On the back of the 1928 National light switch, did the resistance coil have a type of covering on it?
What type of covering would it of had? a fiberglass wrap or just a cloth covering?
My resistance coil seemed to of had something on it, but it had crumbled away years ago.
What would be the best product for this application??

The resistance unit had some wrapping on it, but I don't know what it was. If you are restoring that resister I would take it to someone who has a kiln and ask them to dip it in their slip and then fire it for you. The covering is primarily to prevent a fire under the dash if something came in contact with the hot resistive unit.

Thanks AntiqueMechanic
I never even thought about that, my mother has a ceramic shop and pour's her own molds with ceramic or porcelain.
I will try the porcelain and see how it works, my only concern is that porcelain is fired at a higher temprature than ceramic, and I am woundering will the resistance coil handle the higher heat setting?
Is there anyone out there who sells new resistance coils incase things go wrong??
Have you tried this yourself??? What were the results?
Thank's again

I have a friend who has made some resistive units for a heater switch, so something is available. No. I have not accomplished such a fix, however knowledge of the system says there is a high degree of success with the process.

Hello Ray I like that idea. Never would have thought of it. When he gets the resister off the switch he could measure the resister and then find a high wattage resister of the same value or close to it that would work if something happens to it during the firing

How about coating with Epoxy. Seems to be a popular choice with circuit board builders. Dad useta build boards at work and after "bake-in" they would put them in a protective box and fill the box with epoxy and thats how they would be used. Would probably work good as a heatsink also.
Just a Noob here.

It was most likely asbestos of some form originally. I have seen something like nomex used on some things. On my car I just made sure no other wire would come in close contact with it. I drive mine some at night and have not used the dim setting much anyway. Dim is the only time that coil is used.

For a better headlight at night I converted the globes to 6 volt Quartz Halogen and ran a direct wire from the dim terminal to the globe. Works well for me.

Some say "Street is neat". I prefer "1928 is great" I have documented my 45 years with a 1928 Chev Tourer, from 1973 to 2018, and regulary add other items that I hope are of interest to others. Your comments are most welcome.The story of the Red Chev can be viewed at http://my28chev.blogspot.com/
