Does your charger work if plugged into a different circuit? Does anything else work in those circuits, such as a light or electric fan, or?
In my experience I have blown two onboard chargers on 2015 SR in 4 weeks. The first quit the first night home and the second 27 cycles later. This bike was a demonstrator with 230 miles at purchase. The APP logged 25 cycles. I haven't figured out yet if a 'cycle' is recorded when it reaches 100% or just any time it's plugged in. The first 25 covered 230 miles, the next 27 cycles covered 1,200 miles. The 2nd charger burned out after about 10 minutes of charging following a 30 mile ride. No problems in the house service box as the outlet was still live. Fortunately I have a dealer 15 miles away.
I don't wish to offer opinions, complaints or suggestions this early in the game other than of course it is "disappointing."
As most of you know, Zero advertises heavily on social media. The comments following one of their posts are often amusing, usually ignorant, but occasionally right on. One owner's advice was, "don't buy one of these unless you have local service...they are great when they work but could be a nightmare if you can't get authorized support locally." I think this applies to any expensive and complex product, but especially one like a Zero Electric since no one outside the 'network' really knows how they work or how to fix them.
