Trying to sort this out so I can call off the service guy. Got my head on straight about how the controls work and, while the weather stinks, it mostly is not raining. Here is how it went.
Combine started right up and the rotor/fan toggle turned it on just fine. At full RPM I turned the dials on the overhead console all the way to the left to get them out of the equation. Used the rocker switch on my right to increase rotor speed. It SLOWLY increased in speed 10 rpm at a time until it got up around 1000 and then I stopped as that seemed very high. Tried the rocker to slow it down and it gradually slowed it down to about 860 and then stopped responding.
I then tried to adjust the fan speed in the same manner but it was completely unresponsive to the rocker switch in either faster or slower.
This is how I understand these work from the manual and forum responses. Am I not understanding something or are these switches malfunctioning? I have not had time to address the ground yet but will look at it this weekend.
