One wire?

I went to replace my hall ceiling light in my 1974 Sovereign and found that there was only one wire coming out of the ceiling. I get the feeling from some of the other posts that the light has a built in neutral that grounds itself on the ceiling wall. And yet when I tried to hook up the new light that I bought at camping world, it didn't work. I hooked up the black to black and touched the white to the ceiling. Is there something I'm missing? Attached are pictures.

You are correct the light has 1 wire hot with switch on and return is through the shell back to ground! On the replacement you must remember that they sell those to people that own the fiberglass boxes sooooo the other wire on the new light goes to a ground on the shell put an eyelet on it and use a pop rivet. You can hold and try first touch the return wire to the shell.

The long tab on the mount provided ground through the inner skin which is aluminum.

I just checked the wiring diagram in a 75 service manual. Ceiling lights are grounded to the shell. The old light was working, right?. Have you tested the circuit? Could you have had a dead short removing the old light blowing a fuse?

Where exactly were you touching the white wire to the ceiling? It must make contact with bare metal, so try touching it to the inside of one of the screw holes. If it still doesn't work, the next thing to check to make sure you have 12 volts on the black wire.
