    What to do if the AirMan SG starter rotates but the engine doesn't start?
    • R
      Robert MartinAug 16, 2025
      If the starter of your AirMan Inverter is rotating, but the engine isn't starting, there are several potential causes. It could be due to a clogged fuel filter, which requires disassembling, cleaning, and changing the filter. Another reason might be a malfunction of the controller, in which case you should check the fuse. Also, check if there is diesel fuel oil and replenish it if needed. Finally, air mixing in the fuel pipings can cause this issue, so bleed the air.

    How to fix an AirMan Inverter that generates no voltage even at rated speed?
    • C
      Carol NguyenAug 19, 2025
      If your AirMan Inverter generates no voltage or too low voltage even when operated at a rated speed, several issues could be the cause. Check and change the voltmeter if it is faulty. Ensure terminals are properly tightened. Inspect and repair any broken or short-circuited winding of the generator's main unit. Check and change the AVR if it's faulty, as well as the silicon rectifier. Inspect and repair the exciter and any broken or short-circuited circuit to the exciter field winding. Reset the circuit protector (CP) for AVR protection.

    Why does the coolant temperature rise monitor lamp glow on my AirMan SG?
    • D
      Daniel SchultzAug 22, 2025
      The coolant temperature rise monitor lamp on your AirMan Inverter may glow due to several reasons. The radiator might be clogged and needs cleaning. The thermostat or coolant temperature switch could be faulty and require changing. There might be a shortage of coolant, so replenish it. A slipping belt needs tension adjustment. Also, check and repair any looseness or disconnection of wiring or connectors.

    Why is the AirMan Inverter generating too high voltage and the voltage regulator knob isn't working?
    • A
      Alexa WalkerAug 31, 2025
      If your AirMan Inverter is generating too high voltage, and the voltage won't drop even when adjusting the voltage regulator knob, check and repair any loosened or disconnected wiring or connectors to the AVR. A faulty AVR could also be the problem, requiring a check and change. Additionally, inspect and repair or change a broken wire or poor contact of the AVR variable resistor.
