I recently had my car fixed at a muffler shop. They cut out a piece of broken seal, and replaced it with pipe. Two days later, my battery light and brake light came on, on my dash.
I replaced the battery, and don't feel it's an alternator issue. I think what may be the problem, is they loosened or knocked off the ground wire when repairing the muffler.
My SUV is a 2005 Hundai Tuscon. I would like to find out how to trace the ground wire from my Alternator to the frame of my car.
