ok i just bought me some parkers,theses are a little different then my other valves.these have 3 progs on them i know the big one in the middle id ground then there is 2 smaller ones i tried hookin one up onm each and nothin no click at all.helllp?!@
Try using just the 2 smaller ones, I know a few types of valves have that extra (usually bigger, or angled different) prong.. and the 2 that match are usually the ones you use. Post back if that works.
