Thanks Josh.

To confuse the sensor, it seems to me that the sensor would need to be built into the battery lug, so that it was between where we could connect our 12V minus lead and the battery -- i.e., so that our current was going through it. I was assuming it was on the wire side of the battery lug. I haven't seen one of these things, so I must plead ignorance.

Thanks and 73, Jim

Hi Jim,

It's not just hybrid & electric vehicles. Some newer conventional cars shut the engine off during idle to save fuel. There's a sensor inline with the battery neg terminal to measure charge & discharge rates to prevent the start-stop algorithm from causing a dead battery. If you connect direct to the battery, you will confuse the sensor.
