Troubleshooting Alerts
• The building wiring, including any wall outlet used with a Mobile Connector.
• The electrical connection to the power utility line where it enters the building.
Discuss with the electrician whether the charge current on the vehicle should be lowered, or if the installation should
be upgraded to support a higher charge current.
As this alert is usually specific to external charging equipment and power sources, and it does not typically indicate
an issue with your vehicle that can be resolved by scheduling service, it is recommended that you:
• Try charging with multiple, different types of charging equipment at different locations.
• Contact an electrician to inspect the wiring and equipment at your normal charging location.
You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can
be located through the map on your vehicle's touchscreen display. See
details. Additional third-party charging stations may also be available in your area to help you to pinpoint the issue.
For more information on troubleshooting Mobile Connector or Wall Connector status lights, refer to the product's
Owner's Manual at Charging & Adapter Product
manufacturer's provided documentation for troubleshooting tips.
(PCS_a054)
Charging stopped due to large voltage drop
Remove extension cords / Have wiring inspected
Charging has been interrupted because the onboard charger in your vehicle has detected an unusually large voltage
drop.
Likely causes of this issue include:
• Problems with the building wiring and/or the wall outlet.
• An extension cord or other wiring that cannot support the requested charge current.
This issue can also result from turning on electric devices that draw a lot of power from the same branch circuit
while the vehicle is charging.
If this issue has occurred multiple times at your normal charging location, contact an electrician to inspect the
electrical installation. They should check the following:
• Any installed charging equipment and its connection to the building wiring.
• The building wiring, including any wall outlet used with a Mobile Connector.
• The electrical connection to the power utility line where it enters the building.
Discuss with the electrician whether the charge current on the vehicle should be lowered, or if the installation should
be upgraded to support a higher charge current.
