY and take your wife/gf out for dinner instead

oh cheers, cowie, thanks mate.
