  • Argg. On an older car you could have just killed the voltage regulator. Of course this all depends on the make and model of your car. Newer cars have computer chips on them that could get fried. You may have to have your car put on a diagnostic machine to find out which code your car is displaying. Sorry and good luck.
  • Yup, you've possibly killed your car. If it's a modern one with electric/electronic everything, and if each module doesn't have reverse-polarity protection (cheaper option to manufacture) then it's goodbye innards. Was there a hefty spark when you connected up? Whichever way, I'm afraid this probably won't be cheap...
  • If your lucky, you blew one or two main fuses. What make and model car is it? I can steer you in the direction to check. If your not lucky you caused big time damage....
  • some vehicles will not allow an improperly connected cable to affect them... but most will short out..at least the battery if not major electronic components in the car. hopefully its just the battery. batteries dont like being shorted out. most vehicles, nowadays, have a fuseable link(replaceable) that will burn out to protect the vehicle. usually in the cables or near them
  • thats what happened to my car. its a 1960 ford falcon, do you guys think it just might be the wiring since its an older car
