The lower left flipper on my newly acquired Party Animal is intermittently machine gunning. It's a double stack switch-- one set controls the lower flipper, the other sends a signal to the upper coil. I don't have a ton of experience with multi flippered machines, but this is a bit different than my other experiences.
I have played with the EOS switch until I'm blue in the face. Last night I reflowed both the coil connections and the switch connections... and that's when I noticed a couple of tabs of wire coming off the right side pair of that double switch stack, as though someone had cut a diode, resistor, or cap out of the connection. In looking at the schematic I saw the snippet below-- am I to read that as a cap bridging the two sides of that switch? Could the lack of this cap be what's causing my machine gunning problem? If I've read this wrong, the full schematic is at http://mirror2.ipdb.org/files/1763/Bally_1987_Party_Animal_Manual_Section_2_Schematics.pdf - and this particular snippet comes from page 48.
