I believe there is an easy way to to disconnect the negative terminal without removing the seat, so you can disconnect the batteries and lock it manually before leaving the car parked for long periods of time. You may clamp the solar chargers directly to batteries as well, so you'll have decent charge when you get back. Also, I think the main thing you need to troubleshoot is whether the emergency start mode is operating at all, and whether it's putting the load on the aux battery when needed. Quick google search says you can get the car into "emergency start mode" by cycling the key 1-2 times all the way to left then right and it should start the car by getting a helping hand from the aux battery. If the emergency mode works and it turns on a relay/switch or some sort of solenoid, then it should be putting a load into a rear battery. I guess you just need to study the wiring diagram of the optional aux battery system, and test components using a multimeter to see if everything working. Some scenarios to test: Disconnect the front battery, try to start, and see what happens. Disconnect the rear battery, try to start, observe the behavior and any errors that might pop up Have both connected, but see if it is putting a load to rear battery like in the video below.1 point
