Replace the generator regulator first, and if the problem is not resolved, replace the generator directly
Construction:
Step 1: Remove the negative pole from the battery (very important)
Step 2: Remove the motor protection plate. The generator does not need to be removed. It is very convenient to replace
Step 3: Remove these five screws and remove them. the rear cover of the generator. Among them, 3-4# are rice-shaped head screws. It doesn't matter if you don't have a special rice-shaped nozzle. An inner hex socket is also acceptable
Step 5: Replace it. Install the new one with the new one. Install the fixed wire on the brush before removing it. Don't remove it in advance, remember to resolder pin 3#.
Step 6:YOU. it's done, put the generator cover back on, plug in the negative terminal of the battery, start the car then use a multimeter to measure 14.3v, this is a very standard voltage, problem solved
Hello , try using a battery first. This is usually a battery problem. When using the car, the most common problem is that the battery is discharged. Generally, first check that the battery voltage is between 11 volts and 13 volts. a battery tester to check if it needs to be replaced or recharged. In addition, check whether the generator charging voltage is between 13 and 15 volts after starting, whether it is normal, and check the static power consumption again. (the negative current after locking the car cannot be more than 40mA). If it exceeds, check if there is any problem with the car due to leakage and ask an auto expert. The youProfessional technicians from 4S stores can solve the problem in 10 minutes.
