The red flag H9 doesn't turn off when it gets off. Why does it turn off automatically?

Circuit fault, short circuit of low voltage line leads to flameout, and flameout is intermittent. When a device fails, it can be started first, then turned off, then started again, and then turned off. There are many reasons for the sudden flameout of the car, such as circuit problems, spark plugs, ignition coils and so on.

Troubleshooting method of flameout fault

Giving up halfway is not a new topic for beginners. The main elimination method is to improve your driving skills quickly after running-in and use high-quality and qualified fuel. Thoroughly clean the oil circuit, including fuel injector, throttle valve, fuel tank, etc. It may be caused by poor oil quality, too much gum, blocked oil circuit and poor oil supply.

There is too much dust in the air. When the engine is running, a lot of dirt is deposited on the idle spool and throttle seat. When the dirt accumulates too much, the engine will have low idle speed, poor idle stability and idle flameout when driving.
