Fuse replacements

[Merc123]

I'm curious. What would happen if I replaced every available blade fuse in the engine and passenger compartment with 30 or 40 amp fuses? Would that hurt them at all?

Would that hurt the fuses? No. But the point isn't to protect the fuses.

The fuses are there to protect the car. If you put too much current through a wire, the wire will overheat and eventually can start a fire in the insulation around the wire or in the carpeting or anything else in the car that is flammable. The point of the fuse is that it will melt and "blow" before the wire and/or the electrical equipment will and will prevent any more electrical current from flowing through the wire and the equipment.

If you're asking this question because you're having a problem with your fuses blowing, you're going at it from the wrong direction. There is an electrical problem somewhere that needs to be fixed, and using larger fuses is not the way to fix it. You probably have too many accessories (neon lights, game consoles, LCD screens, etc) on one circuit which is causing that one circuit to have too many amperes of current to flow through the wire & fuse.

Peace,

I had a problem in my old car with my hardwired radar detector. I was dumb, and didn't put a fuse on it, and when it shorted out, I had a nice fire going through my dash and headliner. Trust Keane on this, you don't want to go with a higher rated fuse on anything in the car, if you have a problem, the current might not get cut off. Do the investigation on this, and figure out what the problem actually is, you'll be safer in the long run...

I don't have problems with any fuses really. I have had a few dealing with only 3 so far because of the way I hooked my sidemarkers up. I was asking about setting all the fuses the same because I'm just going to buy bulk 30 amp fuses to keep replacing the ones my amp blows on me. I don't know why it does it but it only does it on occasion. I'm thinking there's something I'm not seeing in the wiring.

Can you reproduce the problem? If so, and you'll go through a bunch, start reproducing it and taking components out of the system, eventually, you'll get down to what's causing the problem. It may appear to be an amp out front, but may come down to bad wiring, or insulation that's worn off a wire. I know it sucks, and is a pain to spend that much time, but you should really figure out the problem, before it get's bigger. Let me know if you have any ?'s that I can help with...

[Merc123]

Nope. I can't reproduce it. I think it might have something with toggling the switch too much or flipping it on or off too fast/too much at one time.

[RhythmsDJs]

hmmmm, kinda strange. I would say the first thing is to be able to reproduce it. Once you can do that, then getting down to the root of the problem is a lot easier.

yeap
