Engine Starting System & Charging System (Except For HEV): Generator: Inspection: Diode

CAUTION: There is the possibility of damaging the diodes if a mega-tester or a similar measuring instrument is used. Never use a mega tester or equivalent for this test.

1. Check for continuity between the diode lead and terminal E or B. If continuity is not as shown in the table, replace the stator coil assembly.

• At analog type tester

-lead	+lead
E	P1, P2, P3, P4, P5, P6	Yes
B		No
P1, P2, P3, P4, P5, P6	E	No
	B	Yes

• At digital type tester

Tester lead		Continuity
-lead	+lead
E	P1, P2, P3, P4, P5, P6	No
B		Yes
P1, P2, P3, P4, P5, P6	E	Yes
