When you perform these procedures yourself, be sure to always follow the

safety instructions for using the unit (see user instructions); model-specific

details and target measurement values can be found in the repair and

maintenance manual for your particular vehicle. While we have carefully

researched all the instructions and reviewed them several times, you will

understand that we accept no liability.

1. Check charging circuit

The charging circuit ensures that there is a power supply to the battery and all

consumers (ignition, lights, etc.) on the bike.

- If there are indications that the alternator is not charging the battery sufficiently

(e.g. the headlight is dimming or the battery charging indicator light is flickering),

start with a visual inspection of all the accessible components of the charging

circuit: plug connections should be secure and clean, cables must not show any

sign of damage, wear or fire, the alternator and regulator/rectifier should not

exhibit any obvious signs of mechanical defect.

- To test the individual components further the battery should be in good

condition and fully charged.

- If you identify a fault in part of the charging circuit, also check all the other

components of the circuit for damage.

1.1 Charging voltage

The charging voltage measurement reveals whether or not the charging circuit

is working correctly. First warm the engine up. Now put the bike on its stand and

make the battery terminals accessible. Allow the engine to idle. Insert the red

test

cable in the VΩmA jack and the black cable in the COM jack on the

multimeter. Select 20 V DC measuring range. Hold the red test probe against

the positive and the black test probe against the negative battery terminal. Read

off the value

– for a well charged 12 V battery the display should now be

indicating approx. 12.6 volts. Now, depending on the model of bike, increase

the engine speed to around 3000-4000 rpm. With a 12 volt system the reading

should now increase to approx. 13.5 to 15.5 volts; in this case the alternator is

charging correctly. If, on the other hand, the voltage stays the same, then there

is a fault in the charging circuit. If the voltage increases beyond the range 13.5
