Looking for some tech tips on a problem I am having.

Coffin magnet stopped working on my Metallica LE. I went into test mode and I had a tech alert that said "Check switch 64 Coffin magnet"

I ran some further diagnostic tests and in the switch alert section, it said that switch 64 coffin magnet was "Not in service", so adjusted it so that it said the switch was in service.

Now I have no tech alerts, but the coffin magnet still doesn't work in test or in play.
All the fuses are good and the associated lights are lit on the board.

I got a replacement magnet board from Stern and installed but still the magnet doesn't work.

Any suggestions on what I should do next?

Thanks,
Walt

I would check the drive transistor on the power driver board in the backbox with a meter first. It's also possible for the magnet to fail. The magnet is just a coil. Disconnect it and check it with a meter on ohms, less than 2.5 ohms and it's bad.
