My lights dim when the AC comes on. I called the power company out to
check the connections. He checked the meter and I checked the panel.
He told me a story about a service call that was interesting. He said
he went to the call and the customer said when they flushed the toilet
that his security light went out.
The problem was found to be the well pump was causing enough drop that
his HID security light would go out.
Pretty funny story that I am sure has been told more than once, but I
wanted to hear it again.
