No; there was no point in time when the stock PSU and the bad RAM were both installed at the same time. I figured I'd do both things at once... you'd think I'd know that I should only change one thing at a time by now.  I realize now I didn't make clear in my earlier post. In my defense, I...

Alright, so what I've ended up doing is rewiring a PC power supply to match the Quadra's power. At first, I wasn't getting it to work... but it turns out that was because the brand-new RAM I ordered was messing it up. When it was in Bank 1, the machine didn't chime, and when it was in Bank 4, it...

Make sure you're restarting after each time you change the switch settings. If you just so happen to have the same kind of adapter as I do, try turning on 2, 3, 6, and 7, and then applying power. That's what worked for me (check the reviews for other suggestions).

The fuse is intact.

Just tried this again, just to be sure; I checked to make sure nothing conductive was under the board, made sure all the pins were normal, I removed all the RAM and replaced it with one bank of brand-new modules in Bank A, I removed the NuBus card it came with, tried with and without the VRAM...

So, I recently got a Quadra 950 and had it shipped to me. Naturally, it was working, but shipping happened, and it's acting up a bit now. I've surmised that it has a problem similar to that described in this post. If I let it sit, then try turning it on with soft power immediately after...

Yep, that's one of the trollish things about these capacitors.  An electrolytic's stripes are negative, and a tantalum's stripes are positive.  Let this be a lesson to all who wander over here :p You could say that this was a ...shocking experience? ;) Or perhaps it was... enlightening...

Alright. Luckily I used duct tape to seal my bodgework so while it looks like a growth it does work (for the time being) and I can just take the tape off to reverse it. Do you suggest I just dremel the PSU brick open, or should I still try getting it apart with a flathead screwdriver (despite...

Update! I opened up my charger and swapped pins 1 and 2 (they were the red and orange wires in my charger). The computer now works, but I assume the battery will no longer charge. This confirms TechKnight's assessment (and what tjjq said from the beginning ;p ). So now I've got to just recap...

I've got a battery I've recelled, and it works, though the computer won't boot off it (especially now that I removed the PRAM battery :p ). Will the battery charge at all off the 2.1V VMain? I assume it'd be slow as heck if it did, but since I'm not the greatest electrical engineer (aspiring...

There's an interesting suggestion. :O So I guess that might be a temporary fix (it'll make the battery slow to charge, if it charges at all, though, I think?). Would there be a way to take the plug from the PSU and hook it up to a more generic power supply and get it to work? Maybe there's a...

I briefly tried, and it splintered a bit...  Any suggestions for replacements? Which caps should be recapped, or (if I steal the plug off the end) are there any other known supplies I can just splice the plug onto and get it to work? Edit: the computer should still work, right? Is it likely...

Alright, I've got the multimeter! ...I stuck wires into pins 1, 2, and 3 (not all at the same time - don't wanna cross anything). From 1 to 3, the current is 16.5 V... but from 2 to 3, it's only around 2.1 V. Something tells me that might be part of (if not most of) my problem, huh? Well...

Don't want to, but I'm willing to. :p I'll poke it with a multimeter tonight, either way.

Won't be able to get ahold of one until tomorrow night; that's why I ask. Evidently, there are two ground pins and to 16V pins, one at 1.5A and one at 1.0A. I remember seeing this info somewhere else on these forums.
