If you have some fundamental electrical training/experience.

Undervoltage 1902
ALARM
Fault is displayed when both zero crosses are missing from the controller's input for 1.5 seconds or more. Could be a faulty excitation winding, zero cross circuit, loose wiring, or field boost hardware problem. Same applies here, v1.12 or later firmware should be installed.

Guardian generac 10kw model 5502 does not output correct voltage


the instructions says the voltage regulator is automatic/digital. when you check the voltage is there any load on the generator? if applying load to the generator doesn't help, you can manually change the motor speed where the governor connects to the carborator, but it may change the frequency, but the regulator may fix it
