Checking The Charging Voltage - ProCharger 10037598 Mode D'emploi

7.5 | Checking the charging voltage

1. Tapping starts the test. Automatic testing of the open circuit
voltage follows, before the voltage is tested further at an
increased speed.
2. To test the voltage at an increased speed, it must be increased
as listed below and maintained for 3 to 5 seconds. The test is
then complete.
1-4 cylinders: 2,500 rpm, 6 cylinders: 2,000 rpm
8 cylinders: 1,600 rpm
3. Result of the charging voltage test
Charging voltage: normal
The alternator's output voltage is within the normal range. No
problems were detected.
Charging voltage: low
The charging voltage is low. Check whether the engine
transmission belt is slack or has a missing connection and
whether the alternator and battery are properly wired to one
another. If the belt connection and wiring are correct, follow
the vehicle manufacturer's recommendations to eliminate the
possibility of defects on the alternator.
Charging voltage: high
The alternator's output voltage is too high. Because most
motorcycle engines have an integrated regulator, the alternator
must be checked and replaced if necessary. (The regulator can
be replaced directly in older vehicles with an external regulator.)
The regulators' voltage range is generally is 14.0-14.7 V
±0.5 V depending on the battery type recommended by the
motorcycle manufacturer. If the charging voltage is too high, the
battery will be overcharged, resulting in a shorter service life or
malfunctions.
No voltage output: no voltage output detected at the engine
Check whether the alternator's cable and belt are in proper
condition.
