I'm doing this mod. Unfortunately, I can't reuse the original coils because the sleeves were melted in and the plunger wasn't sliding smoothly. The new Williams coil (FL23-600/30-2600) looks to be configured differently, so I want to make sure I attach the wires to the correct lugs, if anyone can confirm this:
Original coil:
Left: EOS switch
Center: Power return
Right: High voltage
Williams coil:
Left: High voltage
Center: EOS switch
Right: Power return

One terminal will have only a thick wire attached to it
One terminal will have only a thin wire attached to it
One terminal will have both a thick wire and a thin wire attached to it
The EOS switch will connect across the 2 terminals with thin wires, etc.
Thanks. It actually looks like I might have a problem with the Williams coil anyway. I don't know about how coil voltages work, but I see here https://www.flippers.com/coil-resistance.html that the FL-26-600/30-2600 uses 50v. I can't find any info on the Playmatic B-1008, but from the schematic it looks they're only being fed 30v.
Quoted from djreddog:If I recall correctly, the voltage is the reason we kept the existing coil.
30 seems like an odd voltage for flipper coils. I suppose that's to be expected with foreign made games. I ordered new ones.
Quoted from pefdude:So I ended up moving the front coil bracket back to the coil, drilled and tapped 6/32 holes to hold the Playmatic flipper coil into the System 11 flipper bracket (see other pics).
I don't have a 6/32 drill bit. Would a 3/16 work?
