Mike, I iwll do that this weekend. If the other breaker holds, then I know the original breaker is bad and will replace.
What do you suggest in the "other" breaker trips as well.... that means there is something else going on.....
I have several meters that can be used to test the circuits out.... would they be useful?
Mike, Thanks for your help. I retraced all the circuits as you said. Finding power at all junction, I then traced it to the problem area. I saw where the power was connect yet the previous owner took out the photo sensor so there was no power feed to the leg going to the lights. I tested this with a jumper and the lights went on. I proceeded to buy a photo sensor and voila, the lights go on at night. They were on a different circuit. Now I have to trace the other circuit that is tripped. Thank you. David*
