Lou 12 v trickle charge to the motorcycle battery is the trick.Update: The pending update for 22-PU1009-MIL-DTE should have been installed automatically last night at 9:00 PM in accordance with the previously established schedule I set up. It failed. Today, I have tried twice to install the update manually, but both attempts were unsuccessful. They stopped in-process for some unknown reason. Tonight, I will charge the truck up to the 80% level automatically. At 7:00 AM tomorrow morning, I have scheduled the update to be installed automatically. I wish I could be a little more optimistic. PS -- Just for grins, I checked the frunk battery. It was reading 12.55 volts, which I assume should be sufficient to do just about anything. Keeping my fingers crossed.
