Fuse or even wiring burns through

Should your problem relate to a AC System from us, than please read here

Fuse burning means you have more current flowing than should be. In other words there is somewhere a shortcircuit (or partial shortcircuit) outside the regulator in the motorcycle grid.

Here only systematic searching will find the problem.

First disconnect the battery, take out all light bulbs, disconnect the horn (important, that is a prime suspect!).

Than reconnect the battery. Should the fuse now stay, reconnect the horn (test the horn!), than one after one reinstall the light bulbs back and keep checking.

If at one point your fuse burns again, the last reconnected part or the wire to it is the culprit.
