Traxter over ride mode to start

Have 2001 Traxter 7465 that the over ride mode to start by pulling in on brake lever to start while in gear stopped working. It will start if put it in neutral or park. I see where others have had the rear brake switch go bad, replaced with NAPA Echlin SL 134. My traxter does not have that switch. Any ideas what is causing my over ride mode not work
