By dead with the breaker on, do you mean that you're reading 120V at the breaker wire and you've at the same time reading that you don't have 120V between either hot and neutral or hot and ground at any of the switches and outlets?
======================================================================================= Originally, by dead, I meant the breaker was on but all outlets/switches were dead. I didn't use the tester to confirm that because things were plugged in but not on and the hall switch and bathroom switch have the inner light which can be seen when it's off. They were both off and I assumed there wasn't power.
BUT NOW.......I turned the breaker on and those inner lights in the switch were on. I metered the outlets and read 115v on all. Thus, I turned on the hall switch and nothing. That inner glow light went flickering and upon checking the outlets again, voltage was roughly 55 to 65v in the outlets. I turned the breaker off then on again and the inner switch lights are aglow and the outlets are reading 155v again. My conclusion is a bad neutral SOMEWHERE which is triggered when I hit the light switch and/or was triggered when I turned on an appliance (computer, tv, etc) when I had them all plugged in.
I'm wondering if it can still be in an outlet or switch. If so, I am considering the advice of purchasing a box and replacing all just for process of elimination.
