Is there a schematic for the circuit breakers and relays behind the passenger side panel? I have done a search and looked in my green book and can't find anything on these breakers and relays. I am searching for the relay for the auxiliary compressor on my '99. The later coaches have a different setup.
1. That should be print B-2197 or 2179 there should be one in the media section
2. It should be in the basement behind the fiberglass cover seems like it is the middle breaker in the breakers on the right hand side of the 2 rows. Look on the side for the reset button.

Can't seem to find it in the media section, I will call FT tomorrow and get one sent to me.
Chuck,
I've had time to think about our coach and the relay is on top of our compressor. It has a wire that is connected to it and there is a blade fuse holder that is hid in that wiring. The other thing that comes to mind is the pressure switch may be stuck not letting the compressor relay get the close signal.
Mike
Thanks Mike I will check that out tomorrow.
Here is B 2179. I hope this is what you are after Chuck
Not what I need Peter but I downloaded it as It isn't in my binder. I am looking for a schematic of the auxiliary air compressor. It never comes on as the air leveling system doesn't leak. Tested it just to see if it would work if I ever had a leak in the system and it didn't come on. Mike's info above had me go look at my compressor and there is a solenoid mounted above my compressor. Because of a full joey bed and the two storage drawers I will have to wait to see if there is an inline fuse in there next time I have the coach out of the storage canopy.
This is the kind of info I think I need. My compressor does not come on at all and I have yet to find a fuse. Bewildered
Hopefully this is what you need Chuck
@ Peter
That print is for the A/C system not the HWH system
@ Chuck
You should have the 600 system and this should help you out. The compressor print you are looking for is down near the bottom. I couldn't find this last night as IT department went to bed early. So my info was from memory and the Dr. has burnt up some of those brain cells.

Sorry I wasn't thinking.
The relay at my compressor had a bad lug, it was loose in the housing, not allowing power to go from the 12v+ side to the load/compressor side.
Here is what I replaced it with, everything works as it should now. I just have to chase some air leaks as the compressor cycles far more often than I am happy with (every 4-6 hours).
White Rodgers Solenoid For 12V Universal 120-105111-5 120-105112-2; WRS-120-9... (https://www.ebay.com/itm/255453075591?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649)
Edit: if you look at page 22 of the PDF that Pamela & Mike posted, what I have posted above from ebay is a replacement for what is called out as the 12V+ essex relay.
The compressor in my 2000 U320 only has a circuit breaker, which is located on the 12v wiring panel in the first bay, on the wall directly behind the battery bay on drivers side. The circuit breaker was bad for my compressor, and after I replaced it, I then found out the relay that sent power to the compressor was also bad. If you take a multi meter and test for 12V+ on both posts of the circuit breaker, you will know if the CB is good or bad. 12V+ on both posts means you CB is good. if 12v+ on only one post, it is likely the CB needs to be replaced.
