    @atraiss You haven't blown any of the fuses that sit alongside the battery have you?

      @atraiss bike runs good, without any problem.... just that servo motor.... before rectifier get faulty, everything worked perfectly..... didnt notice that rectifier is burnt ..... put another servo motor also worked for 10 min, then burnt out. then noticed that theres too much voltage going out from generator, got the rectifier, got new servo...not working, changed the cdi, ignition, still no working

        @atraiss Ah okay, yeah I see.

        Well there really isn't much in the way of this.

        You can run the engine without the output of the Stator, just the pickup is required. But it could have damaged the CDI if that's the case.

        The servo will respond to the "pickup" sensor. Are you sure that this is in working order/

              @atraiss What do you need me to be more specific on?

              The "stator" plate is the coil of windings that the magneto spins around that generators an Alternating Current (AC). This is not stable and therefore is rectified. The motorcycle doesn't need the generator/stator to operate, it just won't be able to replenish lost electrical charge.

              So to ensure it's not the stator causing interference, you could delete the stator from your setup.

              But I also wonder whether the coil pickups have not been damaged.

                If the CDI & servo motor are good it has to be your wiring loom, or other component...
                There is no magic sentence that anyone can write that will fix it. You’ll have to check voltage and continuance on the working bike (with and without your servo & CDI) and check your loom against it. See what wires are giving different readings...

                Hope this helps...

                  @atraiss I suspect there's a wire somewhere that burnt up sad thing is it can be anywhere in the loom wrap atleast thats what I would suspect

                      @atraiss Great stuff bud. As I said, not having a battery connected can cause issues.

                        @calum but there contact, and power was going though, because the servo did the cleaning cycle when ignition is turned on.... But seems no enough to work fully

                          @atraiss Yeah, a dodgey connection though? When you're going over bumps and stuff. Doesn't sound ideal.
