If he's burping or something else I might agree. The only issue he might have is heat. Make certain that the fuse isn't getting too hot or over heating. If the wire insulation looks like it's "melting" or "burning" on the edges then you need to upgrade your wiring.

Honestly I really don't know where to start with your install so I didn't want to answer. I think you need to start reading and educating yourself on a lot of different things. Pick one topic and we'll start there.
