Since 1985, AutoTech Engineering has been producing the highest quality High Output Alternators For Car Audio, Marine, Off Road and Racing Performance and offer MORE vehicle options than any other company. Amperage Ratings We are the only company that utilizes 3 different Test Benches to ensure proper functionality of our units. All units are rated at max output at 1800 car RPM and Idle output of 650 car RPM because few cars idle at 800rpm. Proof in Performance While we do not post EVERY unit online as this would slow down our production and shipping times, we do show various "clamp proof" videos on social media, You Tube and our website. We always publicly show "Proof in Performance" with many output videos with ratings at 650rpm and 1800rpm. PROOF IN PERFORMANCE!!! Load Bank Testers AutoTech Engineering employs the latest in testing equipment using Jimco Carbon Pile testers which allows us to test for: Voltage setpoints Ripple Current Multiple "Rotor" RPM amperage outputs Rotor speed tests up to 6000rpm (2000 car rpm) Stator / Rotor Tester AutoTech Engineering strives to Pre qualify ALL of its Internal Components. We don't simply purchase parts to install into our Alternators. Each part is carefully pre-qualified and Tested to ensure that the it meets or exceeds OUR standards. Rectifier / Diode Tester AutoTech Engineering strives to Pre qualify ALL of its Internal Components and suppliers. We don't simply purchase parts to install into our Alternators without testing them first. Each part is carefully pre-qualified and Tested to ensure that the it meets or exceeds OUR rigorous standards.
