On my 1999 Toyota Corolla, one of the wires coming out of the left side fuse is completely torn. See images. It goes from the fuse to the alternator. Not sure how it has happened. There is no burn smell or anything.
a) Do we know what is its significance or what is its used for? Sometimes my car would just keep clicking and wont start despite having new spark plugs and new battery.
b) How do I replace this wire?
c) Is there a ready kit available in the auto stores or I need to put any wire?
d) What wire guage should I be using?
