How to deal with common motorcycle breakdowns (Part electricity)?

 Motorcycles are used as an easier way to navigate cities and villages being smaller than cars, bikes are made up of mechanical and electric parts that cooperate together to operate and control them, and may experience breakdowns over time since their use, 

so in this article we will present the principle of the functioning of electric parts in the bike and the malfunctions that affect the electrical parts, along with the way to ensure their safety.

How to deal with common motorcycle breakdowns (Part electricity)?

Working Principle Electric Motorcycle Parts:

The work of bicycles depends on the validity of power from the battery to its electric parts, such as the start drive, operating system, fuel injection system, electric additions, which consumes its power, and the bicycles have a battery charging system, consisting of alternating electric generator Alternator that charges the battery while driving the motorcycle, bringing the output current from the generator to the voltage regulator (Regulator) and Rectifier, which will turn the alternating AC into a one-way continuous current, to cross through electronic/diode pulses (Diode) that allows one-way current to reach the positive voltage to the battery.

Alternator Principle:

The generator is the cornerstone of the charging system, it controls the flow of current from it based on the controller (Thyristor) which extinguishes and operates it through readings delivered from the voltage sensitization circuit. When the readings from this circuit reach a certain threshold, the generator control rectifier operates and connects it to the stator coils for grounding and overcurrent disposal, and when the current in the circuit decreases the generator recycle operates again.

Electrical parts malfunctions and handling methods:

The power failures in the motorcycle vary according to the part that is affected by the malfunction. The method of maintenance varies according to the broken part. The repair of the battery failure is different from the failure of the electric valve or grounding wire. This applies to the other parts of the bike. The following is a mention of the problems affecting each part and the way in which they are handled:

    1. Battery

  • The battery is the main power source of the bike and it suffers many breakdowns, and its safety and failure-free can be ascertained by paying attention to the following:Ensure that the battery is fully charged before running the bike, it must be charged by 12 volts when the bike is extinguished, and the lack of high reading voltage in the battery of 10.5 volts indicates damage to one of the battery cells.
  • Ensure that battery charging is not rapidly lower than full charge at the start of its operation. A lower than 10.8 volts of capacity indicates battery damage and the need to change it, or problems with the engine that leads to rapid consumption of its power, and high battery wire heat.
  • Ensure that the voltage in the battery does not exceed 14.8V after charging so as not to be damaged.

    2. Main Electric Valve

Damage to the main valve causes the parts of the electric bike to stop working or to operate intermittently and indiscriminately, and the problem of damage can be dealt with by following the following:

  • Keep a backup electric valve in the bike, to replace it when it is damaged, it is damaged over time and sustained vibration.
  • Inspect other electric parts in the bike, and make sure they are not produced for a high-volume current that burns the valve.

    3. Grounding Wire

Grounding wires have some problems, which is one of the problems of electric bikes that is easy to treat, and the following points to their disruption:

  • The bike stopped working altogether.
  • Electrical parts stop working, or work intermittently. 

    4. Stator file

A problem with battery charging indicates that there is a failure in the stator, it is part of the battery supply system of the current needed to charge it as well, resulting in rapidly running out of capacity, and its safety and problem free can be ascertained by following the following steps:

  • Separate stator wire from battery.
  • Bring a digital multimeter (multimeter) and place it on the OEM setting.
  • The ends of the scale are connected to the ends of the fixed wire, starting from the first end with the second, the second party with the third, and the first party with the third, as the reading should appear at each of these times 1 ohm and not exceeding 1.5 ohm to make the stator intact.
  • The red scale tip arrived with stator wire, and the black tip reached with the negative pole in the battery, provided that no reading is shown on the scale to indicate that the stator is free of grounding failures.
  • Calibrate the scale setting to AC Voltage resistance.
  • Run the bike up to its engine speed to 2000 rpm.
  • Measuring voltage between stator limbs again as in the third step using the multiple scale, with the numbers showing convergent in the three attempts to indicate its safety.

    5. Regulator/Rectifier

The rectifier converts the next rotating current of the regulator into a continuous current to charge the battery well. The regulator ensures that the amount of current is suitable and does not exceed a certain limit to protect the battery from damage, by converting electric power into heat power that is disposed of by air, they can be assured of failure by following the following steps:


Follow the following steps to make sure the rectifier is safe:

  • Separate the wires from the current rectifier.
  • Put the digital multiple scale on diode mode.
  • The positive scale tip is connected to the positive rating diode, the negative scale tip is connected to both ends of the stator separately, and no reading must appear both times to be intact.
  • The negative scale tip has reached the positive Valuation Diode, the positive scale tip has reached both sides of the stator separately, and the appearance of any reading on both occasions will indicate the correctness of the rectifier.
  • Repeat the previous two steps of the negative rectifier diode, with readings appearing in the inverse position, i.e. when the tip of the positive scale reaches with the negative diode only to indicate its integrity. 

        Voltage Regulator: 

Track the following steps to ensure the safety of voltage regulator:

  • Multi-scale mode on voltage measurement mode
  • The tip of the gauge reached the battery after the engine's operation, and the reading should not exceed 14.5 volts and should not be less than 13.5 volts.

    6. Ignition spark generator, wire and surrounding sheeting

The wire reaches the generator ignition system with coverings, and it must be inspected to ensure their safety. The wear and tear of the insulating material around it causes the wire to obstruct, or the coverings may break down, rust the wire and open the electrical circuit and thus hinder the passage of the current.
