Different vehicles have different wiring systems, and what got burned out would depend on where your starter cable were. All things dependent, it could be the ECM relay which gets fried, the ECM itself, chassis nodes (if present), etc.
It could fry the battery or the electrical system on the vehicles
You probably are going to have spend money fixing it.
if you put jumper cables on the wrong way you WILL kill the battery then if you leave them on you will cause the battery to overheat and swell then will u least expect it, it will blow up.. it will be a miniature hydrogen bomb
You can still fry some of the electronics just by putting the cables on wrong.
well if you really hooked up jumper cables wrong and you got by the fireworks show then you probably damaged your alternator and battery. Possibly blowing fuseable link,but if car runs then alternator and battery.
ALOT you probably just burned up your whole ignition system way to go!!
You probably didn't do much damage. You could of blown some fuses or damaged the battery.
Battery or battery cables would be the first thing I would look at.Battery or battery cables would be the first thing I would look at.
were did the tow truck hook the cables at ????????
If the jumper cables were hooked up the wrong way by mistake on a 1997 Grand Cherokee Laredo 5.2L, it might be necessary to check the alternator to make sure it is turning in the right direction. If the battery is still being charged, the vehicle should be fine. A high idle could be a problem with the EFI or Electronic Fuel Injectors.
You could've blown a fuse or even worse fried the computer. Check all fuses under the hood and the battery itself. Good Luck!!!
You blew the voltage regulator. Depending on the model, it is either a separate component or located inside of your alternator. Based on your problem, I would guess you need a new alternator. Replace it and your car will be fine.
