Malaguti DRAKON125 2022 Workshop Manual page 127

3. Basic parameters
Voltage: DC12V, Current: 1.5A; Sound pressure level: 105dB
4. Possible failures
Contact ablation;
The contact clearance is too large or too small (can be adjusted and repaired);
Coil short circuit or short circuit;
The leading out insert is broken or rusted
5. Horn adjustment
After the horn works for a long time, the contact arm may deform, causing the contact
gap to be too large or too small, making the volume of the horn too small or unable to
make sound. At this time, it can be repaired by adjusting the screw. Now loosen the lock
nut, turn the screw clockwise or anticlockwise, turn on the power supply of the horn at the
same time, adjust until the sound is loudest, and finally lock the nut.
