Pinballs

Since its purchase last November, the Student Prince didn't remain unattended: it first went through a series of checks, following as usual the neat tips of Pinrepair on this topic:

• Transformer ok
• Check of all coils (measuring their resistance)
• Visual check of all switches
• Cleanup of the stepper units

After an initial power up, new problems appeared:

• The Game Over Relay remained permanently energized. Problem solved by readjusting the control switch for this relay.
• The machine seems whimsical when it comes to performing general reset, and the hack suggested by Pinrepair to set the game to freeplay doesn't seem to work for us. For now we have to fiddle with the coins switches alternatively until we get a full reset.
• The score wheel for player 1's hundreds doesn't reset. Apparently a mechanical issue.
• The ball isn't served (probably related to the reset issues, as the switches are working properly there).

These details aside, the game is apparently working correctly at the playfield level. The flippers look pretty weak though (the ball can't get past half the playfield, even with a minimal inclination). We're waiting for the schematics to arrive before going any further.
