right one thing at a time,the starter relay is just in front of the battery to the right slighlty ,the battery sits between your feet as you sit on the bike and there is a small cover held on by a torx screw.the starter circuit must be completed to make the starter motor turn to do this the ignition must be on and the battery charged and a good fuse fitted(not blown)then one of the two brakes needs to be pulled in and the start button pressed.to check the brake light switches work just look at the tail light and see if it lights up when a brake is pulled.if not then check the bulb first and if still no luck then the switche/s the switches bridge the circuit when the brake is pulled so to test the circuit if both switches are faulty which is common just get a small split pin and part the ends and push them into the small spade connectors that fit onto the switches and see if the rear light illuminates.if so then press the start button if your hear a click (that will be the starter relay)and the starter motor doesnt turn then either the wire is corroded where it screws to the small spade terminal on the starter motor or the starter motor is faulty.ok good luck let me know what happens and ill lead you the right way ps its a very common thing for the starters to give up on these bikes same as many other 50cc auto's
