Doug S -

I'm curious...  How has your experience been since your posting on this?

I have a 2013 DS 11KW, and it has failed many times (3 or 4 BMS's, a welded contactor, failed current sensor, failed capacitor, intermittent startup failures, spurious shutdowns while at speed).  According to my dealer (Harlan), this bike has been a very abnormal case.  I also had to invest in AAA Plus RV, and have used it 3 or 4 times.  It has been in the shop for almost the last 5 months now...  In October 2015 it started failing while at highway speeds (which is a HUGE safety issue) and I almost got hit by an 18 wheeler.  So, I pretty much gave up riding it.

To Zero's credit, they ARE trying to resolve it...  Albeit, 5+ months is probably unreasonable even for a boutique motorcycle.

In general, I'm just asking for a status update I suppose.  Did they take care of you, and has your bike let you down since?

Thanks.

Zero Motorcycles Forum | 2013+ / Re: Charging intermittently stops with 2013 11.4 DS / Contactor Issues too
« on: October 04, 2013, 02:04:00 AM »
I figured I'd join and comment as I am a recent owner of a 2013 11.4 DS.  I too had experienced a few "charing dropouts" since August 2013 when I bought the bike.  I've put about I would go out to start my commute and discover something went wrong during the charge cycle.

I went up to my dealer (Hollywood Electrics) yesterday, and they hooked me up with a new firmware revision (62 I think I heard) that is supposed to resolve this issue.  After two trips (1 near full discharge), it did successfully charge up fully over the course of the night.  I was going to wait a couple weeks before calling it fully resolved because the "charge dropout" only happened maybe 5% of the time.

This morning I happily found the bike fully charged, but it unfortunately faulted on power-up with a "4 blink, 1 blink" warning code.  This code seems to indicate a welded contactor (contact closure without an energized coil), which is a safety check.  The bike won't allow driving if this condition occurs - for obvious reasons.  After speaking with a rep (Chris) and getting some good technical info, Zero and Hollywood Electrics are taking care of it under warranty.  I might try to bump the contactor to attempt to free it up.  Due to the fact that the firmware was updated the previous day I am not entirely convinced it is not being caused by the firmware update itself.  The Zero rep informed me that there is some precharging functions built into the firmware to minimize arcing on contact closure, and that they have been pursuing similar issues as mine.  They did hint that similar protections may need to be implemented on contact opening as well.  I expect it will be resolved soon, as both Zero and HE have taken good care of me so far.
