RPM is read off the tach wire to the ignition box. Check the connection, shouldn't be a butt connector but soldered and terminal into ignition box. Do you have a tach connected also or reading rpm through intelligauge or RP dash? Could be a conflict with tach also, but much less likely. I would check wire for damage and faulty connection
