The Delco Remy 40SI™ 12V 275A Pad Mount Brushless Alternator keeps you Ready for the Road Ahead™, being equipped with Remote Sense technology, which uses a second wire that interprets actual voltage from the battery and increases voltage output to ensure a constant 14 volts at the battery. Thus, your battery is brought to a fully charged state in half the time. This heavy duty alternator raises the bar with high amp output. The Delco Remy heavy duty 40SI™ alternator features a brushless design with fewer moving parts and internal connections, resulting in consistently better performance, contamination prevention, and extended service life compared to traditional brush-type alternators.
