Onan Emerald Plus 5000
Wondering what exactly the bottom switch ( circuit bus 2 H.A.C.R.) in this picture controls? I've had a 2000 Suncruiser for 3 years and this is the way it's been since I bought it. What's it do? ...

Figured i'd follow up on this thread since you all took time to reply with valuable information. I do indeed have a bad 2nd compressor on my basement unit. When I throw that 20amp switch on the gen set and fire up the A/C, about 45 seconds into A/C run time the 2nd compressor tries to start and when it does it makes a horrific squealing noise. I clicked the thermostat off at that point and called it a day. I'm assuming this is why my switch on the gen set has been in this position since I bought the coach. The 1st A/C compressor does still work and will cool the coach, it just takes longer than I always thought it should. Now I know why.
