The S series of 6 phase alternators offers incredible low RPM output in a compact and durable package. The 170 amp model is best suited for racing or high RPM applications where good output at idle is required with a low pulley ratio. Highly efficient, these units use less horsepower than conventional 3 phase alternators. 12 diodes, twin rectifier plates and outstanding airflow ensure much better durability than standard 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. NOTE: This "universal fit" alternator will not directly fit ANY vehicle without the installer fabricating their own custom mounting brackets to bolt the alternator to the engine. Be sure to calculate your engine's pulley ratio in order to select the correct diameter pulley for your intended use.
