Fusible link upgrade possible?

All I can say is WOW.... people really like to over think and over complicate things....

If you solder in fusible links on the correct circuits (alt charge wire, and main feed into vehicle) it will be fine. There is no need for overkill with marine grade this and super duty fuse that.....

I have professionally wired cars from scratch for years and NEVER used most of the things suggested.
First and foremost.... UNDERSTAND what your doing before you start. If you dont, TAKE IT TO SOMEONE WHO DOES.
