Possible errors / tests:

Motorcycle akumulator voltage measurement, battery exhausted, battery inflated, battery boiling, battery broken, battery overcharged, battery not charging, akumulator charging circuit check, charge current too low, alternator fault finding, coil tower black, coil winding charred, alternator not charging, no battery charging , Generator test, generator faulty, generator test, Lima, alternator test, alternator temperature too high, stator test, stator test check, broken strator defective, anchor plate defective, low light, bulbs burn through, foreign start required, no ignition, motorcycle stops , Current consumers have no voltage, measure charging current, winding interrupted broken by the stator, test exciter alternator,

When the†akumulator strikes

Check the charging circuit
most motorcycles derive the energy for light, starter, ignition etc. from the battery. Without sufficient battery voltage, the vehicles are no longer roadworthy. An empty motorcycle akumulator can have several causes:
Battery defective (position closure)
The battery is not sufficiently charged while driving.
A leakage current (insulation damage) or a consumer draws electricity.

How do I recognize a low akumulator in good time?

The motorcycle†charge indicator light turns on.
The starter turns slowly.
Light gets weaker while driving

fault isolation

First check the battery charge circuit:
Battery poles and + and - cables must not be corroded.
Check connectors of controller and stator / alternator connection. They should be clean and tight.
The cables must not show any signs of breakage, scouring, fire or corrosion.
Check the controller / rectifier for visible mechanical defects.
Always check the complete battery charge circuit! (Even if an error has already been found).

For the following checks, the battery should be charged and in good condition.

Measuring the charging

A measurement of the†across the battery shows if the charging circuit is working properly.
Make the motorcycle battery poles accessible.
With 12-volt on-board electrical systems, set your multimeter to the measuring range 20 Volt / DC.
Connect it to the plus and minus terminals of the akumulator.
For a lead battery, the measurement should be about 12.5-12.9 volts.
Run the engine and increase the speed to about 3000-4000 rpm.
The V+ should then increase depending on the speed to 13.3 to 14.8 volts, but not exceed this value.
If the value is exceeded, the voltage regulator is defective.
The charging†V+ is no longer properly regulated.
Damage to the battery and the electrical system is likely (acid leakage from the battery, burnt out bulbs, etc.)
Voltage peaks also indicate a defective rectifier.

If, despite increasing speed, no increase in the voltage is detected, the alternator probably does not provide sufficient charging current.

A review of the†bike coils†is necessary

Checking the bike coils
1. Alternator with permanent magnet rotor
Permanent magnet rotors work in radial stator / alternators.
By rotational movement of the rotor, a†V+ is induced in the windings of the stator. The rotor is often mounted on the crankshaft journal and runs in an oil bath. Overheating and overloading of the regulator will cause defects.

Check the AC†from Stator

Disconnect the†the bike coils†cable from the regulator / rectifier.
Measure the AC†directly at the alternator (measuring range up to 200 V AC voltage).
Connect two contacts of the alternator connector to the probes of your multimeter.
Measure the voltage between 2 plugs of the alternator at a speed of 3000-4000 rpm. Measure all 3 lines against each other and compare the voltage values. Stop the engine between measurements. The voltage values will be between 50 V - 70 V. Highly deviating measured value indicates a defect.

Testing of the†Stator on ground fault and resistance test

If the bike coils†V+ is too low, a short to ground or a break in the winding may be the cause.
Resistance measurements can be used to detect the errors.
Perform an ohm measurement with the ignition off. Connect multimeter minus cable to ground and measure with the other probe all contacts of the connector of the alternator. The resistance measurement must be infinite (no passage). If a resistance is measured, the stator has a ground fault and is defective.
As next resistance measurements, the contacts (coils) are to be measured against each other. The measured resistance should give similar values for all 3 measurements. Usually under 1 ohms (see details in the Werstatthandbuch). Different measurements eg. 0 ohm means short circuit and at higher resistance value than the other comparison measurements indicate au

1st measurement

The field windings by resistance measurement. Connect the measuring strip before and after a field winding. The measured values should have similar values (less than 1 ohm, compare the measured value with the original value from the workshop book). If the measured value is too high, there is an interruption.
2nd measurement
Select resistance measurement in high ohmic range and keep the + test probe on the stator winding - connect the test probe to ground. Measured value must be infinite. Otherwise, the motorcycle stator has a ground fault.
3rd measurement
Resistance measurement between the collector blades of the rotor. Measure all slats against each other. Measured value approx. 2 - 4 ohms. Compare measured values with details from the workshop manual. At 0 ohms - Short circuit, measured value too high - Interruption. If there is a rotor defect, replace it.
4. Measurement
Select a high ohm range for the rotor resistance measurement, + hold the strip from the multimeter to the respective collector lamella and the line to ground (eg axis). Measured value must be infinite. Otherwise, the stator has a ground fault. Rotor is to be replaced.

Collector generators mounted on the crankshaft stump uncover.
First disconnect the battery!
Check collector, rotor and stator. Too little stator / alternator power can be caused by defective pressure springs, worn out coals or a fouled collector. If the collector is wet or oily, check the seal.
The rotor windings are tested by measuring between the copper tracks of the collector (measured value approx. 2 - 6 ohms). Verify measured value with details in workshop book. Measured value 0 means short circuit, if the measured value is too high there is a winding break. The measurement against ground must yield an infinitely high resistance. Otherwise, there is a ground fault.
Just as described with external collector generators, the stator windings are also measured for continuity and grounding at the cable connections in this design.
