What are the electrical specifications of the 400-52252R car alternator?

The DB Electrical 400-52252R 12V 130A Remanufactured Alternator provides a 12V output with a 130A amperage rating and a 2.807″ pulley outer diameter. We included this unit in our comparison of remanufactured charging components because it matches several high-volume OEM specifications for Honda and Acura models.

The electrical specifications for this alternator include a clockwise rotation direction and an internal voltage regulator. The 130A rating represents the peak capacity; however, the sustained output under high-load conditions, such as when running the AC and headlights simultaneously, determines if the battery remains charged during heavy use. Because modern vehicles often use smart charging systems, you must confirm if the internal regulator is compatible with your vehicle’s specific PCM/ECU communication to avoid “no-start” codes. This alternator replaces several OEM numbers, including AC Delco 334-2584 and Bosch AL1297N. It serves as the primary component that generates electricity to power your car’s electronics while recharging the battery.

What to Check Before Buying the DB Electrical Alternator

Confirming these specific physical and technical details ensures the unit functions correctly once installed by a qualified technician.

• Verify that the 2.807″ pulley diameter and the specific pulley groove profile match your original factory part to prevent belt slippage.
• Check if your vehicle requires a specific “learning” procedure or battery reset to recognize the new alternator’s resistance values.
• Confirm whether the unit includes the specific mounting brackets and wiring harness connectors required for your vehicle’s chassis.
• Ensure there is sufficient airflow clearance around the housing to prevent the unit from overheating in a tight engine bay.
• Verify that the connector pin configuration matches your vehicle’s wiring harness layout.

Comparing the DB Electrical Alternator to Other Options

This remanufactured alternator sits in the mid-range of the market, offering a balance between cost and OEM-spec performance. Buyers seeking a brand-new production unit with a different warranty tier may prefer a new alternator over a remanufactured one. Additionally, if your vehicle requires a higher amperage threshold than 130A for heavy-duty towing or high-output audio systems, you should look for a higher-capacity unit that meets those specific power demands.
