Description
“B” terminal circuit supplies power to charge the battery and to operate the vehicles electrical system.
Diagnosis procedure
Regarding wiring diagram information. Refer to chg-9, "wiring diagram".
1.Check “b” terminal connection
Is the inspection result normal? Yes >> go to 2.
No >> repair terminal “b” connection. Confirm repair by performing complete charging system test using the exp-800 ni or gr8-1200 ni (if available). Refer to applicable instruction manual for proper testing procedures.
2.Check “b” terminal circuit
Check voltage between generator “b” terminal and ground.
Is the inspection result normal? Yes >> go to 3.
No >> check harness for open between generator and fusible link.
3.Check “b” terminal connection (voltage drop test)
Is the inspection result normal? YES >> “B” terminal circuit is normal. Refer to CHG-14, "Work Flow (With EXP-800 NI or GR8-1200 NI)" or CHG-17, "Work Flow (Without EXP-800 NI or GR8-1200 NI)".
NO >> Check harness between battery and generator for continuity.
