Alternator Installation Steps (Alternator For Denso)




● Physically compare the new alternator to the original. Compare the housing and pulley offsets, pulley size and type, pivot and adjustment hole locations, wire connector locations and terminal configurations with the original alternator.
● Install the mounting bracket(s) but do not completely tighten the bolts yet.
● Support the alternator and fasten it into position but do not completely tighten the bolts yet.
● Install the drive belt. If the drive belt is worn, stretched, cracked, oily or glazed, it should be replaced.
● Set the belt tension while tightening the mounting and adjusting bolts. Be sure to set the belt tension and torque the mounting bolts to the vehicle manufacturer’s recommended specifications.
● CAUTION: Do not pry or hit the alternator housing to adjust the belt tension.
● Check the drive belt alignment between the alternator pulley and other drive pulleys. Ensure there is no interference between the drive belt and other components.
● Reconnect the wire connector to its proper location on the alternator. Ensure there is no interference between the wire harness and other components.
● Reinspect all components. Ensure that threaded fasteners are properly torqued and there is no interference between components.
● Reconnect the battery negative cable.
● Start the engine. Let it for 5 minutes to accustom the drive belt. Re-adjust the drive belt using the ‘used’ tension specification.
● Turn the engine off and re-inspect again.
● Re-test the charging system to verify that it is performing according to the vehicle manufacturer’s specifications.
● Identify each wire connection and note the location of each on the alternator.
● Disconnect the wires from the alternator.
● Loosen the alternator pivot bolt but do not remove the bolt yet.
● Loosen the tension assembly’s lock nut or bolt and turn the adjustment bolt so that drive belt tension is reduced far enough to allow belt removal. Some vehicles may be equipped with an automatic, spring-loaded tensioner. Rotate the spring-loaded tensioner using the appropriate tool far enough to allow drive belt removal.
● Remove the drive belt from the alternator.
● Support the alternator and remove the bolts holding the alternator in place. Set the bolts and alternator aside. Be sure to note bracket orientation and fastener length/location before removing the alternator.
● Inspect the condition of the wiring and connectors. Inspect for worn wire ends, continuity, loose or broken connectors, corrosion and pliability. Repair or replace as necessary.

Precautions for Using Alternator For Denso
To prevent damage to the alternator and regulator, the following precautionary measures must be taken when working with the electrical system.
If the battery is removed for any reason, make sure it is reconnected with the correct polarity. Reversing the battery connections may result in damage to the one-way rectifiers.
When utilizing a booster battery as a starting aid, always connect the positive to positive terminals and the negative terminal from the booster battery to a good engine ground on the vehicle being started.
Never use a fast charger as a booster to start vehicles.
Disconnect the battery cables when charging the battery with a fast charger.
Never attempt to polarize the alternator.
Do not use test lights of more than 12V when checking diode continuity.
Do not short across or ground any of the alternator terminals.
The polarity of the battery, alternator and regulator must be matched and considered before making any electrical connections within the system.
Never separate the alternator on an open circuit. Make sure all connections within the circuit are clean and tight.
Disconnect the battery ground terminal when performing any service on electrical components.
Disconnect the battery if arc welding is to be done on the vehicle.
