It could fry the battery or the electrical system on the vehicles
no- if you connect a battery the wring way round you will short the battery on a modern car you may damage the ECU
It means you probably fried the electronics.
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
check your main fuses
Sounds like dirty battery cables. Remove cables from battery and clean battery post and inside of cables. When these get dirty the resistance builds up an alt. Thinks battery is charged. After cleaning you may have to jump to start. Other cause could be the alt, and or battery
no as long as you don't put the cables on wrong
check your battery cables. could be old or just loose.
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.
