POWER SUPPLY AND GROUND CIRCUIT

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

Connector & terminal 
(i12) No. 3 (+) - Chassis ground (-): 
Is the measured value more than 10 V? Go to step 2.  Check harness for open or short between ignition relay and combination meter.
2 CHECK POWER SUPPLY FOR COMBINATION METER. 
Measure voltage between combination meter connector and chassis ground.
Connector & terminal 
(i12) No. 7 (+) - Chassis ground (-): 
Is the measured value more than 10 V? Go to step 3.  Check harness for open or short between fuse and combination meter.
3 CHECK GROUND CIRCUIT OF COMBINATION METER. 
  1. Turn ignition switch to OFF.
  2. Measure resistance of harness between combination meter connector and chassis ground.

Connector & terminal 
(i10) No. 20 (+) - Chassis ground (-): 
Is the measured value less than 10 ohm? Go to step 4.  Repair wiring harness.
4 CHECK GROUND CIRCUIT OF COMBINATION METER. 
Measure resistance of harness between combination meter connector and chassis ground.
Connector & terminal 
(i11) No. 16 (+) - Chassis ground (-): 
Is the measured value less than 10 ohm? Replace combination meter. Repair wiring harness.
