My Teacher's Pet pinball was stored in a dusty garage for several years. Prior to that, it belonged to a family with lots of kids, where the cabinet was lovingly painted chocolate brown so that it would match the rest of the furniture. If that weren't enough, I recently discovered that some handy individual applied a good coat of what could be black axle grease to some of the coil sleeves and moving stepper parts.
I started it up, and the play field and the head both lit up. Pressing the button on the front activated the score reel reset relay and a pinball would be served up. The playfield seemed to want to work, but the score reels seemed sticky, the credit and ball count units never moved. After disassembling and cleaning the four score reels, credit and ball count units at first I wasn't able to get anything to work. With some fiddling around on the credit unit, I'm now able to get the game to light up, but it doesn't reset, which means I'm worse off than when I started.
I have the original schematic, which is difficult for me to understand and I've also been consulting pinside.com, which is full of good information and advice. I feel like I've reached a point where I'm stuck now. So what next? I'd greatly appreciate some pointers, ideas, etc here. I'm fairly new to pinball machines and have learned a lot so far, but not enough to figure this out on my own. Thanks for reading, I look forward to hearing back from you guys.
