Issues with charging can result from a number of factors. Before filling out a support request, check the following:
1. Is the plug from the charging station to the Ultium receiver secure? Are the yellow LED’s visible on the end of the charging station?
(For more information on LED statuses for sensors and chargers, refer to the Ultium LED Status & Charging Guide🔗.)
2. Is the power supply (PSU1) plugged into the back of the Ultium receiver? This power supply is what charges the sensors.
3. Is the yellow LED present on each of the Ultium sensors as they are charging? Check to ensure the sensor is facing the correct direction in the charging slot. The sensor LED should face the charging station LED.
NOTE: If the yellow LED is off on the sensor, this indicates that sensor fully charged as long as all other connections are secure. The yellow LED may turn on and off multiple times a day if the sensors are left ON (blinking blue) during a charge cycle as the charging mechanism turns on and off automatically when full charge is detected.
4. If the sensor has been charging for a long time, and the sensor cannot turn on, or the LED flashes red briefly before shutting down, this is an indication that the battery is completely dead and may need to be replaced.
