My daughter has a TW200 and she is complaining that the headlight is dim and the blinkers are slow to start the first blink cycle (e.g. you turn on the blinker and then have to wait for awhile before it starts blinking.) The bike seems to turn over OK with the starter so my assumption is that the battery is OK. Where would I start checking? Regulator? Stator? Something else? Is there a good way to check if the various parts are ok?
