POWER SUPPLY AND GROUND CIRCUIT SPECIFICATION

Step Check Yes No
1. CHECK POWER SUPPLY FOR COMBINATION METER. 
  1. Remove the combination meter. < Ref. to REMOVAL , Combination Meter. >
  2. Disconnect the combination meter harness connector.
  3. Turn the ignition switch to ON.
  4. Measure the voltage between combination meter connector and chassis ground.

    Connector & terminal 

    (i10) No. 3, No. 4 (+) - Chassis ground (-): 

Is the voltage more than 10 V? Go to step 2.  Check the harness for open or short between the ignition switch and combination meter.
2. CHECK POWER SUPPLY FOR COMBINATION METER. 
Measure the voltage between combination meter connector and chassis ground.
Connector & terminal 
(i10) No. 1, No. 2 (+) - Chassis ground (-): 
Is the voltage more than 10 V? Go to step 3.  Check the harness for open or short between the fuse and combination meter.
3. CHECK GROUND CIRCUIT OF COMBINATION METER. 
  1. Turn the ignition switch to OFF.
  2. Measure the resistance of harness between combination meter connector and chassis ground.

    Connector & terminal 

    (i10) No. 11, No. 12 - Chassis ground: 

Is the resistance less than 10 ohm? Replace the meter case assembly. Repair the wiring harness.
