2005 Subaru Outback 2.5 Alternator Amperage Specs
2005 Subaru Outback 2.5 Alternator Amperage Specs with application table, generation boundaries, verification steps, cautions and official manufacturer lookup.
The 2005 naturally aspirated Outback 2.5L service table specifies a Mitsubishi Electric A003TG2391ZC alternator rated at 12 volts and 110 amps.
The 2005 naturally aspirated Outback 2.5L service table specifies a Mitsubishi Electric A003TG2391ZC alternator rated at 12 volts and 110 amps.
These values apply to the cited 2005 Outback 2.5L SOHC non-turbo application. Turbo, 3.0L, later smart-charging systems and different option packages require their own alternator part and test row.

Subaru Outback Alternator Amperage Specs
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Rated output | 110 A | 12-V generator |
| Generator model | A003TG2391ZC | Mitsubishi Electric |
| Minimum test output | 50 / 91 / 105 A | At 1,500 / 2,500 / 5,000 rpm |
| Regulated voltage | 14.1–14.8 V | At 20°C / 68°F |
The factory table also gives minimum controlled-test output of 50 A at 1,500 rpm, 91 A at 2,500 rpm and 105 A at 5,000 rpm, plus 14.1–14.8 V regulated voltage at 20°C. Those bench-style points are not a command to rev an installed engine to 5,000 rpm for a driveway test.
Rated output versus the factory test points
The Mitsubishi A003TG2391ZC is rated at 110 A, but diagnosis is not based on seeing 110 A at idle. Subaru's controlled minimum-output points rise with test speed: 50 A at 1,500 rpm, 91 A at 2,500 rpm and 105 A at 5,000 rpm. Temperature, load, battery state and test setup are part of a valid comparison.
The published regulated-voltage range is 14.1–14.8 V at 20°C. Charging voltage changes with conditions, so one dashboard reading does not prove alternator failure. Use the factory test method and safe equipment; the high-speed table value is not an instruction for an under-hood free-rev test.
Confirm the circuit before replacing the alternator
Test battery condition first, then inspect belt tension and pulley condition. Measure voltage drop across the positive cable and ground path under load, and check terminals, fusible links and connectors. Resistance elsewhere can reduce delivered current even when the generator itself is capable.
For replacement, match the Subaru/Mitsubishi part assignment, mounting ears, pulley, connector and regulator behavior—not only the advertised amp rating. A physically similar high-output unit can create belt, wiring or control problems. After installation, verify belt tracking, charging voltage and loaded operation without leaving tools near the rotating drive.
Application boundaries for 2005 Outback 2.5L
These values apply to the cited 2005 Outback 2.5L SOHC non-turbo application. Turbo, 3.0L, later smart-charging systems and different option packages require their own alternator part and test row.
The factory table also gives minimum controlled-test output of 50 A at 1,500 rpm, 91 A at 2,500 rpm and 105 A at 5,000 rpm, plus 14.1–14.8 V regulated voltage at 20°C. Those bench-style points are not a command to rev an installed engine to 5,000 rpm for a driveway test.
Subaru 2005 Outback 2.5L specifications can change by model year, engine, platform, wheel, and installed component. Confirm the VIN or engine identity, part numbers, fastener condition, and the current manufacturer instructions before service.
Procedures used with this specification
These steps are the same for every vehicle in this family, so they are documented once rather than repeated on each page. The values above remain specific to this Subaru 2005 Outback 2.5L.
2005 Subaru Outback 2.5 Alternator Amperage Specs FAQs
How many amps is the 2005 Subaru Outback 2.5 alternator?+
The cited non-turbo 2.5L table rates Mitsubishi model A003TG2391ZC at 110 amps.
What voltage should the factory alternator regulate at?+
Subaru lists 14.1–14.8 V at 20°C (68°F) under the specified test conditions.
Should a 110-amp alternator produce 110 amps at idle?+
No. Output follows load and speed; Subaru's minimum controlled-test point is 50 A at 1,500 rpm.
Can any higher-amp Outback alternator be installed?+
No. Match the exact part assignment, mounts, pulley, connector and regulator/control characteristics.
