Crazy Tacho After Comp And Leak Down Test?

[CRoNic...]

Hey everyone,

Just had the 32 GTR comp tested and leak down tested (all good) but ever since that, the tacho has been going crazy. It's fine for a few minutes, then out of the blue it jumps from 1k to 11k and then all over the place! Then it goes to 0 and then stays at 0 for about 20 seconds and then reads fine again.

It does it on a completely random basis. Most of the time it won't do it at all.

Would this be a faulty wire somewhere? Strange for it to happen right after the testing though, as I never had a problem before that! If it was a dash mechanical fault, would it do this all the time?

It's a Nismo 320k dash.

Cheers

has it done it again since you msgd me daniel? if it has start off by checking the plugs on the back of the dash,sometimes they can come loose and cause problems if that doesnt fix it it could also be a dry solder joint on the board.did you put the cluster in or was it already in when you bought the car?

Haha yeah dude, it was happening randomly after I messaged you. Yeah the dash came with the car - it was only ever taken apart a few months back to get the headlight switch fixed. It's not happening as much anymore, but I might rip out the dash this week, or I'll get Shaun to look at it next Tuesday when I take the car in!

I still gotta get that parker fixed, too. lol
