Hey, so one day out of the blue, I attempted to start my car, and it only clicked 1 time. Got out and knocked on the starter then started right up. That worked a few times and then stopped. Replaced my battery, worked fine until another 1 click. I tested the connection with a test light and my car is pulling 12 volts when the car is off. Had the mechanic replace the starter, thinking it was faulty. Worked fine for a week and then today same 1 click. The only way around this issue is to unplug the positive terminal every time i get out so that the battery doesn't drain. Please help me guys!
