Default general car electrical system question

what would happen if you put a higher amp rating fuse in a slot that didnt require it.

example: 10a in a 7.5a slot

it will allow 10amps through voiding the point of having a fuse there?

If the system was overloaded you would risk damaging whatever component the fuse is going to. I can't really think of any way the electrical system would get overloaded besides a busted voltage regulator on the alternator, which happened to me once. My battery was pushing 20V at 2000RPM :rofl: I was so afraid my airbags were going to explode or I was going to fry my ECU when I drove to autozone to get a new alt h:

But seriously, don't even bother. Just wedge a bullet in there.

if the fuse blew... chances are some component is fuxxored. putting in a higher fuse risks damaging that component even more, as well as burning out wires that are not gauged to handle higher current.

reason i ask is i just recently noticed the backup fuse in my underhood box had a 10a instead of the 7.5a that was supposed to be there. i quickly replaced it with the right amp. this is the first time i noticed it after constantly going in and out of it trying to fix another problem.

Current = Voltage [applied] / Resistance

You truly are stupid if you can't understand that equation that I put in ENGLISH WORDS and not scientific symbols.
