auxilliary air compressor maintenance
Hi again Ron,

I've not seen one mounted in that fashion, and I'd prefer to be able to "see" the output; however, the point is you found it. Add a reminder to drain, to your monthly maintenance checklist, especially if you live in an area of humidity. The 12Volt compressor does not have a tank to drain, and the engine air compressor has a built-in air dryer which dryer cartridge should be changed every few years. > It > won't pull out of the floor so I assume it drains > beneath the coach.

For the 12V to come on when the 110V tank is drained must mean they are plumbed together. However, for the 12v to come on before the 110V must also mean their pressure regulators must be set in the reverse of what I would desire. > Last nite > the 110 volt compressor came on and made that air > sputtering sound that compressors make over a > hundred > times before 'closing', and then ran another minute > or > so before shutting down.

For what it's worth, my 110V will operate about 1 minute, "sputter" a couple of times, then shut down and will cycle in that manner about every 3-4 hours. The 12V compressors are notorious for wearing out their teflon-like, piston seal, and perhaps that is what is causing the prolonged operation you describe. Unfortunately, you cannot repair the 5 cent seal and must purchase a new $150 complete pump, if it fails. I became "pi##ed" (upset) at the seal problem and found a manufacturer who would produce the seals to order - however the minimum order was about 1 million seals for about $1,000 - not much help. A solution is to perform the replumb I mentioned previously, and to add a 12V switch to the 12V compressor pump to conserve/preserve their life. I note that some BB's have the switch factory installed and some do not.
