2. My Tesla is not charging using a Gen 3 Wall Connector Single Phase
If you are using a Gen 3 Wall Connector and you notice that your Tesla is not charging you should have a look at your owner’s manual to troubleshoot the charging problem.
Tesla Gen 3 Wall Connector has a light bar to indicate the whether the vehicle is charging or not. The light bar has red codes which blink and pause and then repeat several times to indicate which kind of charging fault your vehicle is experiencing.
Here are some faults, their causes and fixes.
1. The light bar does not light up.
The charging is disabled and your Tesla is not charging because you have a power supply issue.
Fix 1: Confirm that the power supply is turned on. Check your mains or if there is a black out wait for power supply to resume.
Fix 2: If the issue cannot be fixed with the resumption of power, call a qualified electrician to detach the Wall Connector from the wire box and verify that there is voltage at the terminal block using a multimeter.
Your electrician should log the voltage readings for the following: L1 to L2/N, L1 to Ground, L2/N to Ground.
2. Light Bar turns solid red
Your Tesla is not charging well because your Gen 3 Wall Connector has an internal problem.
Fix 1: Power cycle Wall Connector. Turn off the circuit breaker, wait 5 seconds, and turn it back on.
Fix 2: If solid red light still remains, write down the part number and serial number and then contact Tesla Energy.
3. Light bar has one red blink
Your Tesla is not charging appropriately owing to a ground fault circuit interruption arising from unsafe current path.
Ground fault circuit interruption (GFCI) can help thwart electrocution. If a your body starts to have a shock, the GFCI detects this and switches off the power before you can get hurt.
Fix 1: Examine the Wall Connector, handle, cable, and vehicle charge port for damage or signs of water entry.
Fix 2: Have an electrician assess that ground is not directly coupled to a conductor wire in the branch circuit.
4. Light bar has two red blinks
Your Tesla is charging is limited or not happening at all as it should on account of ground assurance fault and/or high ground resistance.
Your Gen 3 Wall Connector constantly tests for the presence of a safe ground connection and routinely recovers from faults.
Grounded assurance runs by injecting a small quantity of current into the ground conductor with the intention of calculating the impedance(resistance) between line and ground.
Fix 1: Verify that the Wall Connector is properly grounded. The ground connection must be bonded in the upstream power supply for correct operation. Check all physical connections, including the Wire box terminals, electrical panel(s), and junction boxes.
Fix 2: In domestic power supplies, examine the bond linking the ground and neutral at the main panel. If connected to a transformer, get in touch with the transformer’s manufacturer for direction on how to bond the ground connection.
5. Light bar has three red blinks
Your Tesla is charging minimally or not charging as a consequence of high temperatures.
Fix 1: Validate that your Wall Connector is connected to Wi-Fi and updated with the latest available firmware for optimal temperature sensing functionality.
Fix 2: Test the faceplate and cable handle for excessive warmth.
Fix 3: Have an electrician disconnect the Wall Connector from the wire box and inspect that the conductors used are sized correctly and that the terminal block is torqued to specification.
6. Light bar has four red blinks
Your Tesla is not charging appropriately because the online features disabled as the Internet connection is lost.
While the wall connector can charge without internet you will need a Wi-Fi connection to communicate to the charger the right rating of your breaker so it can charge at the appropriate rate.
Fix 1: Check for objects that could hinder with the area’s Wi-Fi signal strength. Remove them or change router position.
Fix 2: Confirm that the local Wi-Fi router is functioning.
Fix 3: If the Wi-Fi password was changed lately, follow the commissioning process on your phone to update the Wi-Fi settings.
7. Light bar has five red blinks
Your Tesla a power-sharing communication problem which leads to a reduced charging rate. Power sharing is a firmware feature that permits up to six Gen 3 Wall Connectors to share power and charge many Teslas at once.
Fix 1: Check for items that could restrict the area’s Wi-Fi signal strength and eliminate them from the vicinity.
Fix 2: Follow the commissioning process on your mobile device to re-link the Wall Connectors for power-sharing.
8. Light bar has six red blinks
Your Tesla is not charging properly as a result of an overvoltage or deficient grid quality.
Fix 1: Authenticate that the power supply is around 200-240 volts.
Fix 2: If the issue continues, have an electrician detach the Wall Connector from the wire box and check that voltage readings are as they should be at the terminal block using a multimeter. Keep count of the voltage readings for the following: L1 to L2/N, L1 to Ground, L2/N to Ground.
9. Light bar has seven red blinks
Your Tesla is not charging as there is a vehicle overcurrent.
Fix 1: Lower your Tesla’s charge current setting.
Fix 2: If the issue does not resolve write down the VIN and approximate time of the fault and call Tesla.
