Air Compressor External Hose Not Working

[Ripley345]

Hello
The hose connection in my 1988 345 is not working. Mind you the RV is on jacks so i don't know if it is engaging for the airbags. But i did jump the solenoid and that worked fine, but not very convenient.

Any thoughts as to how to get the compressor hose connection to engage?

Thanks

On our 310, the external air hose quick connect and the rear air bags are both supplied by the big air tank near the rear axle, which is supplied by the air compressor. So, is the problem that you have no air pressure in the tank, and when you turn the ignition to "on" the compressor does not run?

Yes I am thinking that maybe the compressor is not coming on. I checked the fuse up front and it had blown, but still not happening. I have a couple of other things like turn signals and radio all hooked to ignition and they are not working either. all this was working for a bout5 miles then stopped. I did jump the compressor at the solenoid and it operated. but when i plug the quick connect in i don't get any air unless i jump the solenoid.

Well, it does sound like an electrical problem up front somewhere, but I am the wrong guy to advise you on tracing it. All that I would do is turn the ignition on, use a tester to confirm that you are not getting 12v at the compressor, and work toward the power source from there.

Hi Thank you.

I think I am in need to a pretty technical skill. I have pulled out the dash and besides having some lose wires and good fuses, I am stumped. I will consider taking to the shop.
