After a pretty decent length of time, and alot of fun games, the lever for the "B" switch at the top of the playfield on my Sorcerer is starting to fail. When the ball rolls over it, it's not pushing it down enough to engage the actual switch. I worked on it about a week ago, and got it working again, but now she's starting to do the same thing all over again. The switch underneath works fine, it's just the actuator lever getting out of alignment somehow.

I'm curious to know what would make this one lever start to fail when the others are fine? Is it just an age thing? Is there a standard adjustment procedure or measurement for these lever/switch combos so you're not just rigging them up to work again?
 
Sounds like it just needs to be bent a bit so that it hits the switch easier. It may have been tweaked a bit over the years. When I put my High Speed back together, there were tons of little adjustments that needed to be made. I know I had to bend a few of those a little. At least one because I bent it while working on something else.

It was probably just barely making contact when you got it, which seems to be the most common cause of things continually breaking down. Bend it so it easily makes contact with the switch, that way, if it loosens up a little, it will still work.
 
Take a buisness card, fold it in half, and place it between the points of the switch. Hold the switch points together and rub the card back and forth. This will clean the points on the switch. Next make sure the swich contacts close when the wireform is pushed down, adjust the points so that they wipe each other when they are in contact, this will help to clean the contacts when they are in use. When you are in diagnostics with the playfield down, roll a ball over the switch, if it only registers part of the time, re-adjust the switch. If you cannot get the switch to register every time reliably, then you will need to replace the switch.

Yeah, it's probably getting close to replacement time. The machine was made in 1985.
