Hi. I wonder if you can help me. I have a Landlex Broadway S400x RS scooter (2008) with a weird problem. When moving off the power suddenly goes completely – no lights, no status LED, nothing. If I leave it for a while, the power returns until I try to move off again. The batteries are fully charged. I’ve fitted new motor brushes, checked all visible wiring and plugs, including dismantling the 2 battery boxes to check internal wires.The cut-out on the battery box stays on (i.e. doesn’t trip) and all ancillaries work OK until I move off. Is there a safety breaker somewhere that could be causing this? I’ve contacted the manufacturer in Taiwan, but they have not replied. Any ideas? Thank you in advance for any help you can provide. (P.S. do you know where I may be able to get a wiring diagram?
