I'm attempting to test a Macintosh II that I'm about to begin working on. When I use my half double A battery to attempt a jumpstart by touching the end white wire pin and the case metal, all I get is a quick fan spin, a flicker, and the speaker making the usual popping sound when power is applied.
That tells me that the power supply is working, but something is preventing it to fully start up. The board is a Rev. A, which means it has no leaky caps, and it looks like it's in great shape.
Could it be that I'm not touching the jumpstart wires for long enough? Or could it be an unforeseen problem with the board? I was under the impression that it would still boot up but do the 4 note death chime if it had a hardware issue.
Thanks in advance for any assistance.
