Hopefully someone can help point me in the right direction. I recently acquired a c.1940ís Frigidaire refrigerator. It has a two prong unpolarized plug which has exposed wires in the plug so I would like to replace it with a grounded plug.
The problem I am having is I havenít ever done anything like this before so I have a bunch of questions.
First, Iím not sure how to tell which wire should be hot and which should be neutral. I found this website:
Which said that the one which is common with the outside of the light bulb holder is neutral. However, it also said that the part of the cord with ribbing is neutral. In my case the unribbed one is common with the outside of the light bulb holder. Does the fact the fridge is so old explain why that advice doesnít work? How should I determine what the neutral wire should be?
For the grounding, what is the best way to ground the fridge? My multimiter isnít showing any conduction between various parts of the frame, although that may just be from rust. Iím planning on just drilling a hole into the frame for grounding, does that sound good?
I am planning on cutting the current wire and splicing together with a replacement beyond where it is attached to the fridge. I canít access the junction box under the fridge easily. Is this a safe way to connect a new wire or should I try to get to the heart of the electronics?
Any other advice or hints or things I should know before embarking on this project? It doesnít seem to hard to me, but should this be something I should have someone else do for me?
Thank you very much for any help at all!
