I have a 4 bulb Marx floodlight tower with no visible wires except on the back of the lamp holders. The power comes up through a tube in the middle and connects to two copper strips , each one going to two of the lights. The light on one side work, the other side is dark. However, if I almost lay the tower down, the non working lights come on.
I do not have any instructions, but the wiring is simple. There are just two connections on the base, one power and one ground.
I am pretty certain the problem is with the copper strips which go to the lamps, but I do not know how to fix. Any suggestions appreciated.
