What happens if you blew a fuse in the fuse box, and replaced it with a higher amp fuse?

Would it harm anything?

Just asking, because I went to the Dealer to pick up a few fuses (10a), and they were closed.

yes, it could harm anything... if you run a higher amp fuse, you run the risk of burning your wires, especially if whatever caused the fuse to blow in the first place is still there.

its usually recommended to replace with the same amperage fuse, or LOWER amperage. never replace it with a higher amperage fuse unless you absolutely have to.

You will run the risk of melting the wires in the harness!!! Locate an unused fuse that matches and use it.

there should be extra spare fuses in your fuse box check there fist before using a high wattage fuse

+ Juan. The fuse acts as your weak spot, it was engineered that way as far as load, #/guage of wire, distance, etc. Upping the amps on a circuit designed for less is not a good idea.

You will only cause harm if the current thats passing through the previous 10A fuse is greater then 10A, which most likely won't happen if this is just a temporary fix, however you do run that risk.

Well, I appreciate ALL of the info from everyone.

I tried to locate another 10a that wasnt in use, and there are none. I already used my extra 10a fuse that the car came with last time I blew the same fuse.....I'm a dumbass, I know....the problem that caused this as well as last time is that the positive and negative wires I was working with rubbed together and created a spark which blew the fuse.

Nothing major. It just sucks because I have to wait until Monday for the fuse to finish my project.

The damn auto stores here dont have the new fuses yet that we all use, just the old school ones.

Thanks again to everyone for the info.......based on everyone's similar answers, I think I will just wait til' Monday.

I'm curious which fuse did you blow?

ebumdude · 03-16-2008, 02:11 PM

The 10a fuse that is tied into the dome light, map lights, and clock.....2nd time blowing it, but it was my fault though. (both times)

I was just asking about the spare higher amp fuses because I am anxious and didn't have the patience to wait until Monday for the dealership to open.

MrSo0h0o · 03-16-2008, 02:15 PM

what are these new fuses u are talking about? do u have an example of what they look like? im curious lol

ebumdude · 03-16-2008, 05:09 PM

Our fuses that we use in the Camry's (gen6) are smaller than the ones you can just buy at any auto store......at least in Hawaii anyway.

To me, that makes them "newer".

***RningOnFumes*** · 03-16-2008, 05:25 PM

You're talking about the "mini" fuses? (mini in size, not rating)

ebumdude · 03-16-2008, 06:33 PM

exactomundo....."mini" ones.

white07cam · 03-16-2008, 08:51 PM

ehh, just use a penny instead of a fuse...

JUST KIDDING
