Bob, best LOW COST fix is as follows. J.R. Slaten dash valves that replace
the round knob O.E. ones. Then, replace what ever compressor is there with
a 380C ViAir compressor. If the air tank is still good, use it. Make sure
that there is a check valve in line between the compressor and the tank.
The pressure switch should cycle the compressor in the 80 psi /120 psi
range. It is better to only use the ignition key to trigger a relay that
powers the compressor. No heavy currents should flow through through the
column. Check every single air line connection with children's bubble soap,
and show her how to do that. It will become a life's work chasing leaks in
all those hoses and valves. She should know how it is done. Check the
leveling valves and their linkages in the wheel wells of the coach as well
as the bags themselves for leaks. Once you have found and repaired all of
the leaks, you should have a fairly reliable system. If you want to go one
step further, consider installing shut off valves at the bags combined with
Schrader inflation fittings. Then, with only a cigarette lighter powered
air compressor, she will be able to inflate the bags and isolate them with
the shut off valves until the leaks can be found and repaired. 40 year old
plastic lines are like hard drives. They either have already failed, or,
they are about ready to. Thanks for helping keep her on the road. Good on
'ya , mate.
