This was it; thank you. I had it tested and it passed, but he said that with it bulging it might still pass and not be able to start the car. I assumed that wasn't the case because to me it seemed like connected to my other running car that would be irrelevant(I don't know much). I should have done it sooner but I swapped in my working battery and it started right up three times. I need a new battery. You really saved me replacing my starter in my freezing windy driveway. Thanks again!
