Any time in the past when I've disconnected the 12v battery, everything shuts down. Even if the inverter is humming along charging the battery like it does every 4 hours or so for a minute, disconnecting the battery instantly results in everything shutting down. If the contactors are engaged, they click off.
Well no more. My 12v battery is getting a constant 13.8 volts 24 hours a day. If I disconnect it, the MCU stays and the doors remain functional. Odd thing is even though the 12v battery is constantly being charged, the inverter hum is completely gone. Even stranger, disconnecting the 12v battery results in no alert of any kind. Super strange.
If I pull the high voltage loop with the 12v battery connected, the contactors click off and the 12v battery reads 12.7 volts.....as you would expect.
I just did the MCU2 upgrade. Did they add a small charge inverter to keep the battery always charging and leave the contactors engaged all the time?
Can anyone else with MCU2 measure their 12v voltage? I measured mine at the battery with the frunk tub out which it has been for the last 24 hours.
Full disclosure, this weekend I started getting BMS contactor alert errors. Could this be related? Although they're not stuck on. If I pull the high voltage loop the contactors click off.
