Does anyone know what's the typical range of the Roadsters isolation resistance (the resistance between the high voltage system and the cars chassis)? The Roadster has a monitoring system that throws an error, if the resistance drops under an threshold value. This value would also be interesting to know. I think it should be somewhere around 500 kΩ... Thanks, Marco
Are you sure it's a resistance figure, rather than perhaps a measured current imbalance between ESS- and ESS+ connections, indicating a leaky path somewhere?
Yes, I think there are no current sensors, that could measure an error current and even if there is a low resistance between HV and the chassis, there doesn't necessarily have to be a leaky current which can be detected by the ESS.. or am I seeing this wrong?
