The solution to the problem that the generator generates electricity only with a neutral wire but no live wire is as follows:
1. Connect the other two phase wires: the generator output end is only connected. with one phase wire and one neutral wire You can try connecting the other two phase lines so that the output end of the generator is connected to three phase lines and one neutral line. This ensures that the generator output voltage waveform is complete and meets electrical safety standards.
2. Use an automatic voltage regulator: In order to ensure the stability and accuracy of the generator output voltage, an automatic voltage regulator can be used for adjustment. The automatic voltage regulator can automatically adjust the output voltage according to load changes and grid voltage fluctuations toguarantee the stability and precision of the tension. At the same time, the automatic voltage regulator can also detect whether the wiring is correct, avoiding the problem of improper wiring.
1. First check whether the engine oil and gasoline are newly added. Otherwise, they have been added for more than three months and the oil and gasoline need to be drained and replaced. Since engine oil and gasoline are only valid for three months, oil and gasoline used for more than three months have lost their viscosity and have no effect.
2. It is difficult for old gasoline generators to ignite. The reason is that the spark plugs have carbon deposits. They either have to clean them or replace them with new ones. too dirty, resulting in lack of air. To clean or replace. If the engine oil has melted, because if the machine is not used for a long time, the engine oil mustbe drained, and whether the gasoline is qualified and has evaporated, resulting in insufficient purity. Difficulty igniting.
3. Check whether the starting method is correct, such as whether the oil switch is on, whether the shock absorber is closed when the cold engine starts for the first time, whether the starting method is correct, and whether the starting method is correct. startup has been achieved. Rotational speed, etc., then troubleshoot in the order of first checking the oil circuit, then checking the circuit, then checking the cylinder compression. First, turn on the crankcase oil drain switch, quickly pull the engine and identify the faulty area by observing the oil flow. If no or little oil flows from the oil switch, the mixture is not entering the cylinder or is too thin. If there is a lot of oil leaking from the oil switch, it means thatthe mixture is too rich. The reason may be that there is a problem with the oil supply system or the starting method is incorrect.
4. Remove the high voltage wire from the spark plug and test for fire: if there is no spark or the spark is very weak, it means there is a fault with the magneto or high voltage. thread ; If the spark is strong, it means there is a fault with the spark plug or the cylinder is leaking and the mixture is poorly compressed. Next, check or replace the spark plug. If it is confirmed that the spark plug is functioning normally, further check the compression condition of the cylinder. Poor mixture compression in the cylinder may be due to a leak in the cylinder or a leak in the crankcase. The location of the leak can be detected through external inspection. If the air leak is caused by excessive mounting clearance (such as mounting clearance between piston and paking of the cylinder or various parts of the piston ring, etc.) or damage to the parts, the machine should be disassembled and inspected. For some magneto and multi-cylinder gasoline engines using battery ignition systems, after setting the stage gap and angle, it is necessary to check and adjust the ignition timing and correct the sequence ignition, because if the ignition sequence is disturbed, the machine will not be easy to start.

5. It is difficult to start a gasoline generator and new machines require some time. This is the break-in period, so the longer the generator is used, the better. A qualified generator is not worn out, but damaged, so it is better to start the generator 1-2 times a month.
