Swap out all of those #313s with #44s or #47s and never worry about looking for the correct bulb again.Ĥ Replacing the Black Hole "Spinning Disk" Motor The bulbs now will light on 6VDC instead of 24VDC. To enable to bypass, simply unplug the molex you installed above, and plug each end into the molex on the wires you just ran that lead to the Q-Relay.Īll finished with the mod.Put a male molex on one wire, and a female on the other.Now run a pair of wires from the switch stack through the harness across the bottom over to where you cut the BLUE-BLUE-BROWN wire.This is how you will revert it back to factory condition. Cut the wire and put a male molex connector on one end, and a female on the other.Pull the wire out a little to give yourself some room to work.It may be easiest to trace it down the playfield from the ball gate solenoid. Now locate the BLUE-BLUE-BROWN wire under the playfield near the right side playfield hinge.Adjust the switch now while you have it out. Now the Q-Relay will activate the existing switch stack and the new one you just added. Add your new single circuit NO switch stack to the other side.Unscrew the relay from the playfield, and simply move the existing switch stack from the center position to one of the outside positions.It is on the underside of the playfield, near the left side hinge. 062 single-circuit molex connectors with pins and sockets available at pinball parts stores and arcade parts stores), and about 4 ft of 20AWG wire (any color). The only supplies you will need are a Gottlieb single circuit NO leaf switch stack (available at all the major pinball parts stores), 2 pairs of. In a nutshell, we're going to add a circuit to the Q-Relay (game over relay) so that the gate is only capable of being energized when a game is being played. So when the lamps flash their sequence, the gate moves when they machine triggers what it thinks is a lamp at that location.įortunately, its an easy fix, and can be reverted back to factory condition if needed. They forgot that the right hand side ball gate is controlled by a lamp driver, not a solenoid driver. Gottlieb made an oversight when they programmed the attract mode for the lamp sequence. The order shown in the manual vs the actual test order follows.Ģ Stopping that Gate Chatter in Attract Mode One such error in the Gottlieb® Black Hole manual lists the solenoid numbers and solenoids pulsed during solenoid test incorrectly. 9 Black Hole Lower Playfield Ball Gate Wireformġ Black Hole Solenoid Manual Solenoid Listing IncorrectĮrrors in game manuals are fairly prevalent. 7 Pull Up Resistors Added to Remote Transistors (Centrally Located) on Lower Playfield.4 Replacing the Black Hole "Spinning Disk" Motor.3 Replacing Black Hole Lower Playfield Illumination Lamps with #44 Lamps.2 Stopping that Gate Chatter in Attract Mode.1 Black Hole Solenoid Manual Solenoid Listing Incorrect.‘I will convince you that I do know by clapping you for the remainder of the night into the black hole, young gentleman, do you see, and have no doubt but the air of that agreeable apartment will restore your senses. 1808–10, William Hickey, Memoirs of a Georgian Rake, Folio Society 1995, p.A place of punitive confinement a lockup or cell a military guardroom.Widespread popularisation of the term is generally credited to a 1967 lecture by physicist John Wheeler. The first known usage in print was by journalist Ann Ewing in 1964. Dicke, who stated around 1960–1961 that the objects were "like the Black Hole of Calcutta". In reference to celestial bodies, physicist Hong-Yee Chiu attributed the term to his colleague Robert H. Black hole Wikipedia The first image of a black hole, released in 2019.
