Connection to the motorcycle
The tester requires a power supply voltage within 9 and 16 Volts D.C.
Make sure voltage never drops below this limit during operation: this situation could occur during engine starting and
idling on motorcycles in which the battery is not in perfect working order. If the tester detects a power supply voltage
lower than 9 Volts, the current procedures will be reset; when the voltage returns to the acceptable tolerance limits the
procedure must start again from the beginning.
The DDS diagnosis instrument (1) may be powered from the motorcycle in any one of the following ways:
- by connecting the instrument power connector (N) to the battery connector (3) part no. 97900.0230 and the latter to
the vehicle battery;
