Re: Shock when touching power supply case (ACBel API1PC36 from PowerMac G4 MDD)
Exactly, looking at all the data, I agree it's possible I simply touched something live inside the case (ideally don't touch one with the PS live and case open...). I see there's a copper colored heatsink relatively close to the edge of the case.
My concern is there's no way to be sure unless I touch it again with it in the same/similar setup to see if I get another shock - or better yet if there was some way to measure it.
Would it be possible for the PS to still work ok...

The resistance of the power strip's ground pin to the PS case is good, less an an Ohm (with the PS power cable plugged into the power strip).
I get the same, less than an Ohm measuring between the PS power connector ground pin and the PS case.
When I was shocked, I don't believe I was holding or touching anything else but I really can't say for sure.

I confirmed there is at least continuity between the ground pin on the PS power socket and the case (as well as a few other ground points, like the PS screws, etc)
For the AC outlet, I checked it was grounded by using a multimeter to confirm I was getting a voltage (120V AC) between the hot (short) socket slot and the ground slot.

Shock when touching power supply case (ACBel API1PC36 from PowerMac G4 MDD)
Hello!
I recently successfully repaired two Apple PowerMac G4 MDD power supplies by swapping out bad caps, per excellent info found in various threads on this forum - yay!
I was doing testing on one of them, the ACBel API1PC36, with it's case open and had it setup outside of the PowerMac resting on the table with it's power connected to the system (power was also connected to a couple SCSI HDD drives, for a bit extra load). It was working fine, I shut down the system but did not unplug the PS from the power strip (and power strip was left on) so power was going into...

PowerMac G4 MDD ACBel Power Supply issues (API1PC36 400W)
Hello!
First want to thank folks on this forum (Toasty, etc) for the very useful info I've found here that has allowed me to repair a PowerMac G4 MDD Samsung power supply and get this ACBel one working better!
I got a PowerMac G4 MDD for free as it was dead (not booting at all). I was able to confirm it was it's ACBel power supply as another (above mentioned Samsung) power supply works ok with the system.
With this ACBel power supply installed, the system would not boot at all, no power light blink, nothing. I've gone ahead and replaced the "12...
