Help with Air Throttle

[Mike Hohnstein]

If you turn the wheels to the right full lock, you can see the treadle valve for the air throttle. Verify air is getting there, then crack the supply line to the throttle actuator and see if air is getting there. As it's been sorta cold, you might have some ice blocking supply. The bendix 'mess' is on the inside battery box wall. I think I'd start with a heat gun on all the lines with the air supply at pressure. Many potential blockage opportunities in that system.

Subject: [WanderlodgeForum] Help with Air Throttle

We fired up the Bird, after not running it for about two months,
and we have no foot throttle acceleration.

Our 88 FC has a Williams air control foot trottle.
And a Bendix Cruise Controll.

Both the foot throttle and the cruise control, share the same air
throttle cylinder.
This air cylinder with the attached cable to the injection pump,
works great, for the high / low idle, that is set by the Resume/Set
switches on the Bendix Cruise.
The foot brake also lowers the idle.

It appears that the Cruise control is out of the circuit
when turned "Off". The cruise worked great on our last trip.

So is there a check valve or air solenoid switch in the air plumbing
between the air supply and the foot throttle?? Where is it located??

Any help or ideas are needed and welcome.

I was able to get some information from the drawings, that Ralph has
in the files.
But these seem to be for a 6V or 8V and may be different than our FC.
