12 diodes, twin rectifier plates and outstanding airflow ensure much better durability than standard Delco CS130 based alternators, 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. Because of their compact size and standard GM mounting ears, these alternators also work well in many aftermarket or custom bracket installations.
