CHECKING THE CONNECTIONS
Check rust and moisture of connectors.
1) Disconnect
• Connectors
2) Dry each terminal with an air blower.
3) Connect and disconnect the connector twice or three
times.
4) Pull the connector to check that it will not come off.
5) If the terminal comes off, bend up pin (A) and reinsert
the terminal into the connector.
6) Connect
• Connectors
NOTE
The connector parts are assembled properly when they
“click”together.
7) Check for continuity with a Tester.
NOTE
• If there is no continuity, clean the terminals.
• Be sure to perform the steps 1 to 7 when checking the
electrical system.
• For a field remedy, use a contact revitalizer.
• Use theTester as shown in figure.

CHECKING THE SWITCHES
ELECTRICAL SYSTEM
• Set theTester selector to “ ”.
• Insert the terminals of the tester in the connector
corresponding to the cables in question.
• Check continuity.
SWITCH CONNECTIONS AS SHOWN
INTHIS MANUAL
This manual contains the connection charts (as shown
left)showingthe switchterminals(e.g.,main switch, brake
switch, lighting switch, etc.)
The left column indicates the different switch positions;
the top line indicates the colours of the conductors con-
nected to the switch terminals.
“” indicates the continuity between terminals; i.e., a
closed circuit at the special switch positions.
In this chart, “BL”and “R”are continuous when the switch
is set to “ON”.

IGNITION SYSTEM
THE IGNITION SYSTEM FAILSTO OPERATE
(NO SPARK OR INTERMITTENT SPARK)
Check
1) Spark plug
2) Spark plug cap resistance
3) ”CDI” control unit resistance
4) Main switch
5) Resistance of condenser charging coil
6) Pick-up resistance
7) Ignition system connections
1 Spark plug
• Check the spark plug conditions
• Check the spark plug type
• Check the electrode gap
Electrode gap:
0,7 mm
Standard spark plug:
NGK BR 9ES
INCORRECT
Faulty spark plug ➜
Replace or adjust the electrode gap
CORRECT
2 Spark plug cap resistance
• Remove the spark plug cap
NOTE
Removing the spark plug ➜ Rotate the cap anti-
clockwise
Installing the spark plug ➜ Turn the key clockwise.
• Connect Tester (k )as follows:
- Terminal (+) Tester ➜side 1
- Terminal (-) Tester ➜side 2
Cap resistance:
5K ± 20% a 20°C
INCORRECT
Faulty spark plug cap ➜ Replace
CORRECT
