The chaffing would make sense... I was doing some testing and noticed that the OAR reset and the P0020 code happened at the same time... when I moved the gear selector from D to R... the gear change made the car jump a little (I am on a hill) and that's when everything happened...
I don't have a fuse 67 in the fuse box next to the battery...
I am also getting acid build up on the positive terminal on my new battery... this is screaming like I have short happening somewhere...
