This afternoon I tried starting up the bike, finding the warning led blinking irradically and the bike not arming. After about 10 seconds, all digits on the cockpit started blinking. I keyed the bike off, waited a few moments, and then after keying on the bike armed in 4 seconds giving no errors.
So at work I dumped the logfiles, and threw them through the logfile parser to find the following part:
09244 11/21/2016 17:26:43 b'Entering Charge Standby Mode'

This goes on for about 50 lines, and was last night right after the bike stopped charging.
The weird part for me is the fact that 'Charger 5', which looks like the charge tank, keeps connecting for 6 seconds, then disconnects for a second, then connects again etc.
The log of me keying the bike on however shows:
09350 11/22/2016 03:48:32 Sevcon Turned On
09351 11/22/2016 03:48:32 Sevcon CAN Link Down
09352 11/22/2016 03:48:33 Sevcon CAN Link Up
09353 11/22/2016 03:48:33 b'Precharge Lost. CapV: 85V'
09354 11/22/2016 03:48:33 Module 00 Opening Contactor vmod: 116.047V, batt curr: 2A
09355 11/22/2016 03:48:33 Module 01 Opening Contactor vmod: 0.000V, batt curr: 0A
09356 11/22/2016 03:48:33 Sevcon Turned Off
09357 11/22/2016 03:48:35 Sevcon Turned On'
And this repeats about 12 times, before I key off the bike and try again, after which no more errors occur...
It looks like the Sevcon was in sort of a loop, becoming available but then turning itself off again, and on, and off...
Is this something I should worry about?
[edit] It's a DSR 2016 with dealer-fitted charge tank
