PULLEY INSTRUCTIONS: Use pulley from old alternator if this alternator does not have a pulley or pulley supplied is different from the
one on alternator being replaced. NOTICE! When changing the pulley, keep the alternator shaft in a horizontal position and do not
apply any pressure to end of the shaft. Internal damage may occur if the shaft is pushed back and turned. If there were spacers
when the fan and pulley were removed, make sure all spacers are replaced when installing the fan and pulley on this alternator. Hold the
shaft by placing a hex wrench in the hexagonal hole in the shaft while removing or installing the pulley. Tighten the pulley nut to 95-108
Nm (70-80 lb ft).
BELT TENSIONING INSTRUCTIONS: Improper belt tension can cause premature alternator failure. If the belt must be tightened
manually, place a wood block between the alternator and pry bar, as illustrated below. Pry as close to the center of the unit as possible.
Use a torque wrench to tighten mounting bolts to the proper torque as specified in vehicle or engine manufacturer's specifications for belt
tension and mounting bolts torque. DO NOT OVER TIGHTEN BELT!

RECOMMENDATION FOR DETERMINING APPROPRIATE CABLE SIZE
CHARGING LINE CABLE DROP SHOULD NOT EXCEED 0.5 VOLTS (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.
REMOTE SENSE™ TECHNOLOGY senses the voltage level at the batteries or similar location where battery system voltage can be
read and adjusts alternator output. A direct connection from the alternator's Remote Sense™ terminal to the battery provides improved
system voltage readings and optimizes state of charge. (Go to
Sense™ technology)
TERMINAL DESCRIPTIONS (Alternator will function without connecting the S, I or R terminals):
"POS" Terminal - Output terminal connects to the positive (+) battery terminal.
"R" Terminal - Relay terminal carries half system voltage and may be used for certain types of control relays, charge indicators,
tachometers or similar devices. The current draw should not exceed four (4) amperes. Frequency = RPM/6.67
Notice! Do not install the Remote Sense™ terminal lead to this terminal.
"I" Terminal - The Indicator lamp/ignition terminal carries full system voltage. Current draw should not exceed one (1) ampere. It is
recommended that current is not drawn from this terminal.
Ground Screw – Ground lead ensures alternator is grounded and is strongly recommended for optimum performance.
"S" Remote Sense™ Terminal - Monitors battery system voltage at the battery or a common distribution point.
Do not connect anything but the Remote Sense™ terminal line to this terminal. The "R" Terminal is not the Remote Sense™
Notice!
terminal.

If installing this alternator with Remote Sense™ terminal in a vehicle that does not have a sense line, connect a fused (5 Amp)
insulated wire from the Alternator Voltage Sense terminal to the positive (+) battery terminal or the common distribution point at the
