98 S14 RPM gauge not working properly, spiking & sometimes not responding - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

title says it all really

i cant figure out why my RPM gauge is not working properly.

I start the car and the RPM gauge just goes all the way to the other side and sits there, sometimes it sits at 6-8 RPMs while driving, sometimes it spikes/shakes randomly.

Its a stock KA24 no work done to it, everything original.

Anyone have any suggestions what I can do to fix it?

Speed sensor or new cluster just so happens ill sell you a 97/98 cluster that works perfect for 100 shipped

Mine has original 118k miles, dont want to change the cluster.

Anyone else have suggestions? If its the speed sensor wouldnt it affect my speedometer

Oh its obviously a lemon. sell it back to whoever sold it to you the head is obviously warped.

Go through the FSM and locate the RPM signal wire. I bet you have a broken wire/loose connection somewhere. You can also check the back of the cluster as well.

Thanks I will try all your advice

You people really need to learn to keep your mouth shut if you don't know what's going on. You're doing more harm to the community than good with your bullshit guesses that are obvious ploys to get someone to buy stuff you're selling.

OP this will fix your tach.

This is an extremely common problem on these.

JR_SS wins for actually being close. It is a loose connection, but it's in the cluster.
