Just a question???????

[ShuuChuu]

I accidently bridged the 11v power input and ground on my dvd drive, and fried something. Is there something obvious that this could be?
I mean is directly connecting the power and ground going to cause an obvious problem???

Cheers in advance

If you mean shorting the power lead to ground of the power supply for

your DVD drive? That may have taken out a fuse link?
I'm not sure exactly by the way you have describe the mistake.

But if you mean something on the order of getting the polarity
reversed ? That could also cause lots of damage how ever, a good
unit would have a protection diode and fuse link before the diode
but then again, the plugs are suppose to be keyed so you can't
plug them in wrong.
Oh well.

As far as I can tell, doing this type of thing would only create a
short flash and a burning smell...

Could be

If it was shorted internally to the drive it certainly would do
something to the drive like blow a fuse.

12 volt devices often have an internal diode that will be forward
biased if the polarity is wrong - blowing a fuse - but protecting the
electronics. You don't mention that as a likely cause . . .

External to the drive it is less likely to damage it. It is possible
that the short would cause a transient and if removed while still
connected could cause a "crowbar" over voltage circuit (inside the
drive) to kick in shorting the internal supply and blowing a fuse.

Did you check to see if your short may have damaged the source of
power to the drive?
