Use an insulation resistor or multimeter to check.
Step 1, use an insulation resistance meter to check whether the insulation resistance of the motor coil is greater than 0.5 megohms. If it is greater than 0.5 megohms, it means that the insulation performance is poor. the engine is good; Step 2, Use the resistance setting of a multimeter to test whether the DC resistance of the three windings of the motor is the same or whether the DC resistance of the three windings has a very small deviation. , this means that there is no short circuit between the coils of the three windings; 3. Step 1: Manually rotate the motor shaft to check for immobility, abnormal noise, etc. ; without load, check whether the three-phase current of the motor is balanced, whether the motor works properly, whether the temperature rises, whether the noise is abnormal, etc. , if the above 4 inspection steps are nomalfunctions, then the engine is good.
Tools to use include 10mm open end, 13mm torx wrench, 17 socket, 19 socket, large. Use the Dafei +19 sleeve to tighten the tensioner pulley and loosen the belt. Use a 10mm Torx wrench to loosen the screw securing the negative battery terminal. Wrap it in a plastic bag to prevent grounding. Use a 13mm wrench to loosen the generator adjustment screw at the top, and use a 13mm socket + mid-flight wrench at the bottom. You just need to loosen it, otherwise the key cannot be removed if it is also tight. Then use a 13mm wrench to unscrew it little by little. To open the dust cover, you need to use a special tool with 32 teeth and a 17-inch sleeve, and use a small air cannon to knock out the one-way wheel. Use a 16 mm sleeve to gradually push the petit bearing. Then assemble the generator step by step and tighten the screws.
The Haval H1 adopts the traditional in-line shift design, which makes the shift operation more direct and smoother. It is also equipped with a reverse error anti-error device to ensure overall driving safety. , F1 racing cars adopt this type of gear shift transmission. The Haval H1 is equipped with paddle shifters only found in high-end SUVs, which improves driving pleasure and safety, allowing you to perform upshifts and downshifts without letting go the steering wheel. But the Haval H1 really isn't pretty. Although the body is not big, it looks very bulky. Unlike Baojun 510, although the body is small, the interior space is designed to be very useful! As for the automatic transmissionatic, driving a car with a manual transmission is called driving!
