Re: Acbel API1PC36 from an old Mac
I checked all of the voltage rails at the motherboard and no shorts. And then, well, it's a weird one. I changed 12 of the electrolytics before lunch, and did a quick check run. The symptoms were exactly the same - fan twitch, a red LED on the motherboard (D518) flashed once and nothing else happened. So I had lunch and before changing any more components I did another check run. The darn thing started and ran for 5 seconds. Two more restarts and it kept running. Why that should be the case I have no idea. There is a backup battery on the motherboard that currently tests as 3.65v, so I guess that can't have been a problem.
