OK or NG

OK

>> GO TO 2.

NG

>> Repair “L” terminal connection. Confirm repair by performing complete Battery/Starting/Charging

system test.

2. 

CHECK “L” TERMINAL CIRCUIT

1.

Disconnect E207 for KA24DE models or A8 for VG33E and VG33ER models connector from generator.

2.

Apply ground to terminal “L” [E207, (Y/B) for KA24DE models or A8, (Y/B) for VG33E and VG33ER mod-
els] with the ignition switch in the ON position.

OK or NG

OK

>> Replace the generator. Confirm repair by performing complete Battery/Starting/Charging system

test.

NG

>> Check the following.

●

●

Harness for open or short between generator and fusible link

3. 

CHECK “B” TERMINAL CONNECTION QUALITY (VOLTAGE DROP TEST)

Check voltage between generator terminal “B” [E208, (W) for KA24DE models or A6, (W) for VG33E and
VG33ER models] and battery positive terminal using a digital tester.

OK or NG

OK

>> Replace the generator. Confirm repair by performing complete Battery/Starting/Charging system

test.
