Yes, I am not surprised. I started with a 2009 Kymco Agility 50 and it had a run-stop switch on the right handlebar. A bright red one. Same side as the starter button. I can see all kinds of situations where this may be missing. But if it is missing there should be, or could be a substitute start button. So what I am saying is I have a lot of questions to ask just to try to understand what your situation is, the "tester" you are using and how you are using it. So if you can be a little more detailed in your descriptions maybe someone could help you find the problem.
