Hi, my db1 92 integra rpm clock not working..
The car is running, the rpm is not running. (indicator clock is new)
what is the problem?

 

Do you mean the gauge cluster is new? if so was it from the same year integra?

If your RPM is not working its most likely the signal coming from the distributer, Its usually a blue wire coming off the back of the plug on the distributor harness that plugs in the distributor.

 

Thanks for the answer, Ignition module output signal is not present.
I changed the ignition module.
Problem solved
