Testing the alternator on your 1994-1998 Dodge Ram pickup, to see if it has failed (or not), can be done with a simple multimeter.

I'm trying to check and correct my memory voltage and timing on the Asus M4a785TD-V EVO board. It's Crucial Ballistix ram, rated 1.8v and 6-6-6-20 (1333mhz) Firstly, i've got CPUZ and it says it's 1.5v, so i found and set the memory over voltage to 1.80. CPUZ still shows 1.5 - i'm obviously doing something wrong.

How To Check Pc Voltage

In this tutorial, I'll show you how to do it in a step-by-step fashion.

NOTE: Although you could apply the basics of this tutorial to test any alternator.. you do have to check the alternator 120 amp mega-fuse in the power distribution center (located under the hood) and the illustration I'm using only apply to the 1994 to 1998 Dodge Ram pick-ups.

Symptoms Of A Bad Alternator

In a nutshell, your Dodge Ram pick-up's alternator has two very important jobs to do:

  1. Charge the battery, as the engine runs, so that you crank and start your Dodge Ram pick-up the next time you need to.
  2. Provide electrical current to all of the accessories while the engine runs. These accessories include:
    1. Headlights.
    2. Radio.
    3. Wipers.
    4. Blower motor (for A/C or heater).

So, when the alternator fails, you'll notice one or several of the following symptoms:

  1. The charge light (also known as the battery light) will be shining nice and bright on your pick-up's instrument cluster.
  2. Whenever you turn on the headlights (night driving), they glow very dim.
  3. The engine won't crank. It will only crank and start if you jump start your pick-up.
  4. The only way the engine cranks and starts is if you charge the battery.
  5. The engine stalls and won't crank (unless you jump-start it).

TEST 1: Battery Voltage Test With Engine Running

This first test will confirm that the alternator is either not charging the battery or that it is charging it.

What you'll do is measure the battery's voltage with your Dodge Ram pick-up's engine running.

If your multimeter registers 12.5 Volts (or less), then the alternator is not working and thus not charging the battery.

Now, if your multimeter registers 13.5 to 14.7 Volts with the engine running, then the alternator is working and thus charging the battery.

NOTE: You'll need to make sure that the battery has enough of a charge to keep your Dodge Ram pick-up running for at least 5 minutes to do this test. If the battery is completely dead, charge it up enough so that it can crank and start the engine.

These are the test steps:

How To Check Ram Vista

  1. 1

    Crank and start your Dodge pick-up and select Volts DC mode on your multimeter.

  2. Probe the positive battery terminal with the red multimeter test lead.
    Truck truck crack key. With the black multimeter test lead, probe the negative battery terminal on your Dodge pick-up's battery.

  3. 3

    Your multimeter is gonna' register one of two possible readings and they are:
    1.) A steady 13.5 to 14.5 Volts DC.
    2.) Or 12.5 Volts that will decrease the longer the engine stays running.

  4. Put an electrical load on the alternator to further confirm that it's either charging or not charging.
    You can do this by turning on every accessory possible (inside the vehicle). For example: Turn on the A/C or heater on high, turn on the windshield wipers, turn on the headlights, turn on everything and anything that uses electricity inside and outside of the vehicle.

  5. 5

    Your multimeter will show you one of two things (as you turn on all of this stuff):
    1.) The multimeter will register a nice and steady 13.5 to 14.5 Volts DC no matter what gets turned on.
    2.) It will register 12.5 V DC and this voltage will decrease more and more as you turn on stuff inside your Dodge vehicle.

OK, let's interpret your multimeter test results:

CASE 1: Your multimeter registered 13.5 to 14.7 Volts. This test result confirms that your Dodge Ram pick-up's alternator is OK and that it is charging the battery.

If the alternator were fried, the voltage your multimeter would have recorded would have been around 12.5 Volts that would have steadily decreased the longer the engine ran.

Now, if you're having to jump-start the pick-up to get it going, then you probably have a bad battery or a parasitic drain. A parasitic drain is tech-speak for something staying on (usually inside the car, for example: a dome-light) and draining the battery while the engine is off.

CASE 2: Your multimeter registered a voltage that steadily dropped down to 9 Volts. This is a clear indication that your Dodge pick-up's alternator IS NOT charging the battery.

Replacing the alternator at this point usually solves around 90% of the No Charge conditions on any Dodge pick-up around the world. That's right, you could stop testing here and say: ‘The alternator is fried’ and be done but.

I suggest two more easy tests to be absolutely sure it is bad. For the first test of the two, go to: TEST 2: Checking The Continuity Of The Bat (+) Cable.

What Ram Do I Have

How to identify computer ram ddr1 ddr2 ddr3, DDR4 Identifying the Computer RAM (Random Access Memory) like DDR1, DDR2, DDR3, and DDR4 physically is not so hard if you follow the steps.

  1. Distance of Notch
  2. Integrated Chip (IC) type

How To Tell My Ram Speed

DDR1, DDR2, DDR3, DDR4 is the most using RAM currently in the market.

First of all confirm is it DDR1, DDR2, DDR3, or Different DDR’s SDRAM. keep your DDR chip front-facing as given bellow. here look to the notch each DDR notch distance is different from others DDR. It’s mentioned in the picture.

Distance of Notch

Max Ram Voltage

    • Notch Means above cuts Mark on RAM
      • DDR1, DDR2, DDR3 having Single Cut mark on the base of the RAM
    • But you can see the Cut mark (Notch) distance (see below photo)
      • Notch of DDR1 and DDR2 are similar but if you see closely,
        • You can find DDR1 Notch is just above the IC and DDR
        • DDR2 Notch is just far to the IC
      • Notch of DDR3 is different from the other two.
  • Integrated Chip (IC)

    • See the Above Photo
      • DDR3 having small and square type IC.
      • DDR2 is just bigger then DDR3 and smaller the DDR1,
      • In this case, too, DDR1 and DDR2 are just a small difference
        • IC in DDR1 are touched both top and bottom of RAM
        • and IC in DDR2 is just center of the RAM
  • Number of Pins in DDR1, DDR2, DDR3, DDR4

    • DDR1 – 184 Pins
      • DDR2 – 240 Pins
        • DDR3 – 240 Pins
          • DDR4 – 288 Pins
  • Voltage of RAM

    • The voltage of RAM cannot be used for the Physical finding of RAM, but it can be used to place the RAM in the Motherboard Slot. (voltage are written in the RAM Slot of Motherboard)
      • DDR1 Volts – 2.5 v
        • DDR 2 Volts – 1.8 v
          • DDR3 Volts – 1.5 v
            • DDR4 Volts – 1.2v
