Well John, he better spring for 2 tickets, 'cause I'd want in on the setup too!, (I'd keep my drawers on though)
So, here's my guess as to functions of various components:
Big switch labeled "1": main connection of generator to board, can switch polarity of generator connection to board with with switch. Switch 6 may perform this function, but I'm guessing 1
Knife switch to right of amp meter: sets the shunt for meter for the two different ranges (0-30,600) shown on the gauge.
Can't read smaller central gauge, but below is the cutout and below that the regulating relay for the
unit's built in voltage regulator. The regulating coil has a knob on the right for adjusting regulating voltage.
just to the right of the regulating coil and directly above switch "4" is what looks like an adjustable spark gap for magneto testing.
That's all I can make out on the board.
sure would like to know what the scale on the meter on the motor reads, has my curiosity aroused.
I can't decide if the rag on the motor's left end is to keep it from throwing oil or grease around or to tie the brush rotating mechanism in position.
Lastly, I'm thinking the black box in your first picture is some kind of decade resistance box. For making load tests on generators?
As for powering the unit, besides the 120vac to run the motor, they may just have used a battery for the fields, but it wouldn't have been necessary for most work, as the generator, if working should energize itself.
If it's not a problem, take some more closeup pics of the labels, us electrogeeks here on the board might figure out more.
Interrresting,,, verry interesting.
