I am putting a fuse block into my 52 Hornet and just wondered if I can eliminate the 30 amp circuit breaker. I would think it is not needed if all circuits have fuses.:)

    Thank you for that information, very useful. It is already 12volts and I thought it is a good idea to put in a fuse block to tidy the wireing and not have in line fuses. :)

    leave the headlights on the circuit breaker. Some dark night you may wish you had.

    Oh, I don't know SuperDave - I had a couple GM cars (56 Pony/57 Olds) way back when and those had the headlights on a circuit breaker. There were a couple of times the breaker overheated (or whatever) and the lights went out.

    Thrilling at 70 per on a narrow 2 lane highway at 2 in the morning. Reminds me of the song by Tom T. Hall, Me and Jesus - we did have a fervent conversation at the time.

    At least with the breaker the lights can come back on, depending on where the problem is. I'm with Dave.

    Eddy, Ken, Dave, Park and Alex,

    I got her down to 40 before the circuit breaker came back on and I was never so happy to see the light. Stay with the breaker. It might be a good idea to replace the old one with a fresh new one. I don't know if some deteriorate over time and loose their capacity but maybe someone on here does know.

    Maybe do all. I have every circuit on an ATC fuse per specific function, but the main power to the ignition switch, hence the fuse panel, goes through a circuit breaker to prevent frying the fuse panel or ignition switch. I would suggest a circuit breaker and not one of those in-line 30 AMP fuse inserts that use an ATC fuse. A had a fire because of one of those. I would also suggest a 30 AMP circuit breaker for the horn.

    Brumac, Napa sells the circuit breaker( CB)that you need. It is a 25amp Napa part # 782-3003. Once you remove the headlight dash switch, it's an easy self guided replacement. I do recommend a relay be installed. The CB works on a bimetal heat element. After years of heating and cooling off, the element gets hot and stretches too much and the circuit opens. The relay ,kind of, sends the current from the battery through the relay to the lights. Simply put the CB never gets so hot as to stretch out, because most of the current misses the switch . You will probably never need to do this again. Relay is about $35 and a couple of hours work to install.

    Thanks Ron,
    That was a long time ago with my old 50C6. The next day I installed a NAPA headlight relay and never had the problem again. Sometime in the past couple of years I wired relays into my 54 HSpecial when I went to 12V. My tired old eyes just love those halogens at night. At one time I had an aircraft landing light on one side of my 73 Olds. It was FANTASTIC but impossible to use in our semi rural area and I removed it.

    I don't under stand why you all are having troubles with your headlights. I converted to 12 volts 13 years ago and installed a new YnZ's harness and have traveled 139,000 miles so far and have never had any headlight problems, cross country with a lot of night travel. Never changed any parts on the wiring system, all still original. You people must have bad wires. Walt.

    Forgot, I use the new Sylvania Silverstar High Performance Halogen head lamps and it's day time when traveling at night.
