    gs1100g keeps blowing main fuse

    I have a GS1100 G 83 model . the bike was running fine but now she keeps blowing main fuse . She'll sit and idle all day till I go to rev her and that's when she blows the fuse. Any iders on what could be causing this to happen.. The only thing i'v changed on her is LED indicators and flasher unit
    cheers

    The guy who owned my bike before the guy I got it from told me that every couple times of revving it all the way out, the main fuse would blow. I hit all the big contacts and connectors (and the back of the fuseblock) with Naval Jelly and then rinsed it clean and have not had it happen to me at all. Maybe it's a corrosion issue somewhere between the main and the coils?

      yeap have done most of that but didn't think of the coil's. I'll go have a look

          A bad regulator/rectifier. (R/R)

            Yes just got on to that . Started the bike after disconnecting it and main fuse didn't blow
            Cheers guys thanks for the help

                a shorted stator will pop the main fuse.

                    Not certain what you are saying.

                    It is possible that your R/R (and stator) does function but at sometime, like under higher voltage (or current or temperature) the R/R (or stator) has something that just for a brief time shorts to ground and that would blow main fuse.

                    If disconnect the R/R from the bike harness, that will remove the R/R (and stator) entirely from the bikes wiring. The bike will start and run without the R/R connected (just will not be charging the battery).

                      When I rev the bike to 1500 she blows the main fuse but when I disconnect the R/R she doesn't. but with the R/R connected it's pumping around 13 to 14 amps or volts to the battery

                        Substitute a different R/R.

                          Dump the Suzuki R/R and install a Honda unit. You will have to solder connectors, but once installed on the bike you can forget about R/R problems.

                            Because the stator puts out power and the R/R requlates it, does not mean that the stator or R/R cant have a problem where it blows fuse at high rpm (higher voltage, higher current).

                            I suspect the R/R.

                            Or is a slight chance it might be with higher RPM is more vibration and that is causing some bare wire to touch ground somewhere. Maybe could test that just by wiggling wiring harness and see if it blows fuse right when wiggle something.

                              What size Honda unit would you recommend ???
