Stupid Tacho

[jrocket]

Hey all. Yeah my tacho finally died to in my r33. It still shows a few revs but not working properly at all. I was just wondering, has anyone attually repaired one of these. I have taken the tacho out of the cluster and i now have it on the bench setup with some power so i can test it all out. I am just about to start checking out all the components etc and try and find what might be the problem.

Is it possible to fit maybe an aftermarket tacho in the same spot. I am not sure which way to go at the moment. I will just play around with in n see how i go.

Any info you have guys would be great.

Cheers

+1 for similar sort of problem ...

after I had overlays put on my dash the tacho needle started jumping wildly every now and then and also not working ...

would it be the sender perhaps ? or do you think it is something more sinister?

I have tested the signal coming from the ecu etc and you can see that it varies as you change the revs as expected. So i figure the signal must be all good. just the stupid tacho. I am having a play with it right at the moment. I will tell ya all how i go with it.

LOL sorry mate i will try to hurry up

I had a bit of a play with it. I am not sure what signal to give it to make it work. There is three wires that go to it. Ignition, Ground, and Signal. I connected up 12volts to the ignition and ground connections. I then put the meter across the signal and ground connections and it seemed to be giving out 9 volts. Not sure why this is. I was going to give it a variable voltage signal from 0.9 volts to 2 volts n see what that does.

I am not too sure tho if i am doing the right thing. I might have to do some more research i thinks.

Updates soon when i get more info.

mine flickers at 9000rpm at idle

mines stuffed aswell, just gonna find a second hand dash cluster to change the tacho over

[jrocket]

Yeah i might have to end up doing that too. My car is a 1995 series 1. I dunno if i can get a series 2 dash cluster and fit that. I not sure if they are the same or not.

It woudl be good tho to know what is wrong with the one i got tho. Might try an auto elec n see what they recon.

mines a 95 r33 aswell a mate of mine had an r33 gtr cluster in his gtst...only thing is it doesnt have the boost gauge (but who needs it if you have an aftermarket one)

[H@ME]

yeaha dun need the factor boost gauge, anyhow, i have a cluster here in my garage i think, a mate of mine in his fto has the same problem, thing is it hard to find second hand fto parts..

[jrocket]

Has any one fitted an aftermarket gauge in place where the factory tacho was?

S1 and S2 clusters are exactly the same.

As i think has already been posted the 33 gtr cluster or even the nismo cluster will plug straight into a gtst

Actually I don't think Series 1 and 2 are the same.

I'm having the same problem with a R33 series 2 Manual Turbo GTS-T with the flickering tacho.

The Series 2 one I have has 6 circles on the left hand side and 5 on the right hand side for warning lights and airbag indicator.

I have-

checked and cleaned the connections with no luck

reset the ecu with no luck

checked the for sales forum for R33 Series2 GTS-T manual turbo with no luck

checked 4 Import wreckers for the same cluster with no luck.

So has anyone managed to fix this problem without replacing the cluster?

or know if you can pull apart and replace the faulty Series 2 tacho with a Series 1 one?

Any help would be great or else I'm going to have to start looking interstate or overseas soon.

Cheers

Damn, mine just started freaking out today. Drive to bank, fine. Come out of bank, turn car on and tacho freaks out. Reads approx 1500 RPM higher than normal idle and movement, and is not steady but moves around erratically up or down 100-200 RPM. Would love to know a fix for this.

while i was changing my headunit i took my cluster out and cleaned connectors and made sure everything was on tight, still no luck

just get a second hand cluster (from ebay or here in the for sale section) and just change the tacho section, its only 4 or 5 tiny screws holding it in place
