valve problem need help

 i just got my new asco valves hook up.And I have a couple problems.. When I hit a switch up it also blowsout the dump. and one of the dump when i hit it, it will pull air from the tank, I aint got a clue how it would pass the fill valve to do that. I have the hot and ground at the two top post of the solinoid. do i need to hook some thing to the other post. or could my switches be messed up and making it act weird.

Is it a block valve or single valves? Possibly you have them wired together so that when you fill it opens the dump as well. Just an idea can you get a pic of your wiring?

single valves with avs switches. the wiring is wired from the valve straight to the junction box. box it labled what goes where I doubled check and all is where should be. could that box be messed up

It is possible the wiring could be jacked up in the box because the fill is obviously not stuck open and there is no way for air to spew out the dump when trying to fill. Does it have a pancake all up/down switch? I could be the wiring inside is fucked up and the wires are crossed causing it to fill/dump at same time. My other box was wired like that I had to rip everything apart and rewire it.

possibly you have your valves plumbed wrong. If not its most likely your AVS box. I had problems with mine and i have read several other storys on here about there boxes fucking up. Actually one of my friends did the same thing. But usual  Asco valves dont have any problems that ive heard of. They are the best valves for the money.

cool thanks for the help.

Do you have the flow direction correct?
