Quoted from gdonovan:No need to hack the wiring, you simply move the wire from the bridge to the fuse and add a short jumper wire from the fuse to bridge.
IMHO this is a mandatory upgrade as detailed by Williams and should never be undone, machines were catching fire. All machines made after a certain point came with the "upgrade" from the factory.
I say "upgrade" as it should have been on the machine day one.
This is a modification that "Should" have been designed into the game originally. It is a safety design that is built into any circuit with short condition possibility that has high amperage. Worrying about if it is OEM is not a consideration here. Just needs to be done.
On top of that it is an easy modification that requires no design change per-se.
