CHARGING SYSTEM:
The mission of the system to load a motorcycle,
converting mechanical energy (movement engine) into electrical energy. The latter is to be used to charge a battery, which will provide the necessary power to all electrical equipment.
elements necessary for such conversion are: an alternator, a rectifier and a
voltage regulator. Any of these parties may fail and when it does
various anomalies are observed.
To determine where the problem, we must do some tests and we'll
a voltmeter that responds to effective or true RMS value, since a common tester would give false indications.
Voltage Typical values \u200b\u200bare:
nominal battery voltage with the engine off, contact closed and lights off, more than 12 volts and less than 13 volts. nominal battery voltage
tension is measured at the battery terminals when the motorcycle is stopped, out of touch
and Lights The first step do is check the battery nominal voltage. If you measure below the above, we can assume that there is a problem:
.
battery.
voltage regulator. electrical installation
As a first measure is to withdraw from the bike and load it with an external charger. Once loaded, we return to perform the measurement and you put a 55W lamp. We observe that the voltage will quickly drop to 12v and then will remain in this tension for a period.
If this happens we can say that the battery is good and the discharge was caused by another reason
. If we find that the tension does not stabilize in the 12v needs to be replaced.
In conclusion, so far only been able to verify the status of the battery.
BATTERY CHARGING VOLTAGE (MOTORCYCLE RUNNING)
1) Turn the engine running, leave it idling, measure the voltage on battery again and take notice.
2) Accelerate the engine up to 5000 RPM and note in this condition.
3) Compare the values \u200b\u200bwith the graph that follows.
Chart, green line shows a normal and correct operation of the charging system. Tension battery is kept on until the alternator begins to exceed the battery voltage and start charging, to the point where the controller begins to limit the voltage to not generate excessive load. Blue In
shows a load fault condition, the battery powered the
alternator, this may be due to a fault in the alternator (broken wire or short) or a failure in the rectifier or the regulator. Given this situation should be reviewed by both parties as the wiring that links them. Damage caused
: None, but inevitably drain the battery and the bike will not start
.
In Red shows a situation of excess load. All energy generated by the alternator
provided to the battery and charges, in an uncontrolled manner, the controller fails.
Damage may occur: burning lamps
serious damage to the battery.
And worse, damage to electronic systems, cdi, etc
The voltage regulator should be replaced.
Summary:
With rated voltage measurement to validate the status of the battery.
By measuring validate charging voltage regulator.
Finally, if the problem persists you should check the electrical installation alternator included.
The alternator can cause overload problems. On failure
only causes problems for lack of cargo.
