My central vac is not working from any outlet. I posting here which led me to the problem. The wires are disconnected at the unit. There are 2 wires coming from the unit and there are 3 wires coming out of the wall. When I shot the wires on the unit the vacuumm starts. I tried to connect one of the 3 wires to the 2 wires from the unit but the vacuum run contniously and I see a blue spark in the unit.
How do I connect the wires? Thanks,
