I recently fixed an issue on my skip ramp, which might be useful to others. The skip ramp would get stuck in the up position. The plunger (item 3 in the diagram, below) that slides through the coil/sleeve to raise the skip ramp is actuslly two parts --the bottom is connected to a metal rod using a roll pin (the meral rod is the one drilled with two holes to connect it to the lift bracket). The roll pin somehow managed to work its way almost halfway out and so the plunger could no longer travel smoothly through the coil sleeve.
Pinball 2000 was such an amazing modular design: pull three spade terminal connections off the coil, pull the molex that is connected to the switch, unscrew four screws and then you have the whole skip ramp assembly on your desk to work on. So civilized.
My repair was to push the roll pin back into the center of the plunger. Hopefully that lasts another 18 years.ade4dd1e8bcc683d9d584689081dcbce8199eceb (resized).jpg
