everything else on cluster works. RPM's dont budge so no signal is being received at all.

Ideas of what is most comon problems before I start taking shit apart?

im going to test the ECU and make sure the pin that sends signal is actually sending power other than that idk what could be the cause.

 

My zenki had a retarded rpm needle. It would rise super late, sometimes it wouldn't even move at all. Swaped out the internals and now it works perfectly.

 

Im just hoping its something simple cause so far the white faced clusters are hard to find and expensive... I dont want a JDM cluster cause same shit as USDM.

 

you shouldn't have to change the gauge itself, just the guts for the needle. (not sure how else to describe it)

More than likely, if you haven't had any major work done, or anything else crazy going on, the needle just crapped out.
