I was just finishing up on installing a CF hard drive in my 600 when I decided to run some aditional power to my Motherboard. I had soldered wires on the power connecter and ran it to the floppy power connection. I was running my CF off of a 40 pin IDE connection so I had to power my adaptor and I used a power splitter. I didn't have one so I made one out off a extra parts I had laying around. Connected the power cables with the CF adator in the middle and turned on. Nothing..... Took it apart and noticed that the red and black wires going to the CF card was connected to the yellow and black wires. BAD....I just toasted my SAN Disk Compact flash and now the computer doesn't run.
Is my computer dead or can it be resurected.

Ugh, doesn't sound good.... Others with more expertise may be able to help more..... But, you always want to check, and then double-check any power connections to any computer. Questions; why did you need more power to the 600 after adding a CF card? Don't they need less power than a comparable HDD? Second, couldn't you have used an old PC (AT) PSU to power the 600? (using a multimeter, and recyclcling the 600's PSU plug..... to make sure you have +12V going to +12V, etc. ??
Best of luck.... :)
OK, worse-case scenario... you might find A600 mobo's on EPay.....

I read that it helps with stability to run power to the floppy power connection. I messed up when I used the molex connectors from some old fans. The wires were correctly color coded but I didn't notice they were connected to the 12 v part of the molex plug.

I am using an old AT power supply to run things. I could never find a original Commodore PS .

If you ran 12 volts to 5 volt parts then something is burnt dead. Could you get a logic probe and test every trace coming out of all the chips?
-
Well if I understood correctly, that's what happened. 12V to 5V so most probably the CF card is dead. I wouldn't be so sure about the miggy though. They're resilient fokers :P
First of all check the CF card in a CF reader an in a PC (And check in disk management if the PC recognise the card physicaly)
Second, check via correct powering the miggy, (without CF adapter mounted) if Amiga starts up.
One last easy step, is check with a multimeter in continuity test, the +5/GND and +12/GND and +5V/+12V. If it beeps... then it's bad :(
Maybe people with more experience can help you better mate
Good luck

What other hardware have you got running off the A600 motherboard? Because I really doubt that any instability you might have running a stock A600+CF card is anything to do with the power supply. Maybe if you had an accelerator hanging off the top of the 68000 it might, but even then it's only a possibility.
Injecting power in through the floppy connector is only something I've heard of in relation to the A1200 which can run pretty hefty accelerators and graphics boards off the trapdoor slot, requiring significantly more power than the board was originally designed to supply.
As has been suggested before, try booting it with nothing else attached and see if you get any colours or the purple Kickstart screen...

GOOD NEWS!!!! I unplugged the floppy drive and now it will boot from the hard drive. I have the A600 motherboard installed in a A500+ case using an A500 floppy drive. I tried to install my A600 floppy but it won't fit in a A500 case so I took the floppy that wasn't working apart to se if i could fix it. I checked it out but couldn't find anything wrong so I put it back together; crossed my fingers and connected it up again. IT WORKS........... at least so far. I will probably source another A500 floppy to use as a spare just in case.
I guess I just burnt another of my Amigas nine lives. Got 7 more to spare.
The CF card is toast though. Thats alright though, I was getting a little cramped in 2 GB.
I have rewired my power connections correctly this time so there is plenty of power to go around. I hope to get one of the accelerators that they are working on over at EAB whenever they come out. (hopefully soon)

Using Svideo hack to run an 17 inch flatscreen monitor
Could I ask how you did a svideo hack on a 600 to get it to run on a 17" monitor?
-
Easily....
You put inside the A600, DJBase's SVHS adapter that is soldered in U12 chip, and then you take the signal and put it in an El'Cheapo SVHS to VGA box.
Alternative, you can get Amigamaniac's RGB to SVHS adapter (that plugs in Amigas 23pin RGB) and use it again with an SVHS to VGA box
-
I decided to hang it off the RGB port. That way I could move it to my A500 if I needed too.
