Figure 19-9 Diode Test – Probes Reversed
1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in the NEUTRAL position.
Chock the wheels.
2. Disconnect battery and spark plug wire(s). See Disconnecting the Battery-Gasoline Vehicles on page 1-5.
3. Disconnect the 10-gauge red wire and 10-gauge white wire of the diode assembly from the solenoid posts,
located within the electrical component box.
3.1. Remove the cover retaining screw (1) and electrical component box cover (2) (Figure 21-2, Page 21-5) .
3.2. Remove the locknuts (3) from the two large solenoid posts and disconnect the diode wires from the solenoid.
4. With the multimeter set to the diode test function, connect the black (–) probe of the multimeter to the white lead
of the diode and the red (+) probe of the multimeter to the red lead of the diode
(Figure 19-8, Page 19-10) . The
reading should indicate an overload (no continuity). A diode is designed to conduct current in one direction only. If
a diode conducts current (shows continuity) with the meter probes as described, the diode has failed and must
be replaced.
See Charging Diode Removal, Section 21, Page 21-4.
5. Reverse the multimeter probes and note the reading. With the black (–) probe of the multimeter to the red lead of
the diode and the red (+) probe of the multimeter to the white lead, the meter should read approximately 450 mV,
however, a range from 400 to 500 mV is acceptable
(Figure 19-9, Page 19-10) .
6. Connect either the black (–) or red (+) lead of the multimeter to the diode body (case). Connect the other
multimeter lead to both the red and white lead terminals of the diode. The multimeter should indicate an overload,
(no continuity). If continuity reading does occur, it indicates that one or both of the diode leads are grounded to
the diode body (case) and the diode must be replaced.
See Charging Diode Removal, Section 21, Page 21-4.
7. If the diode tests good, reconnect the diode leads. See Charging Diode Installation, Section 21, Page 21-5.
