Temps yesterday when I read the 15.1 volts were in the 40 degree range. The last 6 days have been in that range, prior to that and for about the last month we have been extremely cold, as much of the country was. Highs in the single digits and lows down to -15.
I popped the battery terminal connections off this am and all looked like new. I used of sand paper on them just because I had them off, but not expecting miracles due to the very clean and shiny condition prior. I guess I'll just keep an eye on it and mention it to the dealer if the condition persists into the 50s and above.
Incidentally, the charging system wouldn't be covered under the power train warranty would it?
Thanks for all of your responses.
