Receptacle load voltage drop to 10 vac
You May Have a Lost Neutral
If voltage only goes down, that is an indication of overload. But when voltage goes up in one place and down in another, that is an indication that your neutral is not working properly. Since you show 0V neutral to ground, the problem is very likely outside your home. In other words, a utility company problem.
Since you have a multimeter, one more thing to check:
If you have any 240V plug-in appliances (e.g., electric dryer), check the voltage at the receptacle. You should have a consistent value (~240V) between the hots and a nearly identical value (~120V) between each hot &amp; neutral. Then see how that changes when you turn on any relatively large loads (like coffee pot or toaster). If you see a similar change - i.e., one side up, one side down - then that confirms a likely neutral problem.
CALL YOUR ELECTRIC UTILITY
Tell them you think you have a neutral out. They should treat this as a serious problem because of the problems it can cause. They should send someone out fairly quickly to check things and, assuming the problem is on their side (pole or meter) they will generally be able to fix it pretty quickly. If they determine it is not their problem then you need a licensed electrician to check from your meter to your breaker panel and figure out what is going on.
Meanwhile, I highly recommend you unplug any sensitive electronics (computer, TV, etc.). While many devices are able to handle a wide range (e.g., 90V to 240V), many can't and even those that can may not like the ups &amp; downs.
