  Brandy HuangAug 2, 2025
  If no indicator lights up when feeding power to the GE Controller unit, there might be several reasons: * **Insufficient power supply:** Verify the voltage level at the power supply terminals with a multimeter to ensure it's within the model's specified range. * **Wrong versions:** Ensure that the relay and ENERVISTA 650 Setup versions are the same. * **Fuse failure:** Remove the power supply, dismount the power supply module, and replace the fuse. * **Loose fuse:** Perform the same steps as for a fuse failure, ensuring the fuse is correctly seated. * **Incorrect wiring:** Double-check that the terminals labeled + and – are correctly connected to the corresponding power source on the 9-pin connector.
