I recommend El Cajon Auto Electric. Family owned and operated, specializing in the worst problem a car can have.. electrical

My alternator was having an intermitent short... and then it would fry the wires from the ignition switch to the alternator. I'd replace the wire, test the alternator, and it tested fine. So i couldn't find what the problem was. I'd drive the car for a month and then it would happen again. Tom and his guys found the problem, and fixed it. Done, no more trouble. Love these guys.
