What to do if the coolant temperature rise monitor lamp glows in my AirMan Portable Generator?
- F
  fstoneAug 15, 2025
  If the coolant temperature rise monitor lamp glows, it could be due to several reasons. The radiator might be clogged, so try cleaning it. The thermostat or the coolant temperature switch could be faulty, in which case you should replace them. There might be a shortage of coolant, so replenish it. The fan belt may be slipping, so adjust the tension. Finally, check for any looseness or disconnection of wiring or connectors and repair them if needed.

What to do if starter rotates but engine does not start up in AirMan SDG100S-8B1 Portable Generator?
- M
  Mark BoydAug 21, 2025
  If the starter rotates but the engine doesn't start, it could be due to a few reasons. The fuel filter or fuel pre-filter might be clogged, so disassemble, clean, and change them. You may have no diesel fuel oil, so replenish the fuel. There might be air mixing in the fuel pipings, so bleed the air.

Why is my AirMan SDG100S-8B1 Portable Generator generating unstable voltage?
- D
  David YoungAug 25, 2025
  Unstable voltage generation can be caused by several factors. Check and repair any poorly tightened terminals. A faulty AVR could also be the cause, so check and change it if necessary. Reset the function circuit protector (CP) for AVR protection.

What to do if my AirMan SDG100S-8B1 is generating too high voltage?
- P
  Patty PriceAug 27, 2025
  If your generator is generating too high voltage, especially when set at the rated frequency, it could be due to a few reasons. Check and repair any loosened or disconnected wiring or connectors to the AVR. The AVR itself might be faulty, so consider checking and changing it. Also, inspect the AVR variable resistor for broken wires or poor contact; repair or change it as needed.

Why AirMan SDG100S-8B1 Portable Generator even when operated at a rated speed, no voltage or too low voltage generated?
- C
  Cameron WatsonAug 30, 2025
  If your generator produces no voltage or too low voltage even when operated at a rated speed, several issues could be the cause. Check and replace a faulty voltmeter. Inspect and repair any poorly tightened terminals. Examine the generator's main unit for broken or short-circuited winding, and repair if needed. Check and replace a faulty AVR or silicon rectifier. Inspect and repair a faulty exciter, or any broken or short-circuited circuit to the exciter field winding. Ensure the AVR frequency selection switch is correctly set. Finally, reset the function circuit protector (CP) for AVR protection.

What to do if oil fence monitor lamp glows in AirMan Portable Generator?
- M
  Michelle SalazarSep 2, 2025
  If the oil fence monitor lamp glows, it could be because the condensate (fuel, engine oil, and coolant) has accumulated in the oil fence, so drain the condensate. Alternatively, the liquid surface level detecting switch may not be functioning correctly, so check or change it.

What to do if leakage relay lamp glows in AirMan SDG100S-8B1?
- J
  jruizSep 5, 2025
  If the leakage relay lamp glows, it indicates a leakage. Check and repair for leakage on the generator side, the load side, or the connecting cable. If none of these are the cause, the leakage relay itself may be defective, so check and repair it.
