water gauge water level gauge
The water tank is not water but antifreeze. The water gauge water level gauge will monitor the antifreeze . The dashboard can't be viewed. I send you a picture. In the picture, there is an antifreeze bottle with a circle drawn on it, which is connected to the water tank. If there is something else in this antifreeze bottle, it means that your water tank is full of antifreeze. This bottle is used to circulate the antifreeze back and forth . The liquid level in a cold car drops and the liquid level in a hot car rises. As long as there is antifreeze in the kettle, it's OK.
What's wrong with the water level not displayed on the dashboard? It is the poor contact between the two levels of the battery. There are positive and negative poles on the battery, and there are wire links respectively. The junction is easy to oxidize, resulting in poor contact. The method is also very simple. Use boiling water to heat both poles . Of course , if sandpaper is used to polish the two poles , it is normal , but it takes time and effort . This original method is simple and effective . Then use a screwdriver to lock the screws at the junction . It is better to coat them with butter , which will not be easy to oxidize later . So it is necessary to add a water level gauge on the vehicle .
The ignition system fault can be divided into two cases according to its position in the ignition system: low-voltage circuit fault and high-voltage circuit fault. (1) Common faults of low-voltage circuit: insufficient storage of battery; Poor or disordered wire connection; Poor battery grounding; The distributor or hall sensor is damaged . The ignition switch is damaged or the wiring is poor; The transistor ignition control unit is damaged or the wiring is poor . The diagnosis method of low-voltage circuit fault mostly adopts ammeter or voltmeter to check line by line to eliminate the fault point. (2) Common faults of high-voltage circuit: high-voltage line falls off or leaks electricity . Breakage and breakdown of distributor cover . The distributor is ablated , cracked and broken down . The electrode gap of spark plug is too large or too small . Excessive carbon deposit on spark plug . The insulator of spark plug is damaged.
