Fuse probs
« on: November 07, 2012, 07:37:15 pm »
So, the other day, I went to turn on the lights and go a cloud of smoke from the floorboar d, went to take a look and the tail-light fuse had melted, every single fuse I put in there now, blows instantly when I turn the lights on. The one that melted, I found out it is one of those uber cheap ones, without the white lettering on the top. Anyone have any suggestio ns? I have but bigger amp ones in, checked for loosewire s, cd player is wired good. Its a '90 crx HX.

You have a short somewhere in the circuit that is causing the fuses to blow. I'm going to speculate it has nothing to do with the "cheap" fuse you originall y had in place. If you've done any work or anything that would require pushing around wires, look in those areas for a cause of the short. Otherwise it could be a case of a wire rubbing and finally wearing through the insulatio n, a bad switch, etc.

Until you fix the short, any fuse you put in place will likely blow.

Alright, well I traced all the wires from the fuse box to the tails, no loose wires or anything grounding it out, I did however, buy a set of different fuses from the store, stuck a 25 in it and it works perfect now, Im not sure how long it will last, but I have had it in all day with no problems, I know you arent "supposed" to put bigger amp fuses in it, but it imediatll y fries all 10A's i put in there, so it might be the actual fuse box itself. this all happened right after I put in this "cheap" fuse that melted, so it leads me to believe its something with the fuses.

So you've got a circuit designed to support 10 amps through which you are running somewhere between 10-25 amps?

That is correct, any ideas on what could cause this?
