TROUBLESHOOTING AND ELECTRICAL SYSTEM: KAWASAKI POWERED GASOLINE VEHICLES
TEST PROCEDURE 8 – WIRE HARNESS DIODES
See General Warning, Section 1, Page 1-1.
A diode is designed to conduct current in one direction only. Depending on the application, diodes are used
in the vehicle to control electrical system logic, or to help protect relay and switch contacts from excessive arc-
ing. See following NOTE.
NOTE: If a diode conducts current in both directions, the diode has failed closed. If a diode will not conduct
current in either direction, the diode has failed open (Figure 11a-15, Page 11a-18).

The wire harness is equipped with several in-line diodes. The following table describes each diode's function
in the electrical system, the location in the wire harness, and the symptom(s) of a diode failure.
