can it run on? i accidentally ripped one of the wires leading from my battery pack on the right. so now there's only 3 wires connected to the car and therefore only 3 batteries giving power to the car. i just wanna know if these things dont work in situations like this. cuz i can easily solder it back on but i dont wanna take it apart, solder it, put it back together to find out it's something else that's making it not work. so does anyone know?
