You will need a 12 volt test light to do some electrical circuit tests. If you do not have one you can get a cheap one at any auto parts store.
Begin by clamping the end of the test light to the negative battery post. Hold the tip of the light to the positive battery post, the light will come on. Switch the ignition switch on. Does the test light stay on? Do any other circuits on the bike work: horn, lights?
