Dump valve leak.

[bigdog]

For a bit now,I thought that I had an intermittent air bag leak and have now figgered that it's the dump valve not closing all the way when I'm airing up the system. I'm trying to find the valve and the control rods to see if it's just an adjustment to the rods or it's gonna take a new valve, but I'm having a problem finding where they are under the coach. If I throw the little handle to the closed position a few times,it'll stop leaking.

I have two dump solenoid, one front one rear. Black with a black line running to each. Find valves and check for leak when air will not build up.
