    hmmm
    what power supply WAS it...
    it might be just a few blown components, or most of them..
    where did the spark come from??

    hey muki
    It would be helpful to identify your problem if you could post a pitcure of the PSU component side .... also use a multi meter and check the supply for broken links ...

    might help ..

    u probably would have blown the fuse in the dc-dc...

    i connected my amp up the wrong way once, had a big spark, a bit of smoke, but luckily all i damaged was the 2 30 amp fuses in the amp

    unfortunally, reversing polarity is still number one cause of killing electronics.
    thank god that manufacturers know this and in most cases it wont kill your things totally.
    you most lightly killed somekind of protection in the circuit somewhere

    you probably either blew a fuse or blew a diode.

    it sparked right at where you put the neg. and pos. wires. Im going to use a voltometer to find out which wire is pos. and connected it directly to find out if its totally dead.

    ok...i found the neg. the psu still doesnt work. I also found the fuse on the psu, its fine. The dc-dc is from ICP Electronics, model ACE-865V Dc input: 8v-16v===15a
    dc output: +5v==6a
    -12v==0.5a
    +12v==2a
    -5v==0.3a

    thanks you guys, you have been a great help, any suggestions, or anything else that could be the cause of it....anyone want to buy a DC-DC psu...lol
