I took my 2005 Roadster (18k miles) for an afternoon drive yesterday. About 35 miles out the engine died (no noise or warning). I coasted to the side of the road and tried to start it. All dash lights on but it did not click or turnover. Two nice people separately stopped and tried to jump it to no avail. Everything electrical seemed to be working. I had it towed home ($250) since I’ve learned not to mention the word “dealership.” Today I fully charged the battery but it still would not turnover. Is this the RCM issue that I have read about here?
