How many amps does a Subaru alternator output?

According to the search results, the amp output of a Subaru alternator can vary depending on the specific model and year. Here are some findings:
– The owner’s manual of a 2016 Subaru Limited states that the stock alternator has a maximum amp output of 130 amps.
– A forum post mentions that the alternator in a 2020 Subaru Outback is indicated to put out 190 amps, but the amp output at idle may vary depending on the load.
– Another forum post suggests that the alternator in a Subaru WRX may have an output of around 65 amps.
– There are aftermarket high-output alternators available for Subaru vehicles, such as a 270 amp alternator for a Subaru Forester.
It’s important to note that these findings are based on user discussions and may not apply to all Subaru models. For accurate and specific information about the amp output of a particular Subaru alternator, it is recommended to consult the owner’s manual or contact a Subaru dealership.

How many amps does a typical car alternator produce?

Alternator ratings range from about 60 or 70 amps up to 150 amps or more on many late-model vehicles. Some high-output alternators can generate upward of 200 amps. The amp rating of the alternator is matched to the vehicle’s electrical system.

How many amps should a good alternator put out?

between 40 to 120 amps
The amperage output of a car alternator can vary depending on the vehicle’s make, model, and electrical requirements. In general, most car alternators have an output rating between 40 to 120 amps. Older vehicles or smaller cars typically have alternators with lower output ratings, around 40 to 70 amps.

Can you put a higher amp alternator on my car?

Most alternators for passenger vehicles are rated between 60 and 200 amps, but you can install aftermarket units that generate up to 400 amps of current.

How do I tell what amp my alternator is?

Look for a diagram under or near your fuse box cover. It will have individual amperage numbers (sometimes along with volts) already set by the manufacturer. Add up those numbers to find what amperage your alternator needs to feed the car’s electrical system. Verify this number with the part manufacturer, if necessary.

What is the output voltage of a Subaru alternator?

During charging (with the alternator at full output), you should see no less than about 13.8 volts across the terminals (+ and ground) of the battery, and no more than about 14.2 volts.

What is the voltage of the alternator in a Subaru Impreza?

If the ECU detects a “no load” situation anywhere between 20 seconds and 1-minute it will pull the “C” terminal (blue wire) to ground which reduces the alternator charge output to around 12.9v from the usual 14.2 to 14.4volts.

How many amps does a Subaru alternator put out?

The Small Case OEM alternator is rated at 80 amps with 50 amps at idle. The supplied alternator makes 170 amps at normal idle. The vehicle needs a maximum of 100 amps to supply existing electrical loads with all accessories on leaving little room for additional accessories.

How many amps is my factory alternator?

The amperage output of a car alternator can vary depending on the vehicle’s make, model, and electrical requirements. In general, most car alternators have an output rating between 40 to 120 amps. Older vehicles or smaller cars typically have alternators with lower output ratings, around 40 to 70 amps.

What gauge wire is a Subaru alternator?

Main Power Cable – This is the large cable that is bolted to the alternator itself. Subaru typically runs 2x 8 AWG (approximately 6 AWG combined) wires that connect up to the fusebox and the battery.

How do I know what output my alternator is?

You do this by connecting a voltmeter across the battery terminals. With the engine running at fast idle, the voltage at the terminals should be 14 volts or slightly higher. If it’s below 13.5 but above 12, the alternator may be weak. If it’s below 12, the alternator is not working at all.
