Ford specified a 20 amp 3AG glass fuse

The original part (01A-12250) was a breaker assembly for the lighting that had two sections, A 15 amp for all but the headlights, and a 30 amp side for those. This was used from '33 thru '48 in various configurations, and had the ignition resistor as a part of the unit.

Supereal, The 01A-12250 fuse block didn't come out till 1940 and most likely had different fuse requirements than the earlier units. The 48-12250 fuse block was very simple (crude) and only included a fuse and resistor. Here is my image frome the 1935-36 Ford Book. Regards, Don Rogers Author 1935-36 Ford Book

Thanks Don. I was going by the green book, which shows several types of the "breakers" for cars and trucks after '32, as do my books of wiring diagrams, and I stand corrected. From your pic, I can see that the "breaker" shown is, as your picture shows, the back side of the strip. Apparently, the term "breaker" is interchangable with the term "fuse" at Ford. I still think 20 amps is a bit low for the headlights when coupled with all the rest of the lighting system. I'd use a 30 to be sure, in any case. We replace the "breakers" in most cases with push button reset modern breakers mounted up high on the inside of the firewall. For those planning to install a fuse or breaker, don't fuse the charging circuit. If you want to be sure that old wiring does't set your car on fire, add a master switch on the battery post.
