It seem to me when you have the switch in the Down position you would get pulses from 1 OR 10 showing up on wire 7
When you have the switch in the UP position you should get pulses from 1 AND 10
Is there any continuity between the wires 1, 10 & 7 testing with a multimeter, don't be surprised if there's not, it may be capacitive coupled
I could go on guessing until the cows come home
I think you may have to contact the factory, perhaps your unit is faulty.
Did it ever work as advertised?
Is the motor running on both cylinders, both heads getting hot?
