Hello, This is my first posting, but very urgent for me.
I have Model 3, two weeks old.
I’m using Nema 10-30 dryer outlet and Tesla adaptor. UMC worked first week without any issue but it stops working from last week. I still could charge with Nema 5-15 (110V). I measured the Nema 10-30 outlet and it shows around 110V. Dryer also not working. UMC doesn’t show any lights.
So, I replaced circuit breaker and outlet to Nema 14-30, and dryer is working now, but UMC still doesn’t show any lights.
This is measurement with Nema 14-30 outlet itself:
- Red+Black: 220V
- Red+Neutral: 120V
- Black+ Neutral: 106-108V
This is measurement with Nema 14-30 outlet with UMC plugged:
- Red+Black: 4V
- Red+Neutral: 121V
- Black+ Neutral: 118V
Tesla Mobile Service came this morning, and tried a new UMC, but still have no clue yet.
Please help me what could be an issue here.
Thanks,
Inigo
