What is this?
#1

Does anyone know what this is?

It is mounted to the air tank over the tag axle. It has some wires going to it.

It is leaking air so I need to replace it. I don't know what to search for . . . .

Thanks in advance!

Kyle where do the airlines go? That will provide a clue. What happens if you disconnect
The wiring?

Air pressure sending unit I think. They can be used for several purposes. You can buy them at NAPA.

I am the head caretaker and floor sweeper on my dads coach. Also the one who drives it to Oklahoma for him for service.

I believe it's likely the air pressure switch that triggers the low air pressure warning. And yes they can leak. The one on my 93 coach did a year or so ago.

It is a LP-3 low pressure switch. NAPA was able to get one for me today. I put it on after work. Only took 3 hours. . . . If you could see it, you couldn't reach it - if you could reach it, you couldn't see it.

Why did they use screw on terminals ? The slip on spade would have saved over an hour . . . .

If this part isn't the part they built the coach around, it's got to be the second!

Ironic that the low pressure switch was causing the low pressure . . . .

I also replaced the air tank moisture pull drain valves on the front 2 tanks. Now, my brake air pressure is at 90 psi 4 days.

The main air stays above 90psi for well over an hour now.

AND, I was able to get the air operated step cover slide working - added a pressure regulator & cleaned some electrical connections.

Nice when more stuff works ! ! ! !

Obviously it was "on" and doing it's job....
