The Stovebolt Site Forums The Shop Area The Electrical Bay Horn amperage and sound for 37 half ton

Two horn questions:
1. Would the original horn on this truck have been an "a-hoo-gah" horn?

2. About how many amps would a 12v a-hoo-gah horn pull (the horn I have I estimate is about 25 years old).

Thanks,
Mike

the type of horn you're thinking [like this, "Klaxon"] was aftermarket and primarly found on 20's & 30's Fords, 6 volt - no doubt there are Klaxon repros around in 12V, but current draw would be unique to the particular item you have .... always a good idea to use a relay for a horn regardless

1. no. solid tone horn.
2. amp draw about 7-10 i think. most horns used a relay. i suggest you do the same.

consider using what you have as a backup. horns back when were not made for high speed vehicles.

Thanks Bill and Koolkar. I will definitely get a relay in the near future (I keep blowing the horn fuse). As for horn sound, I'm probably considered a purist on most things regarding my truck, preferring everything to be stock or to look as much like stock as reasonably possible. But people really get a kick out of my ah-hoo-gah horn so I will keep it even though its not the original sound.

Your '37 should have had a single horn mounted to the manifold. Single horns didn't usually have a relay. The accessory dual horns did use a relay. I don't remember what size fuse I have for my dual horns, I can go look if you want that info.

Thanks Tiny. No need to look for fuse size, I'll just use the size recommended for the relay.
