Can I replace a 15 amp fuse with a 20 amp fuse?
The answer: It’s possible, but not advisable without an electrician evaluating the situation. You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire.
Does it matter what fuse you use?
It doesn’t matter which end of the fuse holder gets used for going to the battery and which goes to the jack. Fuses don’t require current to flow through them in a certain direction so either way is fine. But typically line is the side that the power comes in on and load is the power going out.
What do a bad fuse look like?

A reading of OL (Over Limit) definitely means a blown fuse. If the fuse is blown, replace the fuse with one that is exactly the same (see panel).
Does fuse color matter?
As long as all the other specifications match (specifically amperage, voltage and receptacle size), the color will not make a difference.
