I had suspected the wiring into the box, so it's good to know u solved your problem by swapping them out. Will try sort it over next few days and post up what the fix was. Thanks guys!

Yeah it was. Both batteries were charged, and when put into the bad bike, they both lit up as normal on the actual battery, but the unit on handlebars failed to light up.

Hi guys, Just joined the forum, looks like a great source of help and advice. I'm hoping someone can help me with my power problem in the mean time.. Basically, my battery is fully charged, and of course I turn the key and press the button on top of the battery and I get full green lights, but when I press the power button on the handlebar unit, no lights flash up. I do see a very brief very feint red light flicker on once when I press the power button, but that's it. Has anyone got any suggestions? Could it be fuses in the battery itself? A corroded wire on the unit on the handlebars? Or something else? Finally, I've got 2 of these bikes, and I swapped the batteries around to check and the battery worked fine on the other bike, so it seems to be a wire/connection/unit on handlebar issue I'd think. Many thanks in advance. Steve.
