I'm in the process of installing a kitchenette into my 7 passenger Syncro and
I'm confused as to how the Refrigerator Heater Relay is setup.  I have
installed a battery isolator ,(as detailed on Harold and Nancy's webpage.
Thanks. :) ), for my auxiliary battery. I'm assuming that the battery
positive attaches to the 87 terminal of the relay. Terminal 30 attaches to
the refrigerator. Terminal 86 would attach to G4 on the fuse panel per
Bentley ( 12V when the ignition switch is on).  The Bentley schematic 97.33b
seems to show 86 and 85 as the coil to pull in the voltage for the
refrigerator. I'm not sure why terminal 85 is there. Can someone explain the
theory of operation? Do I need to wire this differently than the Bentley now
that I have an isolator?
