Replacement Control Board to Driver Board Cable for use in Gottlieb System 1 Pinball Machines.
Self Repair Notes:
If some or all of the pins on your cable need to be replaced (see information below) you can purchase the following parts at electronics suppliers like Mouser, Digi-Key or Allied Electronics. Cut off your existing pins (one at a time, so you don't mix them up) then strip the wire, and crimp on a new pin. We may provide a kit a some point, but for now, we are providing this information for those who have asked for help.
Pins (contacts, terminals)
or Molex 08-52-0072
Connector 24 Pin
Molex 09-01-6241 (available from Great Plain Electronics)
only needed if your connector is broken
Crimp Tool (Economy)
about $20 If using this tool you may consider also soldering the wire to the pin for a better connection.
Crimp Tool (Professional)
or Molex HTR2445A
about $15 This tool is a must for removing the pins, insert the tool under the pin to release the locking tab, then remove the pin by pulling on the wire, it should come out gently if the tool is properly inserted.
These new cables have all new parts. If you have replaced the control board and/or driver board, you also need one of these cables. This cable is the cause of many problems with these machines, from machine not working or starting, lamps or solenoids that don't work or work intermittently. If you replaced an old control board that had battery acid damage (green or white looking dust on the board or connector pins) then you definitely need one of these cables. This cable could solve those problems! This is the cable that goes from the A1-J5 connector on the bottom of the Control Board to the A3-J1 connector on the top of the Driver Board.
Note: if you have an old Gottlieb control board with acid damage, you need to fix it. This cable will fix damage already caused buy acid damage to the pins on the board.
Examples of battery acid damage:
(click on pictures for larger view)
Example of bad pins:
(Pins on left has greenish or whitish tint) (pins on top right has tab broken)
Example of bad pins in connector:
(3 pins on left are old, whitish tint, tabs have lost tension-sits lower in connector, causes bad connections) (3 pins on right are NEW, bright shinny, full tension, good connection)
Advantages of our NEW cable.
All new components, not 30 years old! New connectors, new pins, new wire.
(Wire colors my vary from pictures.)
NEW pins. The pins on old machines can loose their tension over time, they can also have poor connections due to battery acid damage from old control boards.
NEW connectors. Old and brittle connectors that are cracked can cause loose connections on the pins.
We use larger 20AWG wire on the control wires, this provide a stronger connection on the new pins to avoid the potential of being pulled out or broken off.
Our cable has nice curved design as opposed to the original straight across layout. Ours fits nice on the original Gottlieb control board or the replacement Ni-Wumpf or Pascal PI-1 boards.

Troubleshooting Existing Boards and Cables
Our new driver board can correct problems ranging from dim lamps, not working lamps, not working chimes, or drop targets that won't reset. You can test some of these features with the self test mode on the CPU control board. See your manual for instructions on how to test the outputs of the driver board. If you find that some of your lamps still don't work even after you have replaced the lamp, the problem could be in the driver board. If your drop targets don't always reset, the problem could be a transistor on the driver board.
System 1 machines have been known to have problems with CPU boards that have leaky batteries that have caused corrosion to the cable between the CPU board and the driver board. You should check the pins on the connectors to see if any pins are broken, corroded or weak spring force. If you have replaced your CPU board with a new version because of battery corrosion, you should definitely check the connector pins. Order a new cable with our driver board!
There is also some good information on connector problems located here:www.PinWiki.com
IMPORTANT WARNING...never remove the connector at the displays or control boards or driver board without first turning the machine OFF. You will probably damage the control board!
