Found this:


The fliptronics board is in the upper left corner of the backbox. It could be a fliptronics 1 or II.

What you need is the WPC Schematics manual here:

http://www.pinrepair.com/wpc/wpc-89.pdf

There is one TIP36C and two TIP102s for each flipper. The TIP36C is the big transistor at the top of the board and the TIP102s are the smaller ones.

The Addams manual does not have schematics for the fliptronics boards in it but you need to read the manual because it will tell you which pins from the flippers lead to the connector on the fliptronics board.

So in the Addams manual the upper right flipper is connected to pins 4 and 6 on J902 (Or J802) (Page 3-10).

Jump to the WPC Schematics manual for the Fliptronics board (Page 13) and pins 4 and 6 lead to Q2 (TIP36C) and Q7/Q8 (TIP102s)

Test these transistors as described in Clay's guides (http://www.marvin3m.com/fix.htm). You will probably find that one of the lugs is shorted to ground (the top part of the transistor). Replace all three transistors regardless of which one tests bad.

BTW Fliptronics I boards will only work in Addams. You could technically buy a Fliptronics II board and it would work fine.
