Yes, remove the damn switch all together and hook up a relay from the magnet to the switch.
I've got one, and no matter how much adjusting I've done to it, the switch kept pushing out the ball. I fixed ol' butter fingers for good. I've played about... oh 100 games, and the hand has yet to drop the ball since. Before doing this mod, it would drop the ball almost every game. I thought I fixed it, a few games later... drop. Then I'd tweak it... drop. I put in all new wires in it and went as far as buying a new magnet. I finally fixed it before even installing my new magnet (still sitting around in my house).
So, WHERE do you find this miracle relay? Go to this url, it has a mini schematic on how to build it:

It cost me about 7 dollars to build, and works like a dream. What exactly does it do? You circumvent the stupid switch (which is why the ball always falls outta the hand)... when the magnet activates, you take the power going to it to a relay. The relay activates, which turns on the switch. You take that switch activation, and send it back to the machine (via the switch you just took out). It only activates for a second, but that's enough to satisfy the machine by lying to it... therefore, your JM pin thinks the switch is there.
Now, do you have to do all of this? No. You can rip the switch out all together, and not hook up the relay and it will play just fine. However, you will get the BONG BONG BONG warning when you turn on your machine. It's telling you "hey, the switch is broken." The game would still play fine without it.
So, wait a damn minute! If it plays fine without it, why's the switch even there?
Back in older software, the switch acted like an EOS switch on your flippers. When the switch triggered, the game would then reduce the power to the magnet to cause it to not overheat/break. But, with later software (and much like newer pins and EOS switches) the magnet goes to a power cycle after a few seconds anyhow. So no damage would happen.
But, I hate having credit dots. So, I installed the mod. Have been happy as hell since (installed it about 2-3 months ago).
UNRELATED TO THAT, does your spinner work? Many spinners on this need to be fixed to spin and stay standing straight up and down. That's an easy fix, if you need the answer to that one, too.
