Default Air system, what’s this ?

This part is leaking on my air system. What is it, does anyone have a part number ?

The round thing with two wires connected to it, and all the bubbles.

It’s right about over the front axle pretty close to center.

Doesn’t the low air buzzer have one wire to it ?

you could have the optional air leveling system.
Some were installed, but the electrical dash switch was not installed,
unless the owner paid for the option. A dealer could complete the install.

I think I found it, it’s the brake light switch Williams part #WM 777A which seems to a old part that’s not being made. Anyone have a replacement number.

If it was a brake light switch it would only leak when the brakes were applied. Was your pic taken with the brakes applied?
Also some pressure switches have an internal ground (one wire) and others use an external ground (two wire), but the function is the same.

Good point.
It was leaking with out the brakes applied ? The parking brake is set, but that wouldn’t cause the brake lights to activate. The switch is a Bendix SL-5, stop light switch.

Could the switch be used for something else ?

I’ll put air in the system and see if I still get air out of that port.

It was definitely leaking at least it was making bubbles.
