Honda Civic charging system wiring diagram for the Honda Civic 2006. This diagram applies to Honda Civic FD also known as Honda Civic Eight Generation or Honda Civic model years 2006-2011.
The main part of the Honda Civic charging system is the alternator. It generates an AC voltage in its field coils that is changed into a DC voltage by a set of rectifier diodes. The DC voltage is then fed to a voltage regulator that is controlled by the ECM/PCM (Engine Control Module/Powertrain Control Module) with the help of the ELD (Electrical Load Detector) unit. The ELD unit senses the amount of current being drained from the battery. The information from the ELD unit is then used by the ECM/PCM to alter the alternator field coil strength. This, in turn, adjusts the output voltage of the alternator to meet the current requirement of the battery and maintain the charging voltage.

Honda Civic Charging System Component Location
Alternator Removal and Installation
Removal
One – Make sure you have the anti-theft code for the radio, or the navigation system, then write down the customer’s audio presets.
Two – Disconnect the negative cable from the battery first, then disconnect the positive cable.
Three – Remove the drive belt. Set a wrench on the drive belt auto-tensioner from above the engine, and slowly turn the wrench in the direction shown, then remove the drive belt. NOTE: This is a hydraulic type auto-tensioner; you must turn the wrench slowly.
Four – Disconnect the alternator connector (A) and BLK wire (B) from the alternator.
Five – Remove the harness connector (C) and harness clamps (D) from the alternator.
Six – Remove the alternator.
Installation
One – Install the alternator.
Two – Connect the alternator connector (A) and BLK wire (B) to the alternator.
Three – Install the harness connector (C) and harness clamp (D) to the alternator.
Four – Install the drive belt. Install the new belt in the reverse order of removal.
Five – Connect the positive cable to the battery first, then connect the negative cable.
Six – Enter the anti-theft code for the radio or navigation system, then enter the customer’s audio presets.
Seven – Set the clock.
