Electrical - Sxc '99 - KTM 400-660 LC4 1998-2005 Repair Manual

ELECTRICAL – SXC '99
Checking the voltage regulator-rectifier
– Start the engine and switch on the low beam.
– Connect a voltmeter to the two terminals of the capacitor (red/white
cable = positive, brown cable = negative).
– Accelerate the engine to a speed of 5000 r.p.m. and read off the
voltage.
If the reading significantly deviates from the nominal value above,
check the capacitor. If the capacitor is intact, replace the voltage
regulator-rectifier.
Checking the capacitor
– Discharge the capacitor by bridging the two terminals with a
screwdriver and remove.

– Connect the negative pole of a 12V battery with the negative
terminal of the capacitor. The connection between the positive pole
of the battery and the positive terminal of the capacitor (marked +)
is made with a test lamp
– When the power circuit is closed, the test lamp must begin to light
up. As capacitor charging increases, the brightness of the test lamp
must decrease.
– The test lamp must go out after 0,5-2 seconds (depending on the
lamp capacity).
– If the test lamp does not go out or does not light up at all, the
capacitor is faulty.
