Yes, as my crossed post indicated.
The Mitsubishi people found that a brand new OBC cost of the order of US$4000, and that's for a 3.6 kW model. They found it far better value to find a wrecked OBC and install that. With the iMiEV, there is no VIN locking of the OBC; that may not be the case for Leafs.I'm guessing it's pretty likely that I'll be buying a new onboard charger.
There is a common fault with the Mitsubishi version of this charrger, where two small capacitors tend to blow up (literally shatter into pieces). If you do use an OBC from a wreck, it may be worth replacing the equivalent of those capacitors before installing. Use higher rated (e.g. 4 kV) parts. Mitsubishi USA actually extended the warranty on the OBC to something like 10 years, so several of them have been replaced under warranty. It may not be wise waiting for Nissan USA to follow suit
