I noticed one day that the pump wasn't coming "on" when our power was out and, with some tests, it looked like the converter had died. The way I understood the setup was that the battery/converter was plugged in "between" the wall outlet and the pump, so that the pump would run normally most of the time (power running through the converter still, just not using it) but then the battery would kick in when the power went out– so no human intervention required it ran normally most of the time, then used the battery when needed. The previous owners of my house had an AIMS PWRIC1500W converter and battery hooked up to the sump pump in the basement, in case of a power outage. If someone could help me I'd appreciate it. I am sure I am just overlooking something silly. Easy enough, and I have one, but the wiring diagram on it shows a straight run from the transformer to the button. However, when I wired it like the diagram shows me the chime buzzes electrically. I have located wiring diagrams for it and it sort of makes sense. I have toned out the wires with my tone kit and they are all fine. There is a second 2 conductor wire going from the chime area to the front door push.

There is a 2 conductor wire (black and white wires) going from it to the chime area. The wiring for the doorbell is like this:

I am not sure of the age of the town house, but I think it was probably built in the late 60's. We are moving into a new townhouse and the doorbell was not working when I tested it. I apologize if this question has been asked before, I did search but could not find a situation like mine.
