I also reset the IMA light just by pulling the fuse. I have the Torque app on my phone and a Bluetooth OBDII adapter so I reset the check engine code as well after the IMA. I fully expected them to come back and in about 10 miles or so they did. I did the jumper on the OBDII and read secondary code. Only one a 78.
So I guess the next thing is to try to sift through all of the grid charger possibilities and decide if I can put one together and how much I want to spend. Do these ever come for sale in the Forum?
