I mean EVERYTYHING other than the charger. There are contactors on both sides of the pack, so the controller and motor are fully disconnected. I also disconnected the volt/amp meter, and BMS (12v power) as well. Also disconnected the "battery +" wire to the zilla hairball. Unhooked the DC-DC.
I'm wondering if I'm getting dirt/damp leakage from the pack to the frame. On Wed Jun 01 18:08:15 PDT 2016 ev@lists.evdl.org said: >Could you be a little more detailed?
