I recently got a Macintosh IIcx with some other stuff which is in need of repair. Today I went to power up the IIcx to see what the deal was...nothing.. not a single click, or so I thought. The noise the PSU was making was drowned out by the click of the power button. I held the power button, tick tock.. tick tock.. tick tock.. I noticed some movement in the PSU, so I took a look at it closer, thinking something was sparking inside. Tick tock.. tick tock.. tick tock, AH HA! I see a relay moving inside, and the PSU fan is running solid, no intermittent movement, hinting the caps may be good, maybe. What is this strange relay movement? Caps? Logic board caps? Shorted connection? What is going on here?!
