Fishfiles 20,147 Posted July 4, 2022 Hi Rene , if I am think the same fuse , it is a 30 amp in a seperate fuse holder other than in the fuse box , if so it goes to the ignition switch and the voltage regulator , voltage regulator , might be your problem , I have seen the wiring harness get messed up on the 450 right in front of the air box where the harness goes from on side the frame to the bottom of the frame Share this post Link to post Share on other sites
Derf40 140 Posted July 4, 2022 Hi Rene, a word to the wise, find what is the problem before you replace the fuse...30 amps is more than most of the wires will handle, most of the wiring harness will not handle 30 amps. check your wiring diagrams for the 30 amp circuit. ...derf. do not keep replacing the fuse. investigate the problem first.. good luck Share this post Link to post Share on other sites

Fishfiles 20,147 Posted July 4, 2022 Fuses are too expensive to burn up searching for shorts , use a multimeter , pull the blow fuse , stick the two probes , one in each side of the fuse blade holder of the blown fuse , start unplugging connectors till the meter goes zero and that is the circuit with the short Share this post Link to post Share on other sites
