This new replacement Delco Remy 12V DR44G alternator is for Freightliner MT-45 trucks and Workhorse P4500, W42,W62, and 2-Ton. This Delco Remy alternator contains 12 volts, 145 amps. Additionally, it features an M6 B+ output terminal; R and I connectors and remote sensing.
Delco Remy Heavy Duty Alternators are available with outputs ranging from 160 up to 320 amps for all on-highway truck applications. High efficiency models deliver measurable fuel savings over the life of the vehicle, and alternators equipped with Remote Sense dramatically improves battery charge time.
How do I identify my Delco alternator?
Delco Remy CS130D alternators were used on GM vehicles between 1994-Beyond. Two key identification points of the CS130D alternator is the internal fan and vented case with a serpentine belt pulley and the 4 charge indicator light terminals (all the same size) that appear on the backside of the alternator.
How many amps is a DR44G alternator? – Related Questions
How do I know what amp my GM alternator is?
You should have a stamp on the alternator with a part number and amperage. The part number that starts with F3UZ is the 130 amp, and the F1TZ is the 95 amp. You can use either one.
What size alternator do I have?
The amp rating of the alternator is matched to the vehicle’s electrical system. Older vehicles with fewer accessories may only need a 70- or 80-amp alternator, while a newer vehicle with lots of electronics and accessories may need a 120- to 160-amp alternator.
Where is the alternator number located?
On alternators this number can be found stamped on one of the sides of the front frame or on a tag on the rear cover. On starters it is usually on a plate or tag on the field casing “the main body”.
Where is the serial number on an alternator?
A10: The Serial Number of alternator can be found on its data plate; data plate is usually stuck on the frame of the alternator itself.
What kind of alternator do I have?
If your readings are around 14.4V DC then you most likely have the traditional, non-smart alternator. If your reading is closer to 12.5-13.5V then it’s likely that you have a smart alternator.
What do the letters on the back of an alternator mean?
The most common terminals include: S terminal: Senses battery voltage. IG terminal: Ignition switch that turns the voltage regulator on. L terminal: Closes the circuit to the warning lamp. B terminal: Main alternator output terminal (connected to the battery)
There are three key wires in the loop: a positive wire for the battery, a sensing wire for voltage, and an igniting wire. The ignition input wire is linked to the engine. The energy detection cable monitors voltage and transmits it to the converter, while the energy wire links the alternator and the engine.
How do you self excite an alternator?
Why does an alternator have 3 AC waveforms?
Rotation speed
One full mechanical rotation of the armature creates one full sine wave on a two-pole alternator. If the two-pole alternator spins three complete revolutions in one second, it will create three full sine waves in that one second.
What will happen if you increase the speed of alternator?
As the speed of the alternator increase, it supplies more current to the consumers thus increase performance efficiency.
Why two alternators are connected in parallel?
Alternators are operated in parallel for the following reasons: Several alternators can supply a bigger load than a single alternator. One or more alternators may shut down during the period of light loads. Thus, the remaining alternator operates at near or full load with greater efficiency.
Is alternator output voltage AC or DC?
The output of an alternator is direct current (DC). When the alternator pulley is rotated, alternating current (AC) passes through a magnetic field and an electrical current is generated. This is then converted to DC via the rectifier.
Is 14.8 volts too high for alternator?
A good alternator should maintain battery voltage between 13.9 and 14.8 volts (14.2 is optimum). Even worst-case, with all accessories turned on, there should be at least 13 volts at the battery.
A good alternator should produce about 13.5 to 14.5 volts with the engine idling. If the voltage reading is low (12.5 volts or less), it indicates a charging problem but does not tell you what’s causing it.
