First: My sincerest thanks to all of you as I have spent countless fascinating and enjoyable hours reading the Roadster Forum posts which have been profoundly informative. Special thanks to the gracious and knowledgeable ecarfan for sharing the 2008 Owner's Manual pdf and several helpful tips, and to rock star Henry Sharp for the amazing Can JR which works perfectly with my Clipper Creek HCS-40 charging station and a number of free public chargers here in the California wine country. I will have a few questions for the collective wisdom of the group and will start with the most "urgent": The car was throughly checked out by the Tesla Service Center in Burlingame before purchase and they replaced the (single I believe) PEM fan which had a service alert and did a full service and gave the vehicle a very clean bill of health. The original owner drove it only 845 miles and kept it plugged in. The battery charges to 181standard/210 ideal - consistent with the PlugInAmerica survey data suggesting that, at least to date, Roadster battery capacity is primarily related to mileage/recharge cycles rather than age. I don't know the CAC yet but that will be interesting to see and I will get it soon. It drives like a dream. My first 2 questions: 1- The car makes many continuous (never-ceasing) sounds while charging, ranging from a soft whirring in the rear to loud and very loud fan sounds intermittently. That was not too surprising or concerning, and it charges exactly in line with expected " time specs" based on the current I use. However I have been surprised that the car continuously (again, never ceases) to make a soft whirring sound even when not charging. It is in the rear/PEM area and is soft and pleasant, but ever-present. Whatever is going on, it does not seem to deplete the battery much if at all even when the car is unplugged overnight. And the the car performs magnificently in every way with no warnings or alerts. It has been a bit warm in the wine country this week with ambient temps in the 90s but my garage is 75-77F. So, is continuous never-ceasing whirring normal at 75-77 degrees F ambient temp, even when not sharging? If so, is it likely a hidden PEM fan whirring or the battery coolant circulating, or both? 2- I will be in Asia for about 6-8 weeks soon and my wife will not drive the car. I will keep it plugged in and of course in storage mode. Which charger would be the best of my 3 options: The MC-120 Level 1, the MC-240 Level 2 (30A output) or my Clipper Creek HCS-40 (32A output)? The car did come with a brand new and very robust-looking TS-70 HPWC (Tesla branded but made for them by Clipper Creek) but I don't think I'll install it as I should rarely if ever need a really quick charge at home. Many thanks for any thoughts on these questions and once again thanks for the wealth of info, experience, and insight that you have all contributed to the Roadster Forum over the years!
