Gs450 keeps blowing fuses

[724x4a/cchevy]

My 82 450 keeps blowing fuses. I have replaced the voltage regulator and im not sure if its a short or what. I figured i would ask you guys before i took the wiring harness off and inspected it. Did i hear someone say these bikes had altenator problems like overcharging? Also, what fuse should my 450 have? It had a 5 amp fuse in it when it blew. The bike will start and run, but it blows the fuse every time. Thanks for the help (im a noobie)

We need more details. First you need to explain exactly what fuse is blowing, and exactly when that fuse blows, ie: as soon as you turn on the ignition, as soon as you start the engine, as soon as you flip on the directionals and so on....

Fuse

I have a 1982 GS450TXZ, the owner's manual specifies a 15 amp fuse. Hopefully that will not blow like the 5 amp fuses. Last year my R/R failed, burned out all lights that were on at the time, most likely caused some damage to the coils, but the main (only) fuse did not burn out! I don't understand. Best wishes, DickV

You've definitely got more than 5 amps flowing through there - explaining the burning fuses now.
But, the original fuse (assuming it was 15 amps) burnt for a reason.
Sometimes it's just an old rotted fuse, but it's more likely a failing R/R or a short.

Are the fuses melting or burning out? My 550 needed the contacts on the fuse block cleaned...they were heating up the fuse and melting the ends of it.
