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

d&v alternator tester

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.
