Fezmid Did replacing the board fix your issue?? I've just conducted the same tests as you did, and same results, continuity in the wire is fine and the magnet reads at 4.5 ohms. Too give a little background, this happened to me before, I contacted Stern and they sent out a replacement board. Seemed to work maybe for a month, and now back to the same issue. Fuse blows once I turn on the pin.

Any other suggestions folks?

To follow on my issue, I've hunted high and low for a fix...couldn't find one so apologies in advance if I missed a fix.

Chas graciously shipped me another board which I've just installed, and the problem persists.

Problem: Dreaded F7 fuse blows once I turn on the pin.

Trouble-Shooting Completed: checked the ohms at the coffin magnet (reads 4.5) and checked the continuity in the wire going from the coffin magnet to the magnet PCB. Checks out fine.

Any ideas?

Well...must be Gremlins. Just got home from work, decided to take a look at the fuses. Put in another new fuse, working like a charm. Only thing I can figure is the new fuse I put in yesterday may have been burnt already. Guess maybe a good idea to test them before putting in. Weird!!
