Test machine is a very important step, specific checks as follows: 1. Crank crank to make the oil nozzle. Nozzle crackled as described injector plungers and vice performance is still good; if the room is not round, "Wow" and other abnormal sound generator controller customized Guangdong, then wear the gear is not serious. 2. Pulled down the flywheel generator controller factory in Guangdong, without sound, indicating that the gap between the crank shaft and bearing little stem. 3. Pull turn the flywheel, the piston near the bottom dead center, then from side to side of the flywheel, if no "blah" sound, indicating wear rod axis between the stem and the tile is not serious. 4. The cylinder pressure, crank crank, when removing the vacuum generator controller factory in Dongguan, such as piston big rebound, rapidly rotating flywheel, indicating cylinder, piston, piston ring wear small. When crank crank, oil pressure gauge pointer should not be less than a red label instructions or oil can quickly rise, men pressure should be effortless. 5. Start the machine. As easy to start, colorless or light gray smoke generator controller, speed and stability without noise, indicating that the technical condition of the old diesel engine is good. When the electric vehicle controller brushless controller did not output a) referring to the main phase brushless motor controller check the measurement chart, with a multimeter DC voltage + 50V stalls, 6-channel MOS transistor to detect whether or not the gate voltage and the turn of the rotation angle was correspondence. 2) If there is no right, indicating that the controller in the PWM circuit or MOS tube drive circuit failure. 3) the main phase brushless controller reference checks, and whether or voltage measurement chip input and output pins and turn the rotation angle has a corresponding relationship, you can determine which chip is faulty, replace the same model chip can troubleshoot.
