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.

Quoted from Robotworkshop:

Totally agree but it really doesn’t take much extra effort at all to make it looks like it belongs. These new bridge modules look like a nice clean easy way to do so. I’d use these.

Yes, it is a clean design. The only issue with this is normally the terminals to the BR's are soldered. Removing soldered terminals like these is not an easy task. With that said it is not hard to cut the wires and put new terminals on.

Still a must do update either way.

Quoted from Jigs:

They weren't soldered from the factory. If they are soldered you just put your soldering iron on the lug and pull with your free hand.

...and stand back when the solder flies!

If they were not soldered then it is super easy.

Was in pdf form a few years ago, scan of the original technical service bulletin.

I have read it as well in a service bulletin.
