Question about wiring and voltage with switches and lights
You should have 'whites/neutrals' in the outlet boxes.....it's the only way you could possible have 110 volts at the receptical! And you might have 'whites/neutrals' in the switch boxes.....is this what you are refering to as a "switch panel"?? In the Electrical trade a "panel" is box with breakers or fuses in it.....not being picky here, just looking for clarity. Yes, remove the recepticals and switches and look for a broken or loose wire....either a "hot" or a "neutral". Somewhere you have lost one side or the other...either the hot or the neutral... As we can't see what you are working with, do the wires for your recepticals and/or your switches terminate UNDER the screws????? OR....do the wires terminate into a hole in the back of the recepticals or switches, like a PUSH-INs??? I have seen lots of cases where the push-ins become loose, wear or lose the spring tension and the 110 volt circuit is lost. We would go trouble shoot these by making sure the light switches were switched "on" and then go around to the near-by receptical and wall switches and pound the wall areas there by vibrating the loose connection and MAYBE the light would flicker and find the loose connection this way. This is not easy for the novice.....hell, it isn't easy for some pros! So, if you countinue to try, and keep us posted, I/we will keep trying to help you. This IS the learning curve or school of hard knocks. Hang in there buddy.
