Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

1. CHECK TERMINAL "1" CONNECTION 
   1. Turn ignition switch OFF.
   2. Verify terminal "1" is clean and tight.

      Is the inspection result normal? 

      YES: GO TO 2.

      NO: Repair terminal "1" connection. Confirm repair by performing complete Charging system test using EXP-800 NI or GR8-1200 NI (if available). Refer to the applicable Instruction Manual for proper testing procedures.

2. CHECK TERMINAL "1" CIRCUIT 

   Check voltage between generator connector E204 terminal 1 and ground.

   (+)		(-)	Voltage
   Connector	Terminal
   E204	1	Ground	Battery voltage

   Is voltage reading as specified? 

   YES: GO TO 3.

   NO: Check harness for open between generator and fusible link.

3. CHECK TERMINAL "1" CONNECTION (VOLTAGE DROP TEST) 
   1. Start engine, then engine running at idle and warm.
   2. Check voltage between battery positive terminal and generator connector E204 terminal 1.

      (+)		(-)	Voltage
      Connector	Terminal
      E204	1	Battery positive terminal	Less than 0.2V

      Is the voltage reading as specified? 

      YES: Terminal "1" circuit is normal. Refer to "WORK FLOW (WITH EXP-800 NI OR GR8-1200 NI) " or "WORK FLOW (WITHOUT EXP-800 NI OR GR8-1200 NI) ".

      NO: Check harness between battery and generator for high resistance.
