24SI ™ & 28SI™ ALTERNATOR INSTALLATION INSTRUCTIONS
Note: Instructions for 24SI & 28SI to replace 21SI, 22SI & 24SI alternators are on the www.delcoremy.com web site.
WARNING!!!! ALWAYS USE PROPER EYE PROTECTION WHEN PERFORMING ANY MECHANICAL REPAIRS TO A VEHICLE
- INCLUDING, BUT NOT LIMITED TO, ANY INSTALLATION AND OR REPAIRS TO THE DELCO REMY ® ALTERNATORS. FAILURE
TO USE PROPER EYE PROTECTION CAN LEAD TO SERIOUS AND PERMANENT EYE DAMAGE.
Only perform the mechanical functions that you are properly qualified to perform. Mechanical repairs that are beyond your technical
capabilities should be handled by a professional installation specialist.
DANGER!!! To avoid injury or damage, always disconnect the negative cable at the battery before removing or replacing the alternator.
The alternator output terminal is always live (“hot”). If the battery is not disconnected, a tool accidentally touching this terminal and
ground can quickly get hot enough to burn skin or damage tools and surrounding parts.
NOTICE! Some of these are extremely high output Alternators. Always ensure your application is equipped with the appropriate
size and gauge cable. CHARGING LINE CABLE VOLTAGE DROP SHOULD NOT EXCEED 0.5 VOLTS (12V system), 1.0 Volts
(24V system) (ALTERNATOR OUTPUT [B+] TERMINAL TO BATTERY POSITIVE TERMINAL AT FULL OUTPUT). FOR
OBTAINING ADDITIONAL WIRING INSTALLATION INFORMATION, SEE HEAVY DUTY APPLICATION MANUALS OR
CONTACT A REMY INC. REPRESENTATIVE.
FOLLOW ENGINE OR VEHICLE MANUFACTURER’S INSTRUCTIONS FOR REMOVING THE OLD ALTERNATOR FROM THE
ENGINE AND INSTALLING THE NEW ALTERNATOR.
REMOVAL & INSTALLATION INSTRUCTIONS
 Disconnect the negative (-) cable at the batteries.
 Identify and tag all leads when removing the old alternator and install them on the same terminals of the new alternator.
 Insure all leads are reconnected or contained where they cannot ground.
 Torque all fasteners to values labeled in Figures 1, 2 & 3
 This alternator may have more terminals than the one being replaced had or used. It will charge properly with only the battery and
ground leads connected. Use of the other terminals is optional based on need. See “TERMINAL DESCRIPTIONS”, Pages 2 and 3.
