Good point. Back to future. I’m looking for flux capacitors…No problem
Seriously, two different observations. Current monitoring from Tesla Service menu. Display not identifying where the current draw from. In this case 12v and HV connected as normal. Selected power down from menu with everything turned off with butt in drivers seat.
Second observation. After disconnecting 12v terminal from battery, I rubber bagged the positive terminal and disconnected the HV contractor. In this case, I had already powered down the car on the safety menu. I observed the lights behind the dashboard at the computer (red colored) were still illuminated. I presumed a secondary power source as small guage pink wire from battery through firewall along the passenger side floor panels to near penthouse (HV connector) was continuously powered. I didn’t have my clamp ammeter to capture the current at various locations. Next time I’m gonna repeat the same conditions to determine the circuits running with and without normal connections of low and high voltage circuits.
I want a baseline of voltage and current loading off the 12v battery before installing a rear amp to power subwoofer and/or rear deck speakers.
