Scary electrical wiring.

I knew the electrical wiring in my house was sketchy before I bought it. The inspector said the wiring from the breaker box was under gauge. Something would come on, and stuff would flicker on the other side of the house.

It makes UPSes grumpy. This morning my computer and new UPS was off, as in completely drained I guess. First time with this UPS.

When I got to poke at it more this evening, I noticed that, with everything else in the house off, the UPS was refusing to use wall power, and saying it was getting 145 volts. Up to 150. I noticed a weird buzzing elsewhere in the house, and tracked it down further. Very basic ceiling light fixture in a closet. When I turned the light on, the buzzing diminished. I found the breaker for it, and flipped it off. UPS said input came down to 107 volts, and was wiling to use it again.

Ick. Looks like my computer needs a new power supply.

Electrical update.

I left the breaker with the weird buzzing off.

This morning the filter for my fish tank was not running. Turned out that the APC surge protector that it was plugged into was blown - soot around the socket it was plugged into, and on the prongs. Plugged the filter directly into the wall and it worked.

UPS was fully drained again, and unwilling to use wall power, and reading 89 volts input.

Anybody have a multimeter I could borrow?

I'd like to determine wheither my electrical problems are in my house or from the street.

And I have nothing better to do until Monday morning than to pick one up frome somebody.

Hints on where to find mine would also be appreciated. Little, yellow, grey plastic case.

If I don't get a better offer by the time stores open, I'll have to buy my own, and I'm interestd in recommendations. Mybe a fluke 115? My house does need to be rewired...
