Anonymous users2024-02-15Of course, it is okay not to install it, which was not available on many light vehicles in the past; However, the output voltage of the generator fluctuates with the speed of the engine between 30% and 1800% of the calibrated voltage value of the bulb and battery. In the past, some vehicles were in a high temperature environment in summer, and the charger was easy to burn out when the engine was running at high speed for a long time. In the state of long-term high-current charging, the battery is also easy to be "boiled" dry, shortening the life.
In the absence of a voltage regulator, the brightness of the headlights is very affected by the engine speed, and it is very inconvenient to flicker on and off, and the quality of the bulb is required to be particularly good. These common problems mentioned above are actually the result of the old model not being equipped with a voltage regulator protector.

Anonymous users2024-02-141: The current CG125 coil seems to have 8 coils together and 4 coils together for the ignition coil, is it possible to use it as long as it can be installed? Because the output of the lighting is 12V.
Answer: The current CG125 coil contains lighting coils, ignition coils, and charging coils, due to the limitation of the space position of the magneto, the coils should be placed in sections, and the coils should be connected in series to reach the required voltage.
2: What is the difference between a half-wave rectifier and a full-wave rectifier that masters often say? Because the output is the same, can they all be mixed?
Answer: The half-wave rectifier is to cut off half of the rectification of a complete sine wave, and the other half is not used, for example, the coil generates 12V and the half-wave rectifier is 6V after rectification, and the upper and lower sine waves of the full-wave rectifier are all rectified and 12V. Magnetos cannot be mixed after full-wave and half-wave rectification because they have different phases.
3: I see that some 125 uses 4-wire rectifiers, and some use 5-wire rectifiers, why don't some cars use battery sampling lines? Won't charge the battery badly? Some 5-wire, as long as the sampling line is not through, the battery will be charged!
Answer: The way of connecting power in series is different.
4: As far as I said, if you change the Honda 125, do you disconnect the magneto lighting coil from the wire of the body tie, and then connect the two ends of the coil to the rectifier, and then connect it from the rectifier to the battery, so you can change it to DC lighting? If so, what kind of rectifier is a good one?
If not, why?
Answer: use the magneto to take 12V as the lighting principle: the thick coil on the magneto can output a large current, you can use the wire to lead out all the joints of the thick coil, install the magneto to start the car, use the multimeter to measure the voltage of each line in line with the bulb 12V can be used, if the voltage is not enough, you can connect the coil in series to get 12V, you must think of the head and tail of the coil, that is, the end of the tail.
The battery charging rectifier can use the rectifier tube on the top of the waste car generator, and you can go to the car repair shop to ask for one, and half-wave charging is beneficial to the battery.

Anonymous users2024-02-13The rectifier regulator of the motorcycle is used to control the voltage, and without this rectifier regulator, the voltage emitted by the generator is too high and the light bulb and other electrical appliances will be burned.

Anonymous users2024-02-12There are two main functions of motorcycle rectifiers:
1.Stabilize the voltage supplied to the headlights so that it is not burned out by too high voltage;
2.Voltage regulation for battery charging.
Motorcycle rectifier, also known as voltage regulator, is to charge the battery, and the other is to divert excess current protection appliances.

Anonymous users2024-02-09The voltage regulator is to make the voltage of the motorcycle a little more stable.
Multimeter. Is there electricity in the charging coil plug of the magnetic measuring motor, it is not normal that the charging coil is finished, the voltage is normal to find a rectifier regulator to try it, if it doesn't work, pull out the headlight plug multimeter to measure three wires, there is no multimeter directly take the battery to test, one of the three wires is a ground wire and two far and near rays. If the detection is not normal, unscrew the bulb to check the bulb, the normal bulb is the problem of the headlight tailstock, if you check the above is no problem, then remove the hand on the headlight switch there, test whether the headlight switch power supply line has voltage, the voltage is normal either the switch is not in good contact, or the switch to the headlight line is broken.
Hello, the motorcycle start is very simple, first of all, you have to put your mind right, don't see it as difficult, the more panicked you are, the more difficult it is to operate. >>>More
Motorcycle headlight bulbs can be replaced with 100w ones. >>>More
Since I haven't ridden a motorcycle, a scooter like a car like Qiaoge can do more than 6,000. >>>More
My family bought a Yamaha 125 when it was a few years old, and it was a good ride, and I bought a Wuyang stall. A lot of people say that the cycle gear is better, but I think the five sheep is better than the cycle, it is estimated that I am used to riding the five sheep, this car has been riding for more than ten years now, it seems that there are fourteen or fifteen years, there is no problem, there is a time to ride the car on the one hundred and twenty-three, the engine was burned, the drive shaft was replaced, the engine cylinder was polished on the inner wall and made do with it, and the engine was found to be oil when it was checked. Later, it was replaced with an old wheel, many of these things are used, and they can still be used, but the customer can't say that he won't let him change if he wants to change, and he won't change it with you. We've seen a lot of tires and tubes or other parts that have been replaced by others, and they break down in a few days, and we can still use them for many years.
