Quoted from jlock:I would like to ask a follow-up question; I appreciate your help and patience. What is supposed to happen when the machine is in switch test mode and the disk gets spun? I would have expected that would trigger some switches. But nothing happens. I looked under the playfield and the connectors to the sensor immediately below the disk shaft are apparently all connected. Am I wrong that spinning the disk in switch test mode should do anything? Thanks.
I just checked on mine and spinning the disc while it's down in the regular switch test menu doesn't register, so that test must not be applicable to the disc. If you go into Diagnostics-Game instead of Diagnostics-Switch there are two menu items for the disc. One is the Strange Motor test that raises and lowers the disc and the other is the Strange Disc test that checks how well the disc is registering. That one is the test described in the instructions for raising and lowering the height of the disc and needs to be done with the disc down by using the Strange Motor test to lower it first.
