AutoTech Engineering Alternators require a .5 inch smaller belt than your OEM Alternator
AutoTech Engineering alternators need a minimum of 650rpm to charge.
Large Case Alternators
220amps at 650 rpms
Full amps at 1800rpms
Unless otherwise quoted or instructed, our units come with the OEM voltage output for plug-and-play alternators. The quoted voltage settings are already built into the alternator's voltage regulator. Remember that in PCM- and ECU-controlled vehicles, the vehicle's “brain/computer” controls the voltage.
Boosted Harness Option
A boosted harness option is available at an additional cost. If you select this option, your harness will arrive with the diode already installed. You can choose 15.3, 15.5, or 15.7 volts.
What is a Bypass?
If you choose to have a bypass, you are wiring around the PCM or ECU voltage control. This allows us to customize the charging voltage beyond what the vehicle’s computer normally permits. In most cases, the battery warning light will remain illuminated.
Bypass charging voltage: 14.8V.
Important: A PCM/ECU bypass is required when using the boosted harness.
