Start off by inspecting how it is sitting in the playfield. I removed mine, grounded down the top of the threaded bolt straight. Reinstalled it flush, checked and replaced the fuse and it was good to go. I also had the broken magnet error code.

Regardless of if it's working of not the magnet core will be worn like it's been hit with a hammer and should be repaired or replaced. image.jpg

Getting a new magnet core would be more of a tweak to get the magnet and ball operating more smoothly. The wiring appears to be the issue. Can you show a picture of the wiring at the magnet to confirm it's wired correctly.

Haha. We are posting at the same time. They appear the same.

I would start my taking the magnet assembly out and inspect the wiring for any kinks along with the magnet core wear.

It's working like HS2 magnets pushing the ball. I've exceeded my pay scale as to how the wiring does this. Maybe someone else can assist on this. I would still take out the magnet assembly out and inspect the wiring.

You have wires that are not hooked up to anything. That also should be addressed. They must hook up to something. If you changed the words to turbo force instead of magna force you would be good.

Maybe this thread may be of some assistance. I vaguely remember in my repair that the ball was getting
hung up by the magnet and grinding straight the magnet core and increasing the playfield angle fixed it.

But this is how you want the magnet to react.
