I gave the z50 a half assed scrubbing :lol:
I'll soak it in simple green or something and pressure wash it maybe tomorrow. Also read about a method I might be able to use to start the F4 if it is the switch diode.
Basically I take the pot/volume switch out of an electric guitar (I've got a couple of junk ones), put it inline to the ecu, and dial down the voltage to see if that makes it start. :lol:
