Test Battery --> Test Rectifier -->Test Stator In that order.
MAKE SURE your cables going to your starter are not damaged. It could be shorting to ground and draining your battery when you try to start the bike. Ask me how I know
Also I would unplug and plug in your rectifier connector because sometimes they can not make proper connection and need cleaned. Check the rectifier and wires coming from the stator for any cuts or damages. They wires may be shorting to the chassis. Make sure the leads are clean and maybe add some conductive gel or whatever that stuff is called (Cant think of it
) to the plug.
