Thanks a bunch Phil! That’s good to know about the Tesla so I won’t fret over that. I just asked the great god google on the Bolt and on Reddit was posted that the Bolt wakes up the dc-dc converter when the 12V battery gets low (about 12V) but if the traction battery is below 40% DOD then it does *not* keep the 12 V battery charged. So sounds like it should be ok most of the time while sitting at an airport etc for weeks. I guess they didn’t think of doing that on the Leaf. I’ll recheck the ghost load with the KeyFob away from the car. Might get another solar panel float charger for the Leaf. The Leaf and Bolt appear to have a robust dc-dc converter for running about 10A 120V inverter (100A on 12 V with short jumpers) when the power hours out. The Tesla’s for some odd reason won’t do that or at least in the manual says bad things will happen if you put a high current load on the 12V battery/ dc-dc converter as it’s monitoring for fault currents. Stay Charged, Mark

But if you disconnect the 12v to insert an ammeter, you may need to allow time for the car to settle back to it's sleep state. Also be sure to keep the key fob WELL AWAY from the car. If it's in your pocket during the measurement, there's your problem. On the Model Y, VCFront is responsible for monitoring the 12v battery. If it detects the battery needs a charge it will ask the BMS to fire up the HV and then the whole car will wake up, including coolant pumps, etc. It will then complete the full charge of the 12v, then go back to sleep. I have no experience with the Bolt.
