Hi new Karma owner. Used my 110v charger for 2 weeks every night. I went away on a business trip for 10 days. The Karma was plugged in. When I returned I noticed the red light flashing on the charger and 2 green bars flashing. The car was fully charged. However since then it will not charge. I presume a new charger will resolve my issue. Question; will a Chevy Volt chargers suffice? Thank you all inadvance.
