Youngfarms has contacted me directly
He actually has his machine at Rocky Mountain ATV Service Dept (I did not know they did that, thought they were only parts...?)
He has as an older Rubicon 500 meter not showing speed and technician Eric at RMATV is sending it out to me
Sounds like speed circuit was fried on board due to previous sinking/bad voltage regulator and ECU possibly
