A job well done. Jay S. listened to me describe the problem then, explained how he would approach and diagnosis the problem with the circuit. He then started work. When he found a problem, he showed it to me and explained what was happening in the circuit to cause the problem. It turned out there were multiple causes. He thoroughly explored the situation and corrected another problem as a result.
This was the first time I called Mr. Sparky. As a result of the above, I will certainly call them again. Jay also was very pleasant to deal with.
