I recently bought a new controller for my dead bike and also got a "tester". I have not been able to get a 5volt throttle reading from the new controller and I have questions able using the tester and hooking up the controller and the wiring. If I don't get the exact wiring hookup right can that prohibit my getting the 5volt LED for the throttle?? I've tried 2 different throttles and get no indication of current coming from the controller. Is there a way to test this with a meter? A patient soul familiar with this would really be appreciated !!
