Amperage Ratings
Proof in Performance
Premium Bearings
We are the only company that utilizes 2 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 600 car RPM.

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 continue to publicly show "proof in performance".
Warranty Policy
Proof in Performance
Proof in Performance
All of our units come equipped with our Lifetime Labor and 1 Year Parts, Limited Warranty. Warranty covers you for any premature bearing or voltage regulator failure. Unit requiring warranty will be analyzed prior to any repairs made for possible suggestions and recommendations to root case of failure. NOTE: Warranty does not cover "ABUSE" of unit. All units are Custom built, so Alternators are NON Refundable. Every unit is tested TWICE before it leaves our facility to ensure proper amperage and voltage for each order placed. Please do your due diligence before ordering.
Testing Processes
Computerized Tester
AutoTech Engineering is the ONLY company that employs two (2) different Test machines to ensure that EVERY unit meets our custom specifications. Our Computerized testers are fully automated which allows us to test for:
- Ripple current
- Voltage setpoints
- Feedback Voltage
- Leakage
- Multiple "Rotor" RPM amperage outputs
- Rotor speed tests up to 6000rpm (2000 car rpm)
AutoTech Engineering tests its units under actual Vehicle RPM speeds, Most vehicles DO NOT Idle at 800rpm, so we test under TRUE Idle conditions.
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)
