Reversed polarity jumpstart. -_-

[11LE]

Hey guys. Mother's motorcycle battery died while and I went to jumpstart it. I did it right the first time and got it started, but it cut off. I had the cables off already, so I put them back on and I swap polarities when I put the cables on the motorcycle. The battery was flat dead, and I saw a spark only when I took off the negative cable from the positive terminal.

So basically, I hooked the cables up correctly from my (engine running) Camry to my mother's motorcycle, with a dead battery.

Now, the bike shows no sign of life in the battery at all, and my car starts fine. Is the damage exclusive to only her motorcycle? Or should I be expecting some electrical failure in the near future?

Thank you all. Happy New Years!

I had my alternator checked out and it is working with good efficiency. Car is undamaged.

The bike suffered a blown 20A fuse. New battery was needed before I permanently put it 6 feet under with my mistake, so the new one is waiting to be strapped in.

Close thread please.

The car is fine. The motorcycle needs a new battery.

OP was lucky a battery didn't blow up.

Does motorcycle have computer control like a car? If it does, that computer might have been fried along with the fuse. If it's OK, get her a new battery and a battery tender wouldn't hurt either.

Just got the new battery put in, along with a main fuse. No ECU to my knowledge. Bike is fine, now.

Thanks guys.

Yea usually won't be too much damage. Everything has a safe guard against this type of thing. For example most hid kits u gotta flip the connectors bc the Cables are wrong(we had that today). Btw sent u pm bout exhaust.
