My stock tach is peged over past 8000 rpm. I have only had it running for a couple min but the tach didnt move. My question is is the cluster messed up or is it just not hooked up right?

 

Check the white wire coming off the gray connector on the ignition coil. That is your tachometer wire to the dash.

 

i am sure the wire is hooked up! but still no change! i unpluged the cluster and it came back to 0 put the cluster back in started the car and pegged the tach again. Any ideas?
I saw the test you posted for someone else might try that soon!?
unless you think cluster is bad
Thanks for you help!
