Hello all - just acquired a Demo Man and have fixed all the issues with the exception of one: The Cyroclaw is throwing a "Magnet Broken" error. I checked continuity as the magnet is driven off the Fliptronics II board and I am getting some strange readings at the magnet coil lugs. When in test, both lugs read 0.43 vdc, then move to zero when the magnet test in engaged. I am probably doing something wrong, but everything else on the claw works fine. Does not seem to be much on this in the usual places, so anything is helpful. I did swap a new Fliptronics board in with the same result. Can the magnet actually be bad? That would be a first for me.

I disconnected the leads to the magnet lugs and it reads 99 ohms.
So if I am reading this correctly, that would mean the magnet is ok. Hard to believe a magnet would go bad, but I suppose it happens.
I swapped out the Fliptronics II board with a brand new one, and no change..
Appreciate both you gents very much for weighing in on this....

The sound you hear is me going "wow, and I guessed 100 ohms"!
That coil is good.
I am guessing that if you find the reason that there is not 50 V DC on
that coil, you will solve the problem. I suspect that fuse is blown.
If Q2 and Q8 are good, I don't know why the fuse would blow. Even if
the coil locked on, 50 V / 100 ohms is only 0.5A. The fuse is 3A SB.

Yes sir - awesome guess!
As mentioned, fuses are good so somewhere there is a break. I will report back.
Thank you Lex and John for responding, you set me on the right path!Epilogue: ALSO! While you have the Elevator Assy off the game, reflow all the connections on the PCB on the bottom of the assy, and also nix that Z connector!
Here is the resolution:
It ultimately wound up being a bad opto pair at SW. 74 Elevator Hold. What threw me was it was intermittent and appeared to be working fine, but by process of elimination I got there and found the emitter was flakey. I replaced the pair and voila: No magnet error, and claw/elevator/magnet function is 100%!
Bottom line: The magnet broken error had absolutely nothing to do with the magnet being broken - it was fine.
If you have a bad opto @ SW. 74, the game will throw a magnet broken error.
