So I guess I'll try switching out both QCs on the tractor side - one is female, one male.
The switch is wired through a light to the solenoid in series, so it acts a use indicator. I don't find it useful, but hey, not my design.
When I took apart the dashboard to fix the joystick I accidentally pulled the light apart. Though I taped it back together, (I had to wiggle it first to get the connection to work, so I'm sure its a poor one) I could well believe that there is still a problem there. What surprises me is that the problem is affecting the remotes - I sort of figured that it was binary, either it worked or not. Not so sure anymore
So could voltage drop cause a solenoid to only open partially? That would make sense in terms of whats happening. I hear the solenoid moving when I turn the electrics on, but motor is still off. The "click" seems weaker than before, but could be my imagination.
I have a really basic and spotty understanding of electronics - any downside to taking that light out of the circuit? Meaning does it need that resistance, or could I hurt something by pushing too much juice through the system otherwise?
