Question about 1998 Dodge Dakota
Check all the square fuses 50 amp, 60 amp,etc. If you have an alternator fuse that is blown you will have perfect working alternator, and the car will run fine till the battery goes dead. the battery will not charge and the charge light on the dash will not tell you the battery is not charging. This may be a trick that chrysler learned from Mitsubishi. So check ALL the fuses carefully.

I can provide you with a procedure that is simple to perform to help you isolate the circuit which is causing your battery to drain . I call it "the fuse pull isolation procedure". To explain , by pulling fuses from the fuse box (s) 1 at a time while paying attention to a test light bulb hooked into the battery circuit you can isolate the circuit that is causing the drain .
You'll need a 12 volt test light, the kind that has a regular light bulb in it . A digital test light will not work . Before you continue , you will have to locate your dome light / courtesy light fuse and pull it out of the fuse block if your interior fuse box is located inside the truck. The reason being is you'll have the door open to access the fuse box inside the car and it will cause the dome light circuit to be active so it must be eliminated by pulling the fuse. Now, follow these steps :
1.Disconnect your negative battery cable from the battery.
2.Connect the test light between the battery cable end and the neagtive battery post. (You are using the test light to complete the circuit.) Once connected , the test light bulb should light up.
(Note: If it does not light up , then the problem is in the dome light circuit and you will have isolated the circuit . However , if the test light bulb lights up then continue on to step three .
3. Using a fuse puller, pull out each fuse, 1 at a time and then replace it while looking at the test light bulb. When you pull the fuse that causes the light bulb to go out , you have located the circuit that is causing your problem .
Now , you'll have to use your repair book or whatever resources you have available to find out everything that is on that particular fuse circuit which will aid you in locating the component (s) that is causing the battery drain .

Hi, first, have your battery checked as they can go bad this way. There are many possible problems to diagnose in wiring. Go to Autozone or Oreillys for a free scan and ask for the charging system test. It is possible for an Alternator to ground out and discharge the Battery.
The main switch inside your vehicle is the Ignition switch. If it is worn out it may not shut off the silent connections like the spark to your computer or any electric component that goes on when you turn the key.
When these main items are eliminated you are left with wiring. To test the wiring you use an Ohmmeter and disconnect both battery cables from the battery. You attach the Ohmmeter to the two loose battery cables. The reading you get is called a circuit.
When you turn off your car, there should be no circuits with the exception of the Antitheft. When you use an Ohmmeter with a scale it is easier to see a change in the circuit. One by one remove and reinstall the fuses on the fuse panel. Usually the fuse that causes the biggest drop is the culprit.
On a clients 1988 Taurus, he had a bad wire in the wiring loom on the Drivers side. This limited the problem to controls in the door. The Power windows for all 4 doors, the locks, the Keyless entry Pad, the Drivers power mirror were all in that door. In that case, he was getting a Shock touching the car.
Electric problems are challenging.
