Honda CSC29 Stator Replacement

소개

The objective of this repair guide is to instruct the reader how to remove and replace the stator in the CSC29 alternator. The stator is a series of copper windings that transfer current generated from the rapidly rotating rotor to the rectifier bridge assembly. This current eventually finds its way back into the car battery.
