In the previous cases of this fault that we are aware of, the solution was always to replace the entire on-board charger. However, when we were asked to diagnose and repair a 2011 Nissan Leaf that had a charging fault we decided to take a look at what was actually failing in these chargers. As it turned out, it was able to be fixed for less than a dollar worth of parts. The charger still needed to be completely removed from the vehicle for the repair, but that would needed to be done for a charger replacement anyway. We hope that this video helps other people from around the world with the same problem. PLEASE NOTE: The high voltage system on electric vehicles needs to be treated with extreme caution - we recommend this repair is only undertaken by people with the knowledge and experience to work on these vehicles safely.
