Quoted from bigd1979:Ok so just got done my ww and its my first non wpc pin. I led the whole thing including the flashers and everything works with a little ghosting but not that bad however when I activate the flippers during a game the flashers flash and if I hold them in most of the flashers stay illuminated? Im assuming this isn't supposed to be doing this and im betting it goes away with regular incandescent flashers? So am I missing something or can I do something to stop it? Or is this normal for system 11 pins with led flashers?thax for any advice or help
Here is what I've gleaned from some other threads and confirmed with some very circuit wise guys that this will work. I personally never tried it and I'm selling the machine soon, but I'm confident it will work.
Cut off diode, d3,d4,d6, and d7 (just under the big tip36 transistors). Then add diodes to the solenoids 3a, 4a, 6a and 7a, White band on diode to power side on coils, usually yellow with purple stripe.
