Mechman B-Stock alternators are factory-refurbished units that may have been lightly used, returned, or reconditioned. They may show minor cosmetic imperfections like scratches or finish blemishes but are fully tested to meet Mechman’s strict performance and reliability standards. These units deliver the same high-output performance as new alternators at a reduced price.

The S series of 6 phase alternators offers incredible output in a compact and durable package. 12 diodes, (instead of the normal 6 diodes) and twin rectifier plates with outstanding airflow ensure long service life, even in severe conditions. A side output stud and seamless rear cover with a side output plug allow for better clearance from the back of the alternator to the front of the engine and a smooth appearance. 

A single wire on the provided pigtail gets connected to any ignition switched 12V+ source to turn the alternator on and off with the ignition switch. Simply run a properly sized positive and ground cable from the alternator to the terminals of the battery and the alternator will work perfectly, regardless of what kind of wiring harness you have.
