If you are looking at the line to the A solenoid at the box on a scope, it will be a square wave, based on zero, rising to 3 volts, the input to the dropping resistor is a 12 volt signal. The length of the wave varies with the duty cycle. A 5% wave is low pressure a 95% wave is full line pressure.

Happy hunting.

Right right, it does. For some reason I was thinking frequency, but that is what I meant. I suppose it would make sense for a duty % to be from 1 to 100. Ha. I'm starting to wonder if level 10 put the wrong kind of solenoid in the valve body. Surely it wouldn't plug in?
