No leaks.

You say it levels with engine running. Do you mean via the ride height valves or the self leveling button? Two requirements for it to work is brake on and "for sure" in neutral.
Yes, Levels via ride height valves.
Brake witch tested ok at cpu.
Yes, in neutral.
Did the salesman switch get turned off accidentally
Mine came unplugged behind the dash
Found it, bad cable.
Thanks for replies.
Ok, so what's the salesman switch?
It is the 12VDC cut off switch located just as you come in the front door down low in the step well area. It doesn't cut off all coach side 12VDC but some selected items.
