JDM SiR Cluster, Tachometer stoped working. How do you fix?
 

Hi.
I've been running a JDM SiR cluster in my 93 B16A2 powered car for the past 4 years, and the Tachometer recently stopped working.
It doesnt get off the needle-rest, and only vibrates down there. sometimes it jumps up but goes back t the rest position.

Is there something I can do to fix this?

Thanks.
