Features & Benefits
- Brushless advantage: fewer moving parts means less wear and longer life
- Equipped with remote sense which can reduce battery charge time by 50%. Remote sense utilizes a second wire that reads the actual voltage at the battery, signaling the alternator to boost output to compensate for voltage drop, ensuring 14 V at the battery for a full charge between stops
- OE approved, assuring OE quality and performance for aftermarket replacements
- Superior output producing up to 320 A at road speed and 190 A at idle
