The "Power Wiring" page in the schematic has an error.  It shows the DC ground wires coming out of the lamp and solenoid rectifiers as wired to 3P2 pins 1 & 4 on the P/S Board.  This is wrong.  It should be wired to pins 3 & 6.  In fact, later System 3 games show the correct wiring on their schematics (Lucky Seven and Disco Fever have been verified).

Modern replacement P/S boards use a fully shrouded connector for 3J2, so it is not possible to rotate the plug.  Not sure if 3P2 was wired this way from the factory or if someone re-pinned it later, followed the incorrect schematics, and later discovered that didn't work, so they rotated the plug.

2.2 Schematic Error on Power Supply Board Wiring for 3P2 Connector

The "Power Wiring" schematics page has an error. It shows the DC ground wires coming out of the lamp and solenoid rectifiers as being wired to 3P2 pins 1 & 4 on the power supply board. This is wrong. It should be wired to pins 3 & 6. In fact, later System 3 games show the correct wiring on their schematics (Lucky Seven and Disco Fever have been verified).

One example of a Hot Tip that had the wiring incorrectly (matching the incorrect schematic) on 3P2 had the plug rotated 180 degrees in order to make it work and to correct for the wiring/schematic error. It is only possible to do this on OEM power supply boards because they use a pancake connector for 3J2. It was unclear if 3P2 was wired this way from the factory or if someone re-pinned it later, followed the incorrect schematics, later discovered that it didn't work, and rotated the plug. Modern replacement power supply boards use a fully shrouded connector for 3J2, so it is not possible to rotate the plug.
