A starter solenoid with an inline high-current fuse? Excuse me? The solenoid COIL (the solenoid part of it) is fused, but not the CONTACTOR part of it which shunts battery current directly to the starter. The starter is current-limited by the back-emf of its rotor windings. (Look up the words you have not learned yet.) As long as the solenoid is actuating it is fine, dude. Check yer grounds and the starter itself. Heard of resistance and continuity? Carbon brushes? Getcha one of them motorcycle maintenance and repair books fur 20 bucks on Amazon an reedya sum. Back to basics, dude.
As long as you don't blow the fuse, all is good. Check the voltage between the solenoid and starter when you are trying to crank it. If that is less than about 10V, check the voltage going to the solenoid and at the battery when you are trying to crank it. If the battery voltage drops below about 10V, the starter is probably bad if you are sure that the battery is good. If the battery voltage is good and the voltage going to the solenoid is under 10V, the wire from the battery to solenoid is bad. If the voltage between the solenoid is below about 10V, the solenoid or starter is bad.
Check the size of the Main Fuse, if a 40 or 50 you should be running a larger sized.
What clicks? You sure the starter jack shaft is throwing out. It could be starter clutch. Make a vid of what's happening and repost. Pull the starter out and do a bench test. Know how to do that? You tube it.
