1.CHECK “B” TERMINAL CONNECTION

1. Turn ignition switch OFF.
2. Check if “B” terminal is clean and tight.

Is the inspection result normal?
YES>>GO TO 2.
NO>>Repair “B” terminal connection. Confirm repair by performing complete Starting/Charging system test. Refer to Technical Service Bulletin.
2.CHECK “B” TERMINAL CIRCUIT
Check voltage between alternator “B” terminal and ground.

Terminals | Voltage (Approx.)
(+) | (–)
Alternator “B” terminal | Terminal
E254 | 1 | Ground | Battery voltage

Is the inspection result normal?
YES>>GO TO 3.
NO>>Check harness for open between alternator and fusible link.
3.CHECK “B” TERMINAL CONNECTION (VOLTAGE DROP TEST)

1. Start engine, then engine running at idle and warm.
2. Check voltage between battery positive terminal and alternator “B” terminal.

   Terminals | Voltage (Approx.)
   (+) | (–)
   Alternator “B” terminal | Terminal
   Battery positive terminal | E254 | 1 | Less than 0.2 V

Is the inspection result normal?
YES>>“B” terminal circuit is normal. Refer to Work Flow.
NO>>Check harness between battery and alternator for poor continuity.
