Battery cables reversed.

If the battery cables are reversed just long enough to make the spark (1
second) what are the consequences? Is there a fuse fusible link that
is suppose to burn out?

Are there items that might of been damaged? If damaged would it be
immediate? Are there items I should check?

Thanks

That's just enough time to destroy anything electronic on the car. The
only thing to do is to connect the battery correctly, and if nothing
smokes then test everything. USUALLY people get lucky and little or no
harm is done.

Murphy's fifth law of electronics states that A $400.00 part will always
sacrifice itself to save the life of a $0.25 fuse.

But maybe you came out OK?

I think Hammacher Schlemmer company www.hammacher.com sells some
sort of computerized smart battery jumper cables.You can't hook them up
wrong.Best thing though,just be extra carefull and never hook up any
battery jumper cables wrong.I once read about a ''trick'' many years
ago.A guy out in the boonies in cold weather,his battery was low and no
one around to jump his battery off.He hooked up his battery cables to
the battery and the other end of the cables,he touched them together a
few times.That warmed up his battery enough so that his vehicle cranked
up.

You can get the same effect on a "low" but not "dead" battery by putting
the headlights on for a few seconds. Of course you don't get the cool
sparky sparky action.

That's assuming there's no battery installed. If there's a battery, the
voltage won't go negative. The battery will explode and the battery cables
will melt before that'll happen.

I once ran my battery down so far that it wouldn't start. I noticed
that I had left the lights on when I went out to get my lunch at
noon. I was parked in the shade, so I rolled the truck out into the
sun and it started right up when I left that night. Some times you
get lucky.

The OP didn't explain what "battery cables are reversed" means. Was he
attempting to jump the battery incorrectly or was he installing the
battery incorrectly?

you can fry the alt.
alt. has dioles that allows the currant to flow in one direction.
when you reverse that current you short them out, and they blow.
and your alt. will not work. it may work a little but not enough to
carry the requirer amperage.
the diole can also cause your batt to go dead if it shorts it self out.

the same gos for the regulater'
believe it or not it a fact. ps. it can damage the computor also
