The starter is weak when the car is turned on. The starter is weak when the car is turned on. The reasons are:
1. There is something wrong with it. battery. For example: insufficient remaining power, poor terminal contact, poor starter contact contact, etc.
2. The coil is shorted. When the field coil or armature coil is short-circuited, the power of the starter will be insufficient.
3. There is a problem with the bearing. If the bearing is too loose or too tight, the armature shaft will deform, thereby increasing the working resistance and weakening the starter.
4. There is a problem with the collector. When the commutator is stained with oil, the commutator is ablated, the brush spring has insufficient elasticity or the brush is excessively worn, this will cause poor contact.
Let's see how to solve this prproblem.
1. Turn on the headlight switch. If the headlights do not turn on, it means that the battery power is insufficient and the battery needs to be replenished.
2. Turn on the headlight switch. If the light is on, check the electromagnetic switch terminal and the battery terminal, and use a screwdriver to connect the two.
If the electromagnetic switch core does not respond, it means that both electromagnetic switch coils and terminals are unsoldered or the coil is burnt out. In this case. , simply replace the damaged parts.
If the core of the electromagnetic switch reacts, it means that the internal contact of the start switch is bad or the connection of the electromagnetic switch is disconnected. In this case, the disconnected line should be. reconnected.
The contact does not respond andthe relay rings.
If the car ignition does not respond and the relay rings, it may be because the car battery is low or it may be because the motor is not producing electricity or due to insufficient energy production.
If the car battery is discharged, you can use a special tester to check it.
If it is because the generator is not producing electricity, you can use a multimeter to measure the amount of electricity generated by the generator when the engine is running. fire in slow motion. When the engine is idling, the amount of electricity generated should be around 14 volts.
It is worth mentioning that this situation can also occur if there is a problem with the carbon brush of the car starter. If there is no problem with the car battery and generator, you can check the starter,It should be noted that if a problem occurs, it is not necessary to replace the starter assembly, only the starter carbon brush needs to be replaced separately.
After relay failure, the electric start switch contacts will be in poor contact. The main fault symptom is that it cannot start normally. After a relay failure, this may occur. This also causes the gear switch circuit to open, which will prevent the car from driving normally.
Since the iron core in the relay coil is connected to the two connection terminals, the relay will not be damaged once damaged. It is often easy to damage the electrical equipment of the electric start line. (Photo/Text/Photo: Calling the Beast Q&A) @2019
