Charging system inspections
Battery (TE-TXC)
Remove the saddle (as described in the relevant paragraph) to gain access to
the battery (1).
Disconnect the BLACK negative cable from the battery.
Measure current across the negative terminal of the battery and the negative
cable using an ammeter clamp. A reading greater than 1 mA indicates current
draw by some utility.
If the vehicle is to remain unused for long periods, it is recom-
mended to disconnect the battery from the electrical system and
store it in a dry place.
Regulated voltage (TE-TXC)
Remove the saddle (as described in the relevant paragraph) to gain access to
the battery.
With the engine warmed up and running at slightly above 3000 rpm, measure
voltage across the positive and negative terminal of the battery using a meter
(the battery must be charged when performing this test). If reading is outside a
12.5-14.5 V range, check generator and voltage regulator/rectifier as described
in the relevant paragraph.
Voltage regulator check (TE-TXC)
With the ignition on and the battery charged (12.5-13 V), start the engine: if bat-
tery voltage fails to rise (14 V) within the next two minutes, change the regulator
(1) as outlined in the relevant paragraph.
Voltage regulator check (TC)
Start the motorcycle and using a tester make sure the voltage of the red and
brown cables is 14.5 ± 0.5 V at 5000 rpm; if the voltage is incorrect, replace the
regulator (1).
Voltage regulator
The voltage regulator (1) incorporates the diodes used to rectify the generator
current output.
It also incorporates an electronic device that adjusts charging voltage to battery
charge: if battery charge is low, charging voltage will be lower.
Do not disconnect the battery cables while the engine is running,
or the regulator will suffer irreparable damage.
