3. With the multimeter set to the diode test function (
ç
), connect the black (–) probe of the multimeter
to the (+) terminal of the diode and the red (+) probe on the other terminal of the diode (Figure 11-35,
Page 11-31). The reading should be approximately 960 mV.
4. Reverse the multimeter probes and note the reading. The multimeter should indicate an overload (no
continuity) (Figure 11-36, Page 11-31). A diode is designed to conduct current in one direction only. If
a diode conducts current (shows continuity) in both directions, the diode has failed and must be
replaced. If a diode does not conduct current (does not show continuity) in either direction, the diode
has failed and must be replaced. See Diode Removal, Section 12, Page 12-14.
5. Reconnect the diode. See Diode Installation, Section 12, Page 12-15. See also following WARNING.
∆ WARNING
• Incorrect wiring could result in severe injury or death.
• Diode and solenoid connections must have correct polarity.
• Keep all persons clear of engine belts when making final connections.
TEST PROCEDURE 11 – STARTER/GENERATOR (GENERATOR FUNCTION)
Read DANGER and WARNING on page 11-1.
NOTE: Perform Test Procedure 10 before proceeding with this test procedure.
Keep the battery connected while performing this test procedure.
1. Place the Forward/Reverse handle in the NEUTRAL position, and chock the wheels.
2. Ensure that the wires are connected correctly and are tight. If they are not, rewire or tighten as neces-
sary.
