Leveling Incosistencies

[gmcbuffalo]

Anyone know the functions of each port on the 4 solenoid manifold?
I tried to listen and feel while the wife moved the switches, didn't help.

I know Jon does but he is currently soliciting pilots.

I think the 2nd one down is the drive mode.

If you unscrew and pull the plugs on them one at a time it will tell you.

Greg,

My coach uses 5 separate solenoids on the level low system (I hope that is what you are referring to). With your Prevost coach number and the prevostcar website, you can get a pneumatic drawing that is representative of you pneumatic system (This is how I sorted out my leaks). With the pneumatic drawing that pertains to your coach, the solenoids should be shown.

To see how a five solenoid level low system function, see below.

Greg,

If you are talking about the 5 port, another way to identify the "road position" valve is to leave the key on a few minutes and the valve will get very warm to the touch. If it is the 5 port, I think "road" is the middle one or
3rd down.

I have a 1991 XL and it only has 4 ports instead of 5. If you look at the Prevostcar webste and plug in your numbers it seem that you can not get any old info designs. For example try to get info on an 8V92 or a four speed transmission by telling them you have a 1991 MTH 40 XL. Doesn't happen for me.

That is why I ask if anyone knows the function of the ports.

I will start with the temp trick and then move to dissconnecting the wires after that.

Thanks.

I have examined my four port solinoid manifolds and the order of function is the same as solinoids 2-5 the five port. 1-Front, 2-Drive, 3, Right rear, 4-Left rear. The function of the add 1st solinoid was done by a 3 port Norgren just below the Solinoid manifold.

Good post Greg good info. IMO here is a good addition to the spares bin.
