Thanks for the above and I will seek higher advise & meter what is advised.
I would wire the incoming hot wire to the terminal that goes to the resistor common. That will allow the resistor to act as a current limiter if the thing shorts someplace else. I would connect the resistor tap wire to the lower carbon arm. I would wire the incoming neutral to the solenoid coil, and the other side of the solenoid coil seems to go to the other carbon arm. (?)
Got it mostly in understanding and will get shop help that know more. What you specifiy agrees with fixture head markings.
And other side of solenoid coil goes to carbon arc.
W-Shaped solenoid, one arm shorts to frame in a way that somehow cancels the arch I think in adjustable shorting to frame.
Hot wire thru resistor coil than lower arm, neutral directly to solenoid than upper arm.
Still a question remaining of given the lower part of the coils are attached to hot... there is brackets or rings to adjustable tap the power from them above, but I still have like +6" of wiring at the top of the resistor coil that in my fault... I don't remember where or how such wiring above the brackets, they were terminated. Literally 6" now hot wires just hanging out. I doubt they connect to neutral, or get shoved to the underside between coil and ceramic. What do do with them given once a resistance of an arc is struck - those wires sticking out from the top of the coil springs - if touching something would easily be less resistance than the arc. I would hate to cut them given they are original length.
