"I WOULD STRONGLY suggest you do the James1549 ground cable mod, and make sure all battery connections are clean and tight. I"ve done the mod to my last two Roadsters and we do it at tech days quite often.

Thanks for your feedback.
I installed a trickle charger for the New England winter months of ice and road salt when the Roadster is idled in my garage (after battery ran down my first winter - seems like a common problem in this vehicle) so I will try to integrate that into the improved grounding solution.
And BTW, the trickle charger works great. The (likely) SKREEM problem occurred when the car was NOT plugged in - I had taken it out to bask in a few days of unseasonably warm weather and the problem occurred after several days when it had not been plugged in.
