I don't think so. That he gets a difference with the fuse pulled indicates that the fuse is not blown.
And replacing a blown fuse, if that were the case, will 95% solve nothing. Fuse is symptomatic of a problem, not the problem typically.
Have to find out what blew or fatigued the fuse for the cure. Sounds like OP has a problem with one of the devices that the fuse feeds.
