I'm not sure about your bike buy my G5 has three black plastic fuse cases with the wires running into the top and bottom of each.
Inside each case the fuse that is held in the clips with the wires attached is easy to see.
Along with each connected fuse, each of the cases has a spare fuse which is easily removed and installed into the metal connectors with the wires attached.
As for blowing a fuse, everyone, including me will say you need to check all of the wiring for a short to ground. These Indian made wiring harnesses are not the greatest and the use of black plastic tape for protection against abrasion is a poor idea.
Anyway, about a year ago the main power fuse in the first black plastic case blew.
I replaced it with a American made fuse and the bike hasn't had a problem.
I looked for a possible short and never found one so I'm assuming some of these Indian made fuses can blow even when everything is fine.
