I'm trying to trace a power issue on a Quadra 800 (Wombat) motherboard where I think I have a 5v short to ground. Or at least I did.. continuity between pins 2/3/4 to ground on the power supply connector. That was until I realised my fully working Q800 does that too.. and so does my Iici. So why does it do that, and why doesn't the 12v or other pins follow suit?
