Ducati Diavel Service Manual: Testing the battery charging system

Note

The on-screen icons used during this procedure are explained in a table at the end of this section.

You can determine the engine rpm required for generator to produce just enough current to charge battery, feed the injection ignition system and all electric items fitted to motorcycle. When applied to a cable, the clamp-type amperemeter (1) part no. 88765.1126V detects the magnetic field generated by the current passing through that cable.

Warning

The clamp-type amperemeter must not be connected to wires through which electrical current is flowing.

Insert the clamp-type amperemeter into the battery positive terminal lead with the arrow on the clamp pointing towards the battery positive terminal (+).

On the dds diagnosis instrument (2), select the "measurement module" function by pressing the corresponding icon; then press the "ammeter" icon (f) followed by the "start" icon.

If the measured current is a positive quantity, it means that generator is feeding all electric items and charging battery at the same time. If the current has a negative sign, this means that the charging system is not able to power the electrical loads and a significant amount of the current required must be supplied by the battery, which is therefore discharging.

Important

If polarity is reversed when clamping the ammeter onto the cable, the sign of the readings will also be reversed, giving rise to incorrect diagnosis.
