Solution

1. Preparation

Ensure the vehicle is parked safely and is in "Park" mode.
Disconnect the charging cable from the vehicle and the power source.
Gather tools: multimeter, flashlight, and a replacement charging cable if necessary.

2. Inspect Charging Cable

Visually examine the charging cable for cuts, frays, or other damage.
Use the multimeter to check continuity in the cable. If it is damaged, replace it with a new Tesla charging cable.

3. Check Charging Outlet

Verify that the outlet is operational by testing it with a different device (like a lamp).
If using a dedicated circuit for the charger, inspect the circuit breaker to ensure it has not tripped; reset it if necessary.

4. Reset Home Charging Station

Turn off the power to the charging station at the circuit breaker.
Wait for about 30 seconds and turn the power back on.
Reconnect the charging cable to the vehicle and check for functionality.

5. Inspect Vehicle Charging Port

Use a flashlight to inspect the charging port on the Tesla for any debris or damage.
Clean the port gently with a soft cloth if dirt or obstructions are present.
