Yep, that's where i'm heading anyway if i proceed to mount 2 fuses to isolate the headbox and playfield circuits.

Sadly the GI fuseholder wiring is hard-wired as 4 pairs of wires, 2 pairs to the headbox and 2 pairs to the playfield, they seem to be near the middle/ends of the wiring loops to compensate for current losses?

Maybe Plan-A will be to add 'connectors'  and go from there.

Thanx,
Marty.
