  If your Hyundai Portable Generator's diesel engine won't start, several factors could be at play. First, ensure the governor lever is in the START position. Check that the emergency STOP button isn't activated (depressed) and reset it if it is. Insufficient fuel could also be the culprit, so refill the fuel tank. Additionally, verify the engine oil level, ensuring it reaches the upper lever. Other potential issues include a faulty fuel injection pump (test it after removing), carbon build-up on the injector (clean it), a slow-turning start motor (check battery performance and connections), or a flat battery (charge or replace it).

  If your Hyundai Portable Generator isn't producing power, start by checking if the main breaker switch is turned ON. If not, switch it ON. Other potential causes include worn alternator brushes (replace them), poor contact in the socket (ensure plugs are fully inserted), an incorrect rated speed (adjust engine speed to produce 52 Hz with no load), or a damaged AVR (replace the AVR).

  If the Hyundai Portable Generator's diesel engine fails to start, check if the governor lever is set to the START position. Confirm that the emergency STOP button is not activated. Ensure there's enough fuel in the tank. Also, verify the engine oil level is at the upper lever. Other potential issues include a faulty fuel injection pump, a carbon-filled injector, a slow start motor, or a dead battery.
