Alternator for 2006–2011 Honda Civic FA1 14V 90A 7PK

Product Introduction & Features

1. Product Positioning & Fitment Info

2. Core Specifications

• System nominal voltage: 12V, charging output stabilized in the 14V range (13.5–14.5V) to protect the battery and vehicle electronics

• Rated current: 90A, stable output from idle/low speed (1000 rpm and up), supports full load: headlights + A/C + audio + ECU

• Belt type: 7PK, OEM groove profile, eliminates slipping and noise

• Structure: built‑in regulator + internal cooling fan, fully sealed housing, approx. 4.8kg, lightweight and easy to install

3. Key Features

1. OEM‑Level Precise Fit, Efficient Direct Installation

• Mounting holes and electrical connectors are 1:1 replicas; no drilling, rewiring, or adjustment needed, improving repair efficiency by over 50%

• 7PK pulley manufactured to OEM dimensions, high meshing precision, no belt jumping or abnormal noise

• Wiring and pin layout identical to original, preventing wrong connections, blown fuses, or ECU damage

2. 90A High Output, Stable Power Under All Conditions

• High efficiency at low RPM: stable output from 1000 rpm, resolves voltage instability in city traffic and with full A/C in summer

• High‑precision built‑in regulator strictly controls output at 13.5–14.5V, preventing overcharging and undercharging

• Sustained power supply for multiple electrical devices simultaneously, no battery drain at idle

3. Durable Structure for Long Service Life

• Pure copper windings: high‑purity enameled copper wire, high conductivity, low heat, anti‑aging

• Premium wear‑resistant brushes + precision slip rings, service life ≥ 80,000 km under normal conditions

• Fully sealed housing: waterproof, dustproof, oil‑resistant, suitable for high‑temperature, wet, and muddy engine environments

• Upgraded bearings: stable operation at high speed and temperature, no noise or play, reduces maintenance frequency

4. Safety Protection & Quality Assurance

• Built‑in triple protection: over‑voltage, over‑current, over‑heat; automatic current limiting under abnormal conditions to prevent alternator and battery damage

• Manufactured under ISO/TS16949 automotive component standards, tested for endurance, vibration, and water resistance

• Warranty: 12 months / 20,000 km, free replacement for non‑human defects

• Unauthorized disassembly or modification is prohibited; disconnect the negative battery terminal before installation; improper belt tension will shorten life and is not covered by warranty
