How Much Amperage Do I Need?
The Amp Rating of your replacement alternator should provide at least as much amperage as your vehicle's factory electronics demand, plus any additional amperage needed to power electrical accessories added to the vehicle. There are several ways to determine your OE Amp Rating:
OE Part - Check the Amp Rating stamped on the OE alternator (or if you see an OE Part Number, look it up on RockAuto.com), or
Fuse Box Diagram - Add together the Amps listed on all the vehicle's Fuse Box Diagrams (under the hood and/or under the dash), or
MultiMeter - Use a MultiMeter to individually measure the amp draw of major factory and aftermarket electronics with the engine off and then total those numbers. The replacement alternator should have an amp output at least 50% greater than that total, or
Window Sticker - If it is still available, check the vehicle's factory window sticker to see if an optional higher output alternator was installed
Tip: Alternators work best when operating between 30%-50% capacity. Upgrading to an alternator with higher Amp output than required may improve fuel economy and extend the life of your battery and replacement alternator.
Not Sure Your Alternator is the Problem?
When the battery goes dead, the condition of the battery and the alternator are two of the first things to check. However, do not assume that if the battery is good then the alternator must be bad and the cause of the problem.
