Solenoid Indicator / Tester / Fuse board - Williams System 3-11, Data East, Sega

This is an extremely versatile tool for testing and/or protecting pinball circuits where the solenoids connect to the MPU / Driver board with a 9-pin, .156" pitch molex connector.  Commonly found on Williams 3-11, Data East, Sega, and some others.

For use as a Fuse Board:  Populate the appropriate fuse holders.  Note:  If not using as a fuse board, Jumpers SJ1-SJ9 will need to be closed.

For Testing the MPU Solenoid Signals:  Connect to the header in question, and attach 5v to the Signal Indicators 5v connector point.  An active solenoid signal will light the corresponding red LED.

For testing coil power:  Connect to the header in question and attach ground to the Power Indicators Ground point.

This board comes standard with a 9-pin molex header.  If installing permanently on a particular position, clip the appropriate pin - Pin 2 for J11 and Pin 3 for J12 (pin 5 for J19, if you want to use it there).  If you are using this as a testing board, not dedicated to a certain position, a screw header can be installed, and 9-position pin strips can be provided.
