I just had the gen 3 wall charger installed for the model y and I noticed a message saying low quality grid detected. I tried unplugging and replugging the charger in. The amps will fluctuate from 0 to 13, starts to climb, and drops to 0. Eventually it will hold at 32 amps and never hit the 48 amps. Just wondering if anyone else experienced this problem and how you resolved it. Thanks in advance.
