    So after i went for a short ride, my electrical system just failed, nothing worked, so i changed the fuses 20Ampers were on it, so i replaced them with 20Ampers aswell. And now everything seems to be working other than the brake light and the indicators

        Sounds like the indicator relay has failed.

        You're not running any LED lights are you?

          @calum nope, but which relay is which? And that doesn't really explain what happened to the brake light?

            @bananper 20 amps will blow the bulb mate.

                @bananper You said you replaced it right? So it probably failed as it took out a bulb when it went open circuit.

                It's merely a suggestion, go and have a look.

                  @Calum What's the right amperage then?

                    @bananper What you talking about?

                    I've said something probably went open circuit, hence why the fuse blown. It most likely blew the bulb at the same time. Fuses are exactly the best way to protect circuitary.

                    I'm waiting on you to go and actually have a look to see if the fuse is blown.

                    I think 20 amps is correct. It might have been 15 come to think of it.

                      @calum so one of the fuses seems to be blown

                        @calum i've looked into the haynes manual and it says that the TZR model has 20A fuses and the DT model has 15A fuses, can this be the cause?

                          @bananper What? Do you have a TZR?

                          If the DT is 15 Amps, and you have a DT, then I'd strongly suggest putting in a 15 amp fuse.

                          As I've said already, sounds like you have a dead short that you need to fix.

                            @calum well now i took out the brake bulb, one string is working the other is not. And i think the turn signal relay is blown aswell

                              @bananper Cool, but as I say, there'll be an underlying issue you need to figure out else you'll just end up damaging components. Even the CDI.

                              Based off you're fuzzy description, I'd suspect that a relay has gone open circuit, or more likely the rectifier has packed up.

                                    @calum the indicator should make a clicking sound when turned on shouldn't it?

                                          @calum https://youtu.be/qK4GSDT89mM soo heres what's happening with the indicators. I put a wire on instead of the relay so it would keep lighting. It worked perfectly fine on the right side but on the left it didn't work, any ideas?
