Couple sys1's i have questions on:
Dragon - rebuilt the PSU, put it back into the game, ONLY plugged in power to the psu board. Was poking my DMM at the voltages to try and get the pot's aligned correctly and noticed the wire loom from the cabinet to bring power up was hot. Haven't noticed hot wires on any other sys1 games. Game GI all works with powered on.
Rollerdisco - lisy1 board, rottendog driver, rebuilt psu. I repinned a ground on A3J4 with the wrong pin. Friend played the game though, and it worked, then after a while he said the outhole kicker would kick then stay ON, and then all other coils stopped working. I went back today, repinned the correct pin. Game boots kicks a ball out, the outhole ball coil stays on and no other coil works, includes flippers, drop target reset. Tried swapping driver board from Dragon to roller disco, same behavior. Did a diod get blown on a coil, or is the lisy1 blown? this seems kinda nuts.
