Hi All,

I bought MY on 01Jul2020 with VIN 015xxx (yes, bad luck as I bought the car $3k more expensive, but am taking it in the stride!) . With the NEMA 14-50 not yet installed, I was charging car with 5-15 outlet with frustrating charge times after long trips, but took it in stride as well! The car used to charge at 12 A and usually displayed "12/12A.... 119 volts". Once charging was complete, it displayed "0/12A.... 0 volts"

I had assessment done while remodeling garage and I rrealized my garage had guage 12 wires and 20 amp breaker, so installed 5-20 wall outlet and ordered 5-20 nema adapter from tesla website. The car now charges upto 7 miles an hour. I get about 85 miles charged overnight, which is way more than enough for my daily run! Also I keep the car at 80% max charging and frequently charge the car, as I want to keep a low "depth of discharge" that should enable the battery to last 10-12 years or more with my usage. While charging, the car goes upto "19/16A" (yes, nineteen A) current for a second then goes down to 16, and displays something like "16/16A.... 119 volts". My question is: when charging is complete, the car displays "0/16A.... 2 volts". I am confused why the car displays 2 volts with 5-20 adapter while it was displaying 0 volts with 5-15 adapter upon successful charging? Is there something to worry about?

Second question? Do these cars "eat up" electricity even after completely charging, and while plugged in. I noted that my car would lose 1 mile range every 8 hours of so if disconnected from mobile connector and in "parked" mode.

So why does my car show 2V and decreases a mile of range every 8 hours or so? Sometimes I have even noted occasional hum when car is locked, parked and no one is inside the car, then the sound stops!

Advice would be greatly appreciated, thanks in advance!
