Joe;
When my ’48 had the same symptom of the headlights cycling ON-OFF it was to be sure the circuit breaker. While I was researching the characteristics of a thermal circuit breaker I ran into some information.

First: I found a comment that once a circuit breaker begins thermal cycling, and the load is not removed, then subsequent cycling will degrade the point set and the cycling will occur at a lower current. Also that same source included a warning that the circuit breaker would have about a 50 cycle life with the overload condition.

Second: DelCity has replacement circuit breaker for the ’48 design, and within their product offerings is a page of technical specifications. I’ve included a PDF file that contains those specification. There are two curves that describe the influence of the environmental temperature, and the time delay as a function of overcurrent.

Given the first comment perhaps you should ensure the contact set is free of oxidation, and if there is any some effort should be made to restore the cleanliness of the contact set. Also if you do find oxidation do not adjust until to prove the headlight load will cause a ‘trip’. When you test that switch/circuit breaker try to replicate the same orientation as it would be in the car.

It would be nice if the 48 and later independent breakers would be an easy retrofit. Could be done with some work but mounting and current path would need to be figured out. Also would have to remove or bypass the existing breaker mechanism built into the switch to do it.

If you put in a pair of these bulbs, I'd bet that your breaker would never trip again unless there is an actual short in the wiring! They're made for 6v positive ground but also available in 12v.

Thanks for this information, David P.
I appreciate the offer flackmaster (I have two old ones --with loose rivets on a couple terminals-- to play with)


1. I'm going to keep the charger on the battery, not start the car, turn on the lights on high beam and time how long it takes for them to go out. Let it cool.

2. Then I'll try it with both new heaters on with lights on and time that.

3. I'll cut off the battery and clean the contacts and retest the above.

4. Depending on results, I'll twist the screw (could be kind of rusty but I can try it on the broken light switches first). Then re-time 1 and 2.

5. I might drop $250 for the LED headlights, Don. Probably worth it to me anyway since I drive so much.

Thanks again

UNDERSEAT HEATER

I could not make the breaker relay open again. I ran headlights, heaters, fog lights for a half hour. More investigation in order. Running the engine may make a difference.

Some of this repeated earlier, but now it's all in one place. My original heater defroster motor had bad bushings and the rheostats on my paddle switch were shot. I acquired extra switches on eBay and sent them to Precision Power to be refurbished. I had the motor rebuilt locally at Auto Battery & Electric. Convertibles are cold and the windows fog up. Before the motor was fixed, the defroster couldn't quite keep up on some mornings. To get more heat, I started looking for a Dual Stream under-the-seat heater.

The Dual Stream under seat heater was first introduced on 1940 cars and positioned under the passenger seat. I found one for parts really cheap. I had the radiator component checked and it was good.

I had the whole thing de-rusted by soaking. Used primer filler on the top and painted it. I had the motor rebuilt at AB&E. The bottom pan was shot completely but I was able to use it for measurements to make a mechanical drawing in Adobe Illustrator (my turf in advertising) and convert it to an AutoCad file. A local steel fabricator laser cut the sheet metal from the file and another shop formed it to match the original. They reinforced the cup that the motor sits in with a metal wrap and reused it.

The heaters are set up in series. Included are pix of the hoses top side and where they run under the car.

When both heaters are on it is so toasty warm. The Dual Stream does blow heat forward and back. It really works. I will post pix next. I have to work on them.
