high beam fuse
my high beam fuse took a crap on me and im wondering where i could find another one. i went to radio shack, nothin, advanced nothin, all other auto parts places, nothin. i dont want to get it though ford and get screwd for $15 (not sure if that is the price but probably close) for a 35 cent part. also it is 3 amps right?

not at all, my fuze block looks fairly new so it might be aftermarket but i have no high beams and on the fuse block there is a place marked hi beams and the fuse is clearly blown. my regular lights work, but the high beams dont. its a really small fuse. i havent been able to get it out yet, i stopped tryin after the piece of metal i was useing sent sparks flyin but some how i didnt get shocked. from what i can read on it it says 3A, ill go take a look at it and update when i get back in.
update: after another shower of sparks i decided to give up again, it was hard to get around under there and hold the lighter on at the same time. so i decided to draw out a picture of the fuse block. about it saying hi beams, it doesnt but i have tested and when i turn the lights on both sides of the fuse under the blown one become hot and it makes sence to me that the one above it would be the high beam fuse because it is blown and i have no high beams. on the picture red is the blown fuse and gray are the 2 open spots on the block. https://www.ford-trucks.com/user_gal...110027&width=0

Heres a crazy idea, before you start doing anything disconnect the battery, and get a flashlight. The fuse might be the control circuit for a relay for the high beams. Not sure why it would be wired this way if it is aftermarket.

A 3 amp fuse? OK. That figures in to a relay system like in this article.... https://www.ford-trucks.com/article/...r_Brights.html .
Try tracing the headlight wiring back from the bulbs & maybe you'll locate relays.

You know, if anything, if it was marked 3A on the fuse panel itself, I would say that it was meant for the indicator lights on a replacement dash and aftermarket turn signal switch. The 3A is also suppose to feed the turn signal indictors on the dash and aftermarket turn signal switch (they have little arrows that light up).
If you still have a stock head lamp switch in a 1976 F-150, as Mil1ion has already pointed out, the circuit breaker is in the headlamp switch. If it is bad, it will cause problems. Good news, it is only about $10.
If your high beam switch is on the floor, make sure the switch is not bad, if it is not bad then make sure it is not wired to that 3A fuse

I hope you get it fixed. I guess this is one problem associated with non-stock or aftermarket components. I would try to figure out what you have so you can get a better handle on getting parts for it. Do you think it's aftermarket or a fuse box from some other type of factory vehicle?

i really dont know what it is, i would have to see another truck to tell if it is after market or original. it looks too new to be the original that came with the truck but someone could have replaced it with an oem part.

I have to agree with Dennis in a previous post higher up on the page. The original factory set-up did not have fuses for the headlights. They were hot wired directly to the switch, and then to the battery. The only protection was a circuit breaker inside the headlight switch. So you definitely have something different there.
