| Post subject: | Headlight circuit breaker |
Where is the circuit breaker for the headlights located on a 74 Duster. Run my headlights for about an hour and they will shut off and a second later come right back on. Nothing else goes out, just the headlights. I think it could be the circuit breaker. |

The thermal cutout circuit breaker is built into the headlamp switch. A new headlamp switch will probably fix the blinkout symptom, but to fix the root problem and get much brighter headlamp light, put in relays. |

I just replaced the headlamp switch. Will look into the relays though. Is this problem common on old Chryslers or is my wiring about shot? |

A lot of cars, old and new, have serious voltage drop in their headlamp circuits. |

Here is some info. I have converted one of my Studebakers to dual realys, it has poorly designed switch to begin with, age don't help. Big difference. http://www.madelectrical.com/electrical-tech.shtml http://danielsternlighting.com/home.html |

I'm not saying this 'cause the second link rrither posted is my own site, but to provide warning: The madelectrical site's headlamp relay method is halfåssed, and there are accuracy problems with most of the other articles on their site. |

Dan, I just had a brainstorm. The previous owner put a set of Halogen headlamps on in place of the sealed beams. Do Halogens pull more than sealed beams? If so, I think that might be what is causing my circuit breaker to trip. I have a new set of sealed beams ready to put on the car. |

No, the halogen sealed beams, the regular sealed beams and the replaceable bulb H4 type units all use within a couple watts of one another. Essentially the same (the exception being replaceable-bulb headlights with overwattage bulbs, that is, higher than 60/55). The switch breakers DO get soft with age, and the wiring resistance DOES increase with age. Don't downgrade the headlights to mask the symptom -- fix the problem! |

I just changed my headlight switch about a month ago because of the same problem. Is the best thing for me to do is runn some new lines from the switch to the lamps. |

No, the best thing for you to do is to leave the factory wires alone and install relays.
