Hi I'm Wayne

I will help you with this

check your wiring harness from governor to switches, make sure no rub marks in it

does the high speed arm always touch the governor stop ??

Customer: replied 1 year ago.
it does
Expert:  Wayne replied 1 year ago.

Thank you for that

check your harness very well for rub marks,

what is happening is that it is feeding 24 volts to the switch all the time

if all good, then it is the ECM faulty, keeping it in high speed

I hope this helped you
