I don't have a fitting for my compressor that would work for that but I checked them with the battery and the 1 and 2 would click off and on. Nothing from the other one. Is that an exploded view of the valve body? I'm looking for those valves to be sticking or not right?

 

Hey I found a guy selling an A340H locally for $50. He was told it works and was removed for a V8 swap. I was thinking it might be a good idea for a parts donor? I could swap in the solenoids and maybe the valve body and see if that fixes things. For $50 I don't think that's could be a bad investment. What do you think?
