Internal Voltage Regulators

All of our Internally regulated Alternators are supplied with Brand New Voltage regulators that meet or exceed OEM specifications. Voltage Set Points are set to OEM unless otherwise noted.

Dual Bridge Heavy Duty Rectifiers

All Denso Style Hairpin Alternators are supplied with Heavy Duty, Dual Bridge Heat sinks along with 12 Press Fit Avalanche diodes.

ALL our 128mm alternators are supplied with 12-50amp Avalanche Diodes for maximum durability.

ALL our 138mm alternators are supplied with 12-50amp or 12-80amp Avalanche Diodes for maximum durability.

Premium Bearings

All our Alternators and starters come standard with OEM, High Temperature Bearings for long life.

Amperage Ratings

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 650 car RPM.

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 continue to publicly show "proof in performance".

Warranty Policy

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.

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)

Rectifier / Diode 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.

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 without testing them first. Each part is carefully pre-qualified and Tested to ensure that the it meets or exceeds OUR standards.
