thanks for all the info, guys! I think I understand the issue and consequences now. say that a 30-amp fuse was placed in a slot requiring a 20-amp fuse. and say that fuse blew. what is the possibility that it could fry wires/electric components and/or cause a fire because too much current passed through before the fuse could break in time? are these "risks" a high possibility and one or both scenarios are likely to result. or when you guys talk about the possibility of fires and damaged components, you guys mean that's what could happen but not very often except under extreme conditions. thanks again.
