Pinball Specific Test Equipment Pinball Specific Test Equipment Hot

Here's a few pinball specific pieces of test equipment that come in handy whether you work on a lot of games or prefer something safer than jumpering your boards.  These products work well when testing a circuit board in-game, but really shine when testing a board on the bench.

Clockwise in the image from the upper left: Solenoid Circuit Tester, Special Solenoid Input Tester, Switch Matrix Tester, Opto Tester and Lamp Matrix Tester.  All except the Opto Tester, which is available from Pinbits, are available from Siegecraft.  Prices range from $8-$20.  

In the second image is a Williams WPC Dedicated Switch Tester ($12.50 for the kit and $25 assembled), the third image is a 64 Switch Matrix Tester ($47.50 for the kit and $90 assembled, plus the cost of the wiring harness) and the fourth image is a WPC Reverse Switch Tester ($10 for the kit and $15 assembled).  These products are available from Pinitech along with other pinball test equipment not covered here.

The Solenoid Circuit Tester press fits onto any 9 pin molex driver board connector.  Connect the alligator clip to 5 volts and when any solenoid is activated a LED on the bar graph will light up.  You can use this while sequencing the solenoids in diagnostics or in conjunction with the Special Solenoid Input Tester or the Switch Matrix Tester.

The Solenoid Input Tester press fits onto the special solenoid switch input connector on the driver board.  Connect the alligator clip to ground and each of the DIP switches acts as if a special solenoid switch was closed.

The Switch Matrix Tester plugs into the driver/cpu board.  Once installed just press a row and column button to simulate any switch in the matrix.

The Lamp Matrix Tester plugs into the driver/cpu board.  The 8x8 lamp matrix simulates the playfield lamp matrix.

The Opto Tester works off a 9V battery and tests the opto transmitter.  The sensor is very small and will fit in most places where you find optos.  Just point it at the transmitter and the sensor will emit a glow to indicate the opto transmitter is working.

The WPC Dedicated Switch Tester plugs into the cpu board (with or without a cable).  It can not only be used for troubleshooting but works great on the bench for controlling the cpu under test.

The 64 Switch Matrix Tester plugs into the driver/cpu board and works on most games manufactured since 1977 by using different adapter cables.  One nice feature is the DIP switches that allow you to close a switch and free up your hands for troubleshooting.  See the references for a product review.

The WPC Reverse Switch Tester identifies diode/switch problems that can cause phantom switch closures (when one switch is closed, one or more other switches also indicate closed).  This is really a must have since it turns a major, time-consuming project into a simple 30 minute test procedure.  See the references for a product review.
