Overload symptoms Motor overload mainly has the following symptoms:
1. The motor generates heat increase;
2. The motor speed drops, and may even drop to zero;
3. The motor has a low-pitched sound and the vibration is normal;
4. If the load changes drastically, the motor speed will rise and fall;
cause
1. Electrical reasons: such as lack of phase, voltage exceeds the allowable value, etc.;
2. Mechanical reasons: such as excessive torque, motor damage (bearing vibration), etc.;

The overload fault is indicating that your connected load is overloading the generator capacity and it's tripping off. Check your connected load (what ever is hooked up that you're trying to power). You need to use an amp meter to verify the amp draw, and also the rated voltage output. If it's low voltage, could be low engine RPM or voltage regulator. high current indicates a problem with load your trying to power, ie-- Motor or other load.

It could be either your start capacitor or the contactor-relay. Or you could try cleaning the contacts of the relay with an emery board to see if there is a change.

Replace mag pick up. Cranking voltage on the MPU should be at least 2 volts AC. Normally MPU goes out.
You have a bad battery. Replace it, and you'll have a fully functional generator. Trust me; I've been there & done that!

Thanks for your response. I want to clear up one point.
Genset shutdown with no load. The genset breaker is off and it went down
with overload remove load alarm . What can cause that?
This would indicate a faulty overload circuit. Without a schematic I cannot tell if there is an overload device that would cause the fault or an overload circuit that is monitoring the phase current that would cause this. Look for both. There would be a CT (current transformer) feeding a electronic circuit for this, and/or a mechanical type device that would trip on high current.
The circuit that generates the overload fault is faulty if it is tripping with no current and the breaker is open.
