The tach gets + signal from the ignitor (pin #15). It should be a Red wire.



That is a scary thought. CDI starts to go bad then sends bad voltage to the tach as well as coils. Everything gets hot etc. etc. Or the cheap solution, bad grounds are the cause of all of it. A 4.00 connection breaking a 400.00 CDI over time.

Don't weak connections and marginal grounds cause components to overheat?
