Vacuum shuts off when the power-head is swiveled

There is a connector just under the light on the top of the head showing "Brush roll indicator". Remove the cover and make sure the white connector is pushed all the way into the piece. Dont pull the wires, just push on the connector.

They can be kinked when the head is engaged to run. Check those wires and make sure they aren't being crimped.
