| The neutral wire is probably reversed with the hot wire, so that the screw shell is live instead of being the neutral, and the screw shell is shorting out to the frame of the lamp.
The neutral should be the larger blade on the plug, and should be the ribbed or striped wire on the 2 wire cord, look closely at the cord and you should se one wire is marker. This wire should be connected to the screw shell of the lamp socket.
I any case, the insulating material between the screw shell and the brass outer shell/housing is not insulating any longer and needs to be replaced, most likely.
Or could be the cord itself is just shorted out to the frame of the metal lamp.
The short answer is no a 3 wire adapter will not serve any purpose, and the lamp needs to be taken out of service and repaired, before someone gets hurt. |
