So yesterday I had my helper take the battery from the charger and put it in the battery box. When I got to the jobsite I plugged the wires in how I am used to plugging it in out of habit without looking at which side was positive or negative. My helper put in backwards and I should of checked it. My question is even though I plugged it in backwards the pump still worked fine while being wired wrong and luckily it didn't fry the pump how did it still work?
