How can the manual not be accurate?
The flippers work the same way all non-solid state flippers work.

Quoted from MrWizzo:Zacaj, found many inaccuracies in manuals over twenty years of collecting. For example, his manual designates flipper connections on a P board not what is the J driver board.
P and J are for Plug and Jack. They don't refer to boards.
Quoted from MrWizzo:For example, does this system have flipper RAM?
What is flipper RAM?
Ah. Yes, it does have "flipper roms", but the "flipper" in that is just to differentiate from things like puck bowlers. They have nothing to do with the actual flippers, so no need to worry about that.
You'll see references like "2J3" and "2P3". the 2 refers to the board, with board number 2 being the driver board, board 1 being the mpu, and 3 being the power supply. the 3 refers to the connector on the board. J means it's a jack (header pins) on the board, P means it's a plug (connector housing) that plugs into the board.
As far as the playfield solenoid wiring diagram goes, this is going to be the most important part:Capture (resized).PNG
Is it both flippers on that side, or just one? If it's just 1 that narrows it down. Otherwise it's standard troubleshooting stuff. Do they have voltage, if you ground them do they fire, checking continuity between connectors, etc
