Check Power Supply And Ground Circuit

WARNING: This page is about a different car, the 2004 Subaru Outback, 2004 Subaru Legacy, and 2004 Subaru Baja. However, it is still accessible from the selected car via links, so may be relevant.

POWER SUPPLY AND GROUND CIRCUIT CHART

Step	Check	Yes	No
1 CHECK POWER SUPPLY FOR COMBINATION METER. Remove combination meter. < Ref. to REMOVAL . > Disconnect combination meter harness connector. Turn ignition switch to ON. 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. Turn ignition switch to OFF. 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.
