After some 2 months I finally got my Zero synchronized with my smart phone via Bluetooth. It took over an hour. Probably my fault for using an old refurbished Tracfone that I am not very good with.
Near the end of the synchronization process the SOC indication dropped from 65% to 0% and all four blinkers started flashing and the 12 volt battery warning symbol came on. I also had a message and fault code saying low battery voltage. I then plugged in the charger cable, but the flashing blinkers continued until I cycled the ignition key. At this time the SOC came back up and read 63%, I think. After a short while the "red" battery warning light turned off and only had a "red" error code icon which I cleared.
Manual is not very clear to me on the behavior of the 12 volt battery, can anyone enlighten me? I did not read anywhere that you should have the charger cable plugged in when programming, or was I just too slow? Is there a way to monitor the 12 volt battery voltage? All it says is do not let it drop below 10 volts I think, how?
It looks like my phone app got properly mated to the bike, test ride tomorrow ti see if it works unless it is raining again.
