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.
The voltage output of the DR44 is adjusted by varying the PWM duty cycle from 5 to 95%. Duty Cycles 0-5% and 95-100% are used for diagnostic purposes. See PWM/Voltage scale below. If the DR44 does not see a PWM signal, it defaults to 13.8V output.
What is the L terminal on a GM alternator?
Terminal L is the control circuit for the GM system. The PCM sends a 5-volt, variable duty cycle signal to the terminal to control the alternator voltage set point.
The AD230 and AD244 were commonly found on the trucks. The AD230 was ~105a and the AD244 was ~130a. They both had the same mounting points, but the 244 was physically bigger than the 230. All these alternators have the oval, 4-pin Metri Pack 150 connector on the built-in regulator.

What vehicles came with ad244 alternator?
The AD-244 alternator fits the 4.8L, 5.3L, 5.7L, 6.0L, 6.2L, 8.1L V-8 and 6.6L Duramax Diesel engines for the Tahoe, Avalanche, Escalade, Yukon, Silverado, Sierra, Denali, and Suburban.
How many amps is a ad244 alternator?
Product description. This Alternator Produces 220 Amps, Which is a Huge Jump Above Stock. It is Perfect for Vehicles With a Lot of Accessories and Equipment and is Used in Tandem With Our Car and Truck Ls Relocation Brackets.
Is it OK to install a higher amp alternator?
That is, your alternator will only supply the amount of amperage a particular component demands—and no more. So high-output alternators will not harm your components or charging system, no matter how high you go with the amps.
Is it better to get a higher amp alternator?
High Output Alternators provide the current you’ll need for LOUD car audio. To avoid the dreaded red light of despair in the suddenly silent night, you will need to upgrade your electrical charging system. High Output Alternators provide amperage that your stock alternator cannot produce.
Will a higher amp alternator charge a battery faster?
Make sure you do not choose your alternator too small. A larger one will ensure that the battery is charged faster and engine hours are kept to a minimum – we suggest choosing an amperage between 30 and 50 % of the battery capacity.
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.
How can I tell the amperage of my alternator?
How do I know how many amps my alternator is?
Look for a diagram under or near your fuse box cover. It will have individual amperage numbers (sometimes along with volts) already set by the manufacturer. Add up those numbers to find what amperage your alternator needs to feed the car’s electrical system. Verify this number with the part manufacturer, if necessary.
How do I check the amperage of my alternator?
Alternator amp output test.
Clamp the ammeter around the positive output wire on the alternator.
Connect the carbon pile to the battery.
Zero out the ammeter (connect as above and perform the test with the vehicle off).
Start the vehicle and hold the engine at around 1,500 rpm.
Does alternator charge at idle?
Do Car Batteries Charge While Idling? A car with an idling engine will still recharge your battery, but at a much lower rate than if you were driving. The reason for this is that modern cars have a lot of additional electronics that use up power.
How many amps is 3000 watts alternator?
To obtain 3000 Watts AC at 120 Volts from an inverter, you must replace your 100 AMP alternator with an expensive 250 AMP alternator and install MULTIPLE heavy duty batteries. In addition, 50 more amps are required to operate your vehicles accessories, lights, flashers etc.
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.
At what rpm does an alternator work best?
Alternator may not generate sufficient charging voltage until alternator speed is greater than about 2000 RPM. Typically, alternators have their full output rated at 6000 RPM but can continue to spin up to 12,000 RPM or more without any additional increase in output.
Does engine rpm affect alternator output?
Alternator output is dependent on a number of factors: battery condition and capacity, wire size, engine horsepower and engine RPM, battery temperature and alternator temperature. Of these factors, alternator speed and temperature are the most important.
