So last week i was cutting down a small tree with an electric chain saw. I was in a tough spot and the chain saw stopped working. I couldn't find any breakers blown, so i switched to another outlet to get the job done. Our outside fridge stopped working (we noticed the next day) and our electric tooth brush stopped charging as well (noticed about a week later). So at this point we have three outlets not working, let's call these three outlets the Front, Back, and Bathroom outlets. So, I started to investigate. Here's what I've noticed:
For brevity, i'll use H as hot, N as neutral, and Gnd as ground.
Bathroom - H to N measures ~0V, Gnd to H measures 120V, Gnd to N reads 120V
The Front outlet and the Back outlet measure the same. Removing the outlet from the bathroom there are two sets a wires coming into the box. I'll call these the Incoming lines and the feed through lines. If i disconnect the feed through lines from the outlet I get the following
bathroom: incoming H to N: 94V, incoming Gnd to N: ~17V, Gnd to H: 120V, feed through Gnd to H and Gnd to N: 0V
Front outlet: 0V everywhere
back outlet: H to N: 94V, Gnd to N: ~17V, Gnd to H: 120V
The 17V from ground to neutral seems really high to me. and it seems like i'm loosing 10V or so between hot and neutral (120 minus 17 = 103 not 94). I tried plugging a lamp in to both the Back and Bathroom outlets at this point, and it wouldn't light up with either (tired with LED and incandescent bulb). a small fan wouldn't work in either of these either. I would have thought 94V would have been enough to start the fan or the incadescent bulb up at least.
If i flip the bathroom breaker, the back outlet (and the bathroom) go to 0V everywhere. It seems weird that these would be on the same breaker... but I don't trust this houses' electrical stuff to make sense from past experience. Below are some pictures to maybe help clarify somethings.
It should be noted that all the outlets were working about a week ago until the front outlet died from the chainsaw being used on it.I took a look through the attic trying to see any breaks or shorts... but it was hot and most things were covered in insulation, so I didn't really see much.
I flipped on/off all the breakers, but the bathroom breaker was the only thing to cause a change in the front or back outlets.
Any ideas what could case this, or where to look next? I'm a bit stumped at this point. I can flip more breakers on/off if needed. Thanks for any suggestions!
