Why is the Yamaha EF3800 gasoline generator not working?

Which engine should be started electrically or by hand?

First check whether the gasoline is smooth and the spark is normal

Method: directly remove the spark plug and block the spark plug hole with your fingers. Pull the pull plate several times with one hand, then smell the gasoline on your fingers after removing it.

If so, this proves that the circuit of oil is normal. Otherwise, check the oil circuit (oil switch, carburetor, etc.). Connect the spark plug to the high pressure cap, and connect the high pressure cap to the spark plug. The threads come into contact with the screws or. technical parts of the machine body. Pull the pull plate to check if there is a spark jump at the spark plug, if not, check the flameout switch, high voltage box, spark plug and others circuits. Also, if you can sense itfiring when you plug the spark plug hole with your fingers, if there is a clicking and sucking impact, it is normal. If there is no clicking impact, check the valve clearance, whether the valve is stuck, etc. .

Once these three checks have been completed or cleared, it should be able to start normally

Also, if it is equipped with an oil alarm, you should check if the Engine oil is sufficient. After adding an appropriate amount of engine oil, you can directly disconnect a wire directly under the body to eliminate the oil series fault.

You need to make sure that it is indeed the magneto coil. The problem is still the same. rectifier. Use a 12V light bulb to measure the two white lead wires from the magneto. It is best to have a multimeter. If you measure it at 50V AC, there should be no voltage or about 10.Volts when you step on the accelerator. The bobine. The problem is huge.
