Hi,

I was wondering if anyone is able to advise me on what is wrong with my standard tacho meter. The problem is that it isnt reading the right revs, there are times where it would just be flicking around, other times it would stay at 0 or even pass 9000 rpms. There are also days where it seems to be working fine, but it would only last awhile before it plays up again....

Would anyone have any ideas of why its playing up ?

Would be most apprecitated.

Had exactly the same issue mate,

Its definitely the tacho itself, not the signal to it. I put in a test cluster borrowed off a workshop and fixed the issue. I have since bought a new cluster and everything is peachy. There are automotive gauge repair companies who could no doubt repair your current cluster or you could try and find one second hand?

Now that you have made me think about this again... I still have my old dodgy cluster that i might pull apart at some stage and see if I can find the exact issue.

It doesnt affect my driving, its just that at times it flicks around like no tomorrow... had a mate tell me that it could be a loose connection...

with my situation (which sounds pretty much the same as yours) the tacho would work perfectly for maybe the first 10-15mins of driving. Then for me if it hit i think about 3500rpm it would almost hold for a second then shoot all of the fkn shop. then once i got past 4500 it would start working correctly again.

I really couldn't see this being a loose connection because for me it was a precise point every time. if for instance it happened at a different point on the tacho or sometimes you could go a whole days driving without the issue then maybe i would be considering that path.

im possibly thinking maybe a dry or dirty joint, perhaps only occurring when a certain frequency or voltage struggles to pass.

Does anyone know what kind of signal the tacho is taking (voltage and/or frequency change)?

      gauge needle removal

      By JC71 · Posted

      I have done a lot of research before posting here and on gtruk forum. couldn't find anything. I have my gauges all part except the needle itself. the needle has a extremely small hole in the center, but the shaft going to the needle is extremely small and appears to have nothing to index it either. doesn't seem strong enough to simple pry or pull without damaging something. Already tried the old spoon trick on a extra triple meter I have from a gtt, but no luck. the center cap comes off easily but the hole in the meter face plate aren't big enough to get over the needle itself. figured this would be my best place to find someone who might have actually removed theirs. wonder if there is some type of small pin press tool to push the pin in while pulling the needle base off.

      Ok...its taking me long enough to finally do this.  Feck financial security...heart disease will get me soon enough anyway So welcome to the garage..."Clem" Belsil80 has been running a 370Z in Super TT series. So after entering with him in last years Winton 300 i figured I  need my own car. Seems SAU Vic race cars need to be yellow....{tick} Reckon with enough motor i will be able to make up for the lack of talent and stay ahead of the 370Z... but the LS powered S13 and E36s are a ways up the road Aim is to have a car that doesnt stop or turn but has a bit of shed built motor with jam...maybe some cream  First step is getting this ex drift car log booked I am keeping faithful silver car. As the road-club car gets upgrades the race car wil get the sloppy seconds

      Assuming that they will come off without damage at all.... i would have thought just pull straight up off the spindle with a something or other than can reach underneath. Have you searched for youtube vids of people doing similar on R34s or any other Nissan from the same vintage? They should be the same technique, in all likelihhood.

      Wheel refurb?

      By GTSBoy · Posted

      Keeping in mind that sandblasting is really aggressive on softer metals like cast alloy, and you can do damage that you might regret. For trash wheels, not a problem. For wheels with value/scarcity issues, etc.... perhaps a less aggressive media is a better choice?
