ELECTRICAL SYSTEM
IGNITION SYSTEM (DR-Z400E)
DESCRIPTION
In the capacitor discharged ignition system, the battery’s electrical energy charges the capacitor. This en-
ergy is released in a single surge at the specified ignition timing point and the current flows through the
primary side of the ignition coil. A high voltage is induced in the secondary windings of the ignition coil,
resulting in a strong spark between the spark plug gap.

• Improper coupler
connection
Measure the battery voltage between input
lead wires (O/W and B/W) at the CDI unit
with the ignition switch in the “ON” position and
the engine stop switch in the “RUN” position.
Incorrect
• Faulty ignition switch
• Faulty engine stop switch
• Broken wire harness or
poor connection of related
circuit couplers
* Make sure the transmission is in the neutral position.
Also, make sure the fuse is not blown and the battery is
fullycharged before diagnosing.
