[B and C]

Thank you Richard.  The 12v pump is turned off and when I turn off the 12v master switch the 120v compressor shuts down.  If I let it run, with the master switch on, the pressure builds to the cutoff point, ~102 psi, then shuts off n the pressure will drop over about an 1 1/2 hours to ~90 psi, then 120v kicks on and pressures the system up back up to the cutoff pressure.  Pressures are from the gauge off the pressure switch.
