We have two Volts, a 2012 and a 2013. Yesterday I found that the 2012 did not charge overnight on the supplied level one charger. This is the charger with the charge level selection switch on the case. It also has a heavy orange cord. After a bit of checking on the charger, I noticed that the lights all came on and turned green. However, when I plugged it into the car, nothing happened. The dash light did not come on, nor did the horn sound. It had worked flawlessly earlier in the day. As we have two cars, two cords, and plug them in in two locations, I checked all of the possible combinations. In all cases, this cord did not work (although all of the lights were on) and the other one did. Any suggestions? I have read about fuses burning out in level two chargers. Do the level one chargers have these fuses? Thanks
