thanks for your responses so far!
1. The "Boost" switch is a momentary SPST over the driver's head
2. The House Batteries (two T-105s) are fully charged as is the Chassis Battery
3. The House Batteries are located aft of the left side rear axle, in a compartment that
also has the "Distribution Panel". In the pics below, you can see that the Distribution
Panel mimics the Gulfstream diagram, except that the "Aux Start Solenoid" is not
there, instead there is a square black relay
4. Staring at these pics for a while, I think I will look
behind this panel... it appears
the the black jacketed cable coming from the square hole and going to the lug on the
bottom of the fuse block just may be the "6ga Red" wire from the right terminal
of the solenoid ... I will start disassembling further tomorrow and will update
5. JaxDad, it certainly looks as you said, that the solonoid in the Distribution Panel
is
only energized by the momentary boost switch, so that must be the Aux Start
relay (solenoid)... and that there must be a charge relay (solenoid) under the hood.
