Electric car fault diagnosis are the following nine direction: 5) How to detect brake handle 20 volts with a multimeter to measure the voltage profile controller nine-pin plug, black pen means thin black line refers to the fine red pen purple line voltage? show about 6 volts, the brake is always off zero electric tricycle price, holding about brake handle with electric tricycle shed price and pictures, this time multimeter should show zero price closed passenger electric tricycle, the brake handle constant voltage constant electricity. 6) How to Detect A brushless controller power tube damage detection:? Power Tube bad performance of the vehicle does not turn or phase, specific measurement methods: measuring diode controller files A, B, C three-phase motor wiring multimeter black pen then power red, red pen, respectively, then the three-phase motor phases, multimeter significant value should be around 500-600, if a test result is zero or very small relative to the display, the phase of the power transistor breakdown If the show is a great circuit; the power ground multimeter red pen then closed electric tricycle price Shandong, black pen, respectively, then the three-phase motor phases, multimeter display value should be around 500-600, if the display is zero or very small, the next phase of the tube power breakdown, if the show is a great power tube B in case of a power interruption conduction with a multimeter voltage profile measurement controller nine core plugs Thin Red Line and thin black lines, to see whether the voltage about 5 volts, the voltage controller if not worse. Electric cars: no legitimate source will destroy unity electric bicycle traffic violations, will increase investment in education and punishment according to law, where the bike to break the forbidden line, running red lights, crossed the stop line, into the motor vehicle lanes, sidewalks into special installation cloak etc., should be fined 20 yuan or 50 yuan; who do not meet the standards of electric bikes on the road, all the deduction of 15 days for verification, for legal origin can not provide proof of vehicle to be detained, the unity after the destruction of the public. Electric tricycle price list, the price of electric tricycle, White Dragon White Dragon machinery provided by Shandong Machinery Limited. White Dragon Shandong Machinery Co., Ltd. (www.bailonggrp.com) strong, credible, Shandong Linyi bicycles, tricycles and accessories industry has accumulated a large number of loyal customers.
