headlamps fuse ?

[rusty eagle]

I trie to bring the wiring of my '79 cherokee back to original ( after 4 previous owners)and I just can not find the headlamps fuse.

I assume that it is in the fuse box onder the dash, but when I take out all the fuses my headlamps still work.

i don't think there is a fuse for them just a fuseible link somewere.

Thanks for your quick reply steven ,

But according to the haynes manual there should be one (a fuse), but I there is not a clear picture, or diagram of the fusebox in the haynes manual.

Does anyone have a picture, or diagram of the fusebox ?

iirc it is a circut breaker in the fuse panel

[rusty eagle]

I am afright there is not one in my '79 cherokee.

But it could be that parts of the wiring have been changed for the eurpean market, but then again, i assume that there should be a fuse in the circut.

Does anyone have a picture, or diagram or can give me a direction in what part of the fusebox the fuse should be ?

The circuit breaker is built into the headlight switch.

I will go over to the garage right now and check this Lou.

I don't think so , I can't find anything on the switch that looks like a circuit breaker .

there is a small button on it that could be something like a reset button , but I have never seen reset buttons on cars (in houses OK), and I can test this button with a short circuit but I am afright that I need a new headlight switch after this

Does anyone have experience with headlamps fuses ?

I'm pretty sure there isn't a fuse. The headlights are extremely important so I doubt Jeep or any other auto maker wants someone driving on a dark road in the rain the suddenly the headlight fuse blows. My 89 doesn't have a fuse for the head lights.

[rusty eagle]

Well it makes sence in the way you put it there Steve , it also makes sence in the way that I find melted wires (probebly due to a short circut).
The reason I put the question on this forum is that I am prety sure that "other cars" do have got a fuse for the headlights.

So I just want to be realy sure before I put in a fuse in the suply wire and find an other (original)fuse in a place that I havn't found yet.

Well, I just looked at the wiring diagram in my Haynes manual and the headlights are not powered through the fuse block. It goes straight from hot to the headlight switch and shows a circuit breaker in the switch then to the dimmer switch and then the headlights. A fused source does go to the headlight switch too but that's for the parking lights and tail lights only.

I'm not trying to be condasending, but most if not all cars DO NOT have the headlights fused through the fuse block and for good reason.

You have a problem with your headlight switch or some wiring, it's not a fuse problem.

uhhmn, every bug I ever owned and my BMWs headlights are fused in the fusebox. But maybe that's a German thing. Or maybe not having one is a Jeep thing

Lou,

I think you are right afterall ,there is another post on this forum " Headlight Circuit breaker " that is about the same problem .

their solution is that there is a Circuit breaker in the headlight switch (like you said) that resets itselve when it cools down again.

This is new to me , and would realy like to try this ,just to be sure, but I will not, because I am chicken , or should I just do it, or not , well...... let me sleep on this

[rusty eagle]

By the way , you were also right steve
