One brake is illegal on bikes/trikes for road use so good job it will be remedied.

You had the answer early on in the thread, the controller has a large capacitor on the inlet side which will hold a charge for some time, turning the lights on will momentarily drain the charge and then not again until the battery power is connected again.

Theoretically yes, the yamaha motor had to be replaced due to bearing play. Also GH had to carry out a fairly simple but silly battery charge /discharge port repair to save a whopping £800 replacement battery bill as the dealer washed there hands of it because like bosh, yamaha have in effect a...
