For the time being, I got it working, but I'm going to call the service adviser and let them make the call. I took the car on a drive to giggle some of the air pockets free and it worked. On my return home, the coolant level was down, but it was definitely flowing. Two of the charger temperatures remained below 100 F, but one crept up slowly. Forscan calls it 'C'. I think the first 2 were more critical. Current sustained 28A until charger temp 'C' got to 150, then it dropped to 19A. As charging progressed, the flow of coolant through the batteries seemed to have fewer and fewer air bubbles.
Yeah, it would be nice if I could get all the pumps going to purge the air bubbles, but I don't think Forscan lets you do anything other than clear codes...but I'm new to it.
