I have a 2 wire IACV. However thanks for the tip about interchangeability, I didn't realise that would be the case since mine is a rare 2.5-16 190. I actually had a spare but I lent it to someone else to help fix his 190 and can't get it back!
I am still inclined to think that these IACV's can't be very complicated and it can't be hard (if you can open it up) to diagnose what is wrong with it. If only to learn what happened and why it broke to prevent others from doing the same. Anyone ever tried to dismantle?? Or anyone know a good way to test them? What happens if I apply a straight 12v to it from a spare battery I have?
