As bad days go, this is one!

So, I was working on my 3000D getting it ready for market since I don't use it and it should go to someone who would appreciate it.

Anyway, was trying to get the floppy to work and set a replacement drive on top of the currently installed drive and transferred the power and signal cable.

Hit the power button and accidentally brushed the replacement drive and it slipped and shorted out against the other drive.

Loud POP!

Computer died.

Pulled the power cord off, removed the offending floppy drive from it's precarious perch and disconnected all cords from it.

Reinstalled power cord and pressed the power button.

Nothing.

Nada.

Absolutely no signs of life.  Hard drive doesn't spin up.  No power LED.  No joy.

So, my question, before I start checking pieces out in other machines:

How likely is it I fried the motherboard?  Or did I (hopefully) just kill the power supply?

If the power supply is the only victim, anybody got a suggestion for a replacement?  I noticed amigakit has an adapter for using an ATX power supply, but has anyone adapted an ATX to fit in the 3000D case?

Waiting patiently for answers.

Well, fresh day, fresh outlook.

Checked the power supply fuse and as suspected, it was blown.

Just for testing purposes, bypassed the fuse with a bit of wire wrap wire and tested the power supply with a floppy drive attached.

No joy.

To make sure, tried again with a hard drive.  Same result.

It appears the power supply is in fact DOA.  Hopefully it didn't take an honor guard with it!

I see that amigakit has an ATX to 3000 adapter with switch for $20.61.  Has anyone done the ATX conversion on a 3000D?  If so, how much of a pain is it?

@vlabguy1:  The machine itself was fine.  However, the floppy was becoming a bit dodgy and I was checking out a replacement!

Just finished fitting a new fuse vice the wire wrap bypass and confirmed all voltages are NOT present.  Fact is, none of the voltages are what they're supposed to be.

As far as the fan, since it's 12V, that pretty much re-confirmed no good output voltages.

Will check out that auction and see what's what.

Sadly,in 20+ years of messing with amiga's i have seen this many times,its a sad thing.
I always plug in some power Y cables to extend power to keep stuff away from the machine. I have heard of one guy who dropped his drives into a 4060 accelerator and killed it.. ouch!

see if the fan spins up on the psu, if not the problem is in the psu likely.. you could also check with a multimeter. Hopefully it just killed the fuse.

good luck!

p.s. its possible to fit a microatx board in the 3000 case, but its gotten hard to find them with -5v,since it was deleted from the atx standard.

wow first check http://www.ebay.com/itm/Lot-of-2-Micro-ATX-250W-Power-Supply-P4-12V-/271701314452?pt=PCA_UPS&hash=item3f42a90b94
2 of them,supposedly new, check for sure, but magnifying the label i see -5v listed.
You might double check the model on the athena site to make sure measurements are actually the microatx.
 just FYI athena brand stuff is kinda hit and miss, ive had dead ones out of the box and ones that seem to run forever.

Well, I pulled the trigger on an Athena AP-MP4ATX30.  Looks like it has all the right voltages and is almost exactly the same size.  Will wait and see.

Guess we can put this thread on hold until the power supply comes in and probably after Christmas!

[curtis]

Got the Athena power supply in.  Talk about almost a perfect fit!  It's just a little taller than the original power supply.

Will remove the power supply board from its case leaving the bottom half as a shield.

The fan is the same size, so will move the new fan over.

Solder the power leads from the old power supply keeping the switch.

Transplant the new power supply with the bottom half of the case and wait for the Amigakit adapter plug!

Life is starting to look up a little.

Trust me Plaz, I hear you!

You did forget one thing to watch out for.  Smells!

When I was in the Navy, I made quite a few log entries of "magic smoke" escaped!

My supervisor, as a rule, thought it was funny but reminded me to maintain accuracy in the log entries for future reference!  

We have a running joke at work. Electronic devices are packed with smoke at the factory, if you let the smoke out, it won't work anymore. Customers are not amused.

Finally got the 3000 back on the workbench (actual physical workbench!).

Plugged the amigakit adapter into the 24 pin plug from the power supply, plugged that into the motherboard.

Hooked up the power cord.

Crossed fingers.

Pushed the power button...

It came up to the "Insert disk" screen!!!!!  

IT WORKS!!!!!

Power down, pull power cord.

Clean up power supply installation in the old case (yes, it fits).  Desoldered a few unneeded lines.  Resoldered a few dodgy looking solder spots.

Also, the amigakit adapter had a power switch on it that I didn't need since I was able to transfer the original switch over, so I clipped it off and connected the 2 lines to maintain continuity.

Reinstall new power board in old power supply case.

Add a floppy drive and power on.  Yep!  Boot screen comes up.  Insert diskette and boots right up.

Add the hard drive with floppy still in drive and proceeded to format the hard drive and do a fresh install of 3.1.

Worked like a champ!

Popped floppy disk out and booted from the hard drive with no problems!

Only bump along the way was when I started, I didn't hear the fan running and the delay on boot screen was so long I thought it wasn't working.  Tried another power supply and it worked with the same delay so tried again.  Yep, the newly installed power supply is working.

As far as the fan, the thing is so stinking quiet I didn't hear it.  It's running in stealth mode!

As an added attraction, there is a 110/220V switch on the new power supply, so I clipped a small hole in the old power supply case and mounted that so this A3000 can now go both 110V or 220V!  Switch mounted right next to the power switch.

Life is good once again.

And, as good days go, this was one!  Except for th 2-3 inches of the crappy white stuff that fell today and kept the temp down around 10 degrees Fahrenheit!
