(+)		(–)
Alternator “B” terminal	Terminal
E254	1	Ground	Battery voltage

YES>>GO TO 3.

NO>>Check harness for open between alternator and fusible link.

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

   
   

YES>>“B” terminal circuit is normal. Refer to Work Flow.

NO>>Check harness between battery and alternator for poor continuity.
