I couldn't find a position on the ignition switch that energized the ACC BUS BAR. Is the key supposed to turn counter clockwise past the LOCK
position? I was trying to avoid the RUN position because my test jumper was nowhere near big enough to run the suspension compressor. I pulled the
suspension compressor CB and tried one time with the key switch set for RUN and still didn't get 12V at the ACC BUS.

Thoughts?

The background is that I was trying to figure out why the dash heater/ac blower wasn't getting power. I resorted to a jumper to get power to the
heater/ac fuse to chase that one down. The connector was off the switch at the control unit.

There is no belt on the dash AC compressor.

And the Onan had been removed.

One of the POs seemed adamant that there wasn't supposed to be any relief from the heat while underway...
