Driving when suddenly headlights started to dim, radio got fuzzy and went out, gauges all went down. Eventually I pulled the car over stopped it and it shut off. Then next day changed the alternator and battery, and charged it up to start. Drove it for about a week until the same problem happened again. This time I changed a ground that could have been faulty ( it was rusted and corroded). Once again charged it up and drive it for a few days. Finally changed the ignition switch and charged it up. But as soon as the jump pack is pulled of the car it begins to have the electrical failure. Now the car will only start with the jump pack on. Idk what else could be the problem???
