WELCOME TO AUTOTECH ENGINEERING
Since 1985, we have 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. If your vehicle application is not listed, give us a call or email us for more assistance. Se Habla Español. Please note that photos on our catalog are for "reference" only showing the OEM the vehicle comes with. We build a Denso Hairpin style Alternator which may appear different, but will fit with added spacers or brackets provided (some washers and bolt may need to be purchased separately). Please read our Technical help instruction sheet for additional information.

High Output Alternators
We are constantly adding New applications to our online catalog . If you cannot find your vehicle does not mean we cannot build one. Contact us at 1-800-345-4952 for a custom quote today. Most "common GM" Units are available in stock, but Custom High Output units are custom built, so an average lead time of One (1-2)Week is required for orders. ALL Alternator orders are Non-Refundable.

Siempre estamos agregando aplicaciones nuevos. Si no encuentran su vehiculo, comunican se con nosotros directo por email, whattsapp o telefono. Muchos de unidades "comon" estan desponible, pero unidades de Alto Amperage "especiales" require una semana para fabricar.
EXCEEDING THE STANDARD
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.
- Multiple Voltage bypass options
- Readily available for AGM
- Lithium Battery options.
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 High Output Alternators and starters come standard with OEM, High Temperature Bearings for long life.
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!!!
Warranty Policy
All units come with our Lifetime Labor and 1 Year Parts, Limited Warranty. Warranty covers any premature bearing or Internal voltage regulator failure. It does not cover failures due to improper installation or burned units.
NOTE: Warranty does not cover "ABUSE" of units and Improper installation. All units are Custom built, so Alternators are NON Refundable. Each unit is tested TWICE before it leaves our facility, ensuring proper amperage and voltage for each order placed. Do your due diligence before ordering. Photos on website are for reference only. We manufacture a Denso hairpin design which may not look like your factory alternator but will fit (some spacers or brackets may be included for proper installation and a shorter belt is required).
TESTING PROCESSES
Computerized Tester
AutoTech Engineering is the ONLY company that employs three (3) different Test machines to ensure that EVERY unit meets our custom specifications. Our Computerized tester is 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, nor cruise at 4000rpm so we test under TRUE Vehicle 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)
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.
