Working on a 1993 Williams Indy Jones pinball today. The path of adventure (PoA) was not working, would not rotate right or left. After checking voltages, without finding any problems, decided to examine the PoA driver board (mounted under the the playfield.) Found the 100mfd capacitor at C3 was leaking, and destroyed a copper trace on the board. Replaced the capacitor and fixed the broken trace, and now the PoA was working great!
