KTM 250 SX - Manual (Page 74)

7-7C
Static generator values 250-380 EXC (except 250 USA)
Check the generator output 6 (also see circuit diagram on opposite
page) for voltage between the following cable colors:
– between yellow and brown (ground), connector 7 disconnected
Multimeter display (250): 19 volts +/- 2 volts
(300-380): 15 volts +/- 1 volt
– between white and brown (ground), connector 8 disconnected
Multimeter display (250): 24 volts +/- 2 volts
(300-380): 19 volts +/- 1 volt
– Repeat both measurements with connector 7 and 8 connected. The
measured values should be the same.
NOTE: the black measuring lead of the peak voltage adapter must be
applied to the ground.
Check regulator rectifier output voltage 9 (also see circuit diagram on
opposite page) cable colors yellow/red, regulator rectifier bk connected,
capacitor bl disconnected:
– between yellow/red and brown (ground)
Multimeter display: 14 volts +/- 1 volt
NOTE:
– the black measuring lead S of the peak voltage adapter must be
applied to the ground.
– 300/380 USA corresponds to 300/380 EXC Europe but with less
accessories (blinkers, horn, no capacitor installed). Features no rectifi-
cation, only an over-voltage regulation.
