Outback F4-2.5L (2008)
Connect a test light (rated at approx. 3 watts) in place of the blown fuse and allow current to flow through the circuit. Disconnect one
connector at a time from the circuit. Starting with the one located farthest from the power supply. If the test light goes out when a connector is
disconnected, the wiring between that connector and the next connector (farther from the power supply) is shorted.
2. WITH OHMMETER:
Disconnect all affected connectors, and check continuity between each connector and ground. When the ohmmeter indicates continuity
between a particular connector and a ground, that connector is shorted.
