Very good catch

MAC-35A - AAA - DBAA - 1BA is the much harder to find 12 volt DC solenoid
MAC-35A - AAA - DDAA - 1BA is the VERY COMMON 24 volt DC solenoid

what's inportant is to use a (BI-DIRECTIONAL SOLENOID)
Because
most solenoids and standard SKINNER valves - WILL HOLD PRESSURE ONLY IN ONE DIRECTION


and not to worry - I had the former Members permission to use and modify the (before & After)  picture

Hate to reply to my own post.I do recall someone on this sight replacing the leveling valve arm with a actuator,(3 position I assume).when the actuator was returned to the neutral position,the bus would revert back to auto. Does this seem workable?  thanks ,, mike

linear actuator. Basicly does same as my barn door system only it is electric. It lies to the leveling valve so it reacts to do it's normal function. I used what I was comfortable with. Sean is comfortable with electric control. Same result we both use stock leveling valve to do job. The coach I  am doing now has a 5 valve leveling system from factory. Part of it is missing.  I will prob go back to kiss system. Or even maybe try the linear actuator system. The factory system looks like it could have allot go wrong with it.   Bob

Ok, I see the photo using the 24v valves, but how does one go about releasing air from the air bags before you start to do the leveling. I have seen some S&S motor homes release all their air and settle down and then start to level refilling the bags as needed to level.

I've never seen a working leveling system in a bus but from some of the pictures I have seen, it looks like there are brass mufflers on the air valve switches at the guages. That leads me to believe the air releases at the air valve switch but I also would like to know for sure.
