WIRING DIAGRAM

INSPECTION PROCEDURE

1. INSPECT FUSE (D/C CUT, MPX-B)

1. Remove the D/C CUT and MPX-B fuses from the engine room R/B and J/B No. 1.Measure the resistance.

   Standard resistance:

   Below 1 Ω
   

NG	REPLACE FUSE

OK

2. CHECK COWL SIDE JUNCTION BLOCK RH (POWER SOURCE)

1. Install the D/C CUT and MPX-B fuses to the engine room R/B and J/B No. 1.

2. Disconnect the RK J/B connector.

3. Measure the voltage according to the value(s) in the table below.

   Standard voltage:

   Symbol (Tester Connection)	Specified Condition
   RK-5 - Body ground	10 to 14 V

NG	REPAIR OR REPLACE HARNESS OR CONNECTOR

OK

3. CHECK HARNESS AND CONNECTOR (COWL SIDE J/B RH - BODY GROUND)

1. Disconnect the RD and RA J/B connectors.

2. Measure the resistance according to the value(s) in the table below.

   Standard resistance:

   Symbol (Tester Connection)	Specified Condition
   RD-7 - Body ground	Below 1 Ω
   RA-5 - Body ground

NG	REPAIR OR REPLACE HARNESS OR CONNECTOR

OK
