Default help!!! rpm signal disappear after 6500rpm

anyone care to shed some light on this subject long story short

top my car out in 5th gear at 9500rpm doing 150mph+
my distributor took a crap due to the rotor bolt getting loose and moving around in there bent all the terminals inside complete deformed rotor...bolt got sandwich between two terminals on the ignitor...blew out a fuse and crack the ignitor.... spun all my bearings in the process

replace all the bearings car runs like a champ beside the rpm signal once i hit 6500 it shoots all the way to zero and all over the place...but car still pulling smoothly...i just like to know what rpm i am at therefore...

so i went head and replace the dizzy shaft new msd cap and rotor...
i am running an external SS blaster

any idea whats wrong with it?

It is none of those wires...... they have nothing to do with the RPM signal.... look on your distributor and look for the RPM signal wire. I want to say its a pink wire but im not 100% sure right off the top of my head... but follow that wire and make sure there is nothing wrong with it.... it could also be the distributor itself, try your friends and see what happens it only takes a few mins to trade them out

at one time my tach was doing the same thing. you may want to have the igniter looked at to see if it is bad. once i had put a new igniter in it was fine after that.


good luck

have you replaced the whole distributor? or tried another one that is working on another car?

where all the parts new or used that you replaced everything with?

Its the ignitor- thats the ONLY thing that sends the RPM signal to the tach.

Are you using OEM ignitors? MSD? Advance Auto? If they are OEM are they new? or used?
