Now what, Auxiliary compressor blows pressure relief valve every minute?
The coach is hooked up to the 50 A supply, but I do not keep the compressor switched on when stored.
But I decided on the weekend to start the engine, generator, A/C units, aquahot and air compressor for a system check-up.
A/C units cool, but are very noisy, but this is a different story. Will replace them this winter.
When I started the air compressor to move the two slides out and then in again the yellow light never switched from intermittent to solid yellow. The air compressor ran continuously, the pressure gauge did not show anything and the pressure relief valve (on top of moisture relief valve on picture 450 on the right wall) popped every minute or so.
The compressor obviously worked, otherwise there would be no popping sound. So somewhere there must be a blockage.
The white line from the compressor discharge side goes to the moisture relief valve, and from there into to the back of the desiccant container on the left side of the picture inside the aluminum angle iron. From there the air comes out on the front of the desiccant container in the black hose going into another moisture separator (reddish looking).
This looked like a strange setup to me, and a call to one of my two forum advisors (can not give out their names, but one is of Swedish descent and knows everything about control systems and the other one speaks German and knows everything about internal combustion engines that there is to know) confirmed that the desiccant container is the most likely culprit.
Removed it, (see picture 928), it was totally blocked. I then rerouted the air line and that solved the problem.
I found the model of the 1 gal desiccant container on the internet, prices vary from $ 100 to m$ 200, and can certainly buy and install one if it makes sense.
Has anyone else this unit installed, is it an after market installation of a previous owner?
Regards
Klaus
