Each High Quality OEM replacement alternator features zinc plated pulleys and fans, new heavy duty front and rear bearings, hardware and insulators, regulator and high amp welded rectifiers, that meets or exceeds OEM specifications. All the alternators meet the high standards necessary to receive a ISO 9001 : 2000 compliance certificate.
Each Starter goes through the following testing:
Under simulated vehicle conditions to exceed OEM specification.
• test #1
Pre-spin mechanical check of bearings and rotors
• test #2
Rotor energizing voltage and speed
Charge lamp circuit checked
• test #3
Amperage at idle rpm
Stator ripple voltage
• test #4
Full output at rated rpm
Stator ripple voltage
• test #
Secondary regulation test used to protect electrical system from voltage spikes
alternator pulleys:
Vehicle manufacturer's provide many different alternator pulleys on late model vehicles. USA Industries alternators are shipped with the most popular pulley. However it is often necessary for the installer to transfer the pulley from the original alternator prior to installation.
• please observe the following guidelines when transferring pulleys:
Never use a "V"-Belt with a serpentine pulley or a serpentine belt with a "V"-Pulley. This will result in belt failure.
Always torque a newly installed pulley to 75 ft. lbs.
A pneumatic ratchet (air gun) with 90 P.S.I. air supply should be sufficient.
