Circuit breakers or dropping resistors?

[IMG]Instruments.jpg[/IMG]This is not the original dash from my 6 volt '53, but the "new" one I'm going to use. Are these thingies out to the side dropping resistors to use with a 12 volt system or circuit breakers? Seems a funny place to put breakers...

Please see gallery if pic doesn't show, still figuring that out...

I had the same units on my 51, I think they are the 6V constant voltage regulators. I junked them went to NAPA and purchased a 12V constant voltage regulator for a mid 60's F-series pickup and my gauges work perfect.

Hope this helps

Yes, they are your circuit breakers. Check with the search feature, I remember someone explaining that one is for headlight circuit, and one is for the remaining circuits but I'm not sure. Jeff.

Voltage dropping resistors or circuit breakers???????

Break the tie!

I'm working with a dash for my '53 that is not the original dash from my 6 volt '53, but the "new" one I'm going to use. There is a "wing" on the left side that contains two little components labeled Fasco Type 1110 with Batt on one side and Aux on the other. The two "Batts" are strapped together. I went to NAPA to check on voltage dropping resistors and they look a whole lot like these, but some have said they are circuit breakers. I see very little if any resistance through the devices with my ohmmeter. Are these voltage dropping resistors to use with a 12 volt system and 6 volt guages or circuit breakers? Seems a funny place to put breakers and the responses disagree so far...

Please see gallery for pic, can't get it to place in the post

I have the same thing on my 6 volt stock 48 instrument panel. The electrical diagram calls them circuit breakers.
Per the Manual: "One of the circuit breakers prevents overload of the headlight circuit and the other prevents overload of the balance of the lighting circuits."

These are bimatelic switchs that when heated bend and break the circuit, when the cool they will reset themselves.

I broke down and dissasembled one. It is indeed a circuit breaker (which I don't need since I'm going with a fuse panel). You are absolutely right that it is a bimetallic strip (rather attractive design, not pure function) with a set of contact points. Anybody need the wing and two breakers? (one breaker a little bent around the edges...)
