The little digital unit is playing up on my e-bike. It's a basic/early model that just says King-Meter in bottom right and J-LCD in top left. The bike just wouldn't turn on at all after a long layoff. Now it's not the battery because I have another bike that shares the same HL-battery and I just swap it over when I need, as I can only ride one bike 
(too tight to buy another basically)
When I sit the battery on the "dead" bike, but plug the meter in on the other bike it switches on no problem. So the circuit in general is fine. I had a fiddle about with the faulty unit and I got it to switch on. Happy days! Or so I thought.
Rode it up down the street no problem. Throttle worked fine and the power modes switched up/down no problem. But when I came to switch the unit off it wouldn't do so. No combo of buttons would switch it off. I had to disconnect the battery to shut it down, and then when I put the battery back on it wouldn't fire up again. Back to square one.
Is this just a duff unit or duff switch? The switch is separated from the head unit and linked by a cable. It's not "all in one" like the King-Maker KM529 on the other bike.
Any thoughts?
