The first 2 charging lights blink slowly off and on, but no charging happening. The timer is set and it should have been automatically charging, but it was not. Had to delete the auto charge and tell it to CHARGE NOW. System has been working well for the last 3 days behaving itself. Does it mean that it had not got to when it needed to charge for departure? Or could it mean I interrupted something, by opening a door to add items to the vehicle?/ Anyone else had this happen Thanks.
