I have a 42 wlc 45 ci and there is an inline fuse from the battery to the circuit breaker and it has recently started blowing them after a short ride.The original fuse was a 20 amp 32 volt and I replaced it with the same. Why are they blowing after so many reliable years of service?

SOURCE: car amp blows 12 volt wire fuse

the wire from your battery is blowing fuses? and you are using 20-30 A fuses? mine has a 100A fuse..look into getting new wire plus my wire is 4 gauge.., 1600 watts is too powerful for a 12 g wire and a 30 A fuse

SOURCE: 30 amp main fuse blows when the key is turned on.

SOURCE: Wiper fuse keeps blowing intermittently.

It looks like the wire circuit for the wiper motor is touching the car body when shaken so the only thing you can do is shake the wires and terminals yourself while engine is running then maybe you can pinpoint where the earthing is.

SOURCE: blowing fuses,battery too hot

Sounds like the voltage regulator is not working properly.

i would be looking at the voltage regulator,if the regulator is faulty the alternator will not be replacing the voltage that the bike needs to keep running
