Last fall I bought a 2011 Zero XU for cheap because it didn't run. There was a bunch of wonky stuff happening; random beeps, lights flickering, wouldn't charge, etc... I tried a few things but ultimately gutted everything on the 48VDC side of the equation along with the controls system. I attributed the weirdness to the MBB being a glitchy piece of shit and since the BMS was so integrated that went too. So, I converted it to a conventional E-motorcycle conversion with an Alltrax SR48300 controller and a GPS speedometer. The only thing I don't have now is a "gas gauge", but a voltmeter on the dash will remedy that as long as I know 42VDC is "empty". The key powers the solenoid and turns on the DC converter. Everything on the 12VDC side is the same, fed from a Sevcon DC-DC converter. I'd put up pics but it looks exactly like any other Zero XU.
