this is my msq. I haven't done much of anything with it. I tried flicking the battery across the valve and it didn't move but it did make sparks, then reversed polarity and tried it again with same result. however the valve is working because megasquirt moves it, when I turn on megasquirt then the ...

I think I have it figured out. the valve opens at 0% pwm and closes at 100%. it only opens for about 1 second when I start megasquirt, so I'm assuming that it just stays closed until I start cranking (which I am not ready to do yet). is this right?

I have my pwm idle valve installed but I cannot get it to move. I have cycled from 0% to 100% with no change. I have installed the new transistor and the diode. 12v to one side of the valve fidle to the other. when I have the setting at 0% pwm then my meter reads 12v beetween the connections, and ...
