Ford Focus • Alternator replacement

“Joseph was outstanding! I had an appointment between 10am-12pm. Joseph was very punctual by showing up at 10:05am and was finished with the car by 11:00. He installed a new battery and checked all electrical systems to make sure that the battery was the issue. He and his helper both shook my hand when they arrived.
If I have future automotive issues I will only use Joseph from now on.

Mc Son Autos

Surrey , 10 years of experience

“Rob did a a very good job in changing the alternator and fitting the belt. Alternator seems to be working, producing 14 V or more, but battery light stays on. Rob checked the resistance of the cable from the alternator to the fuse box and then the positive battery terminal, which appears to be OK, at less than . 5 ohm. Battery is good. The light staying on remains a mystery at this time, but no complaints about the work that Rob did. Certainly friendly and knowledgeable. “
