Check the battery condition as low battery will not induce the alternator to work. Check belt tension and condition. Place a multi meter in the battery to alternator wire and check for dc and ac current and if you have ac then the rectifier diodes in the alternator have failed.

    Follow the wires that burnt and replace the module or relay that they were attached to as this is most likely where your problem is.

SOURCE: 2002 Dodge Ram 1500 ,4.7L V-8 Battery is not CHarging

A lot of Chrysler products have the voltage regulator in the computer. I would check the charging system wiring first for poor connections and if nothing else is found there is nothing else for you to do but change it.

SOURCE: 98' dodge durango not charging. battery is fine

If you are able to drive it to the parts store, they can test the alternator on the vehicle to see if it is charging. If not, check your belts to make sure they are tight and rotating the alternator properly. Last resort, new alternator.

When it won't start, will the engine turn over and try to start, or does it act like a dead battery?

My first point to check would be the fusible link for it. Check the wiring diagram in the shop manual and its location in your year/model/VIN and check it. Suspect it was fried by inadvertently arcing at alternator out put lug when servicing alternator.

Voltage regulator is internal to the Alternator. You have to replace the Alternator.

Hi Les, I;m glad to help. There is an fusible link that runs off the battery cable pull on it and see if it comes apart, if it does replace it and see if everything is working properly. Hope this helps and have an awesome day Les.

ALTERNATOR WON'T CHARGE


Crossed Wires?

How do you know the Alternator is working correctly?

Normally it is the Battery before the Alternator

IF THIS IS THE ORIGINAL BATTERY.. IT is what is the problem

Battery Light still on


The new alternator is probably ok.
I would say you burned a fuseable link in the wiring harness.
The alternator has a fuse wire between it and the battery to protect it from overload.
Have someone check the wires coming out of the back of the alternator. The big wire should have battery voltage, the small wires energize the alternator when you start the engine.

Go to web site WWW.HMASERVICE.COM and register your vehicle by VIN #. You'll then have access to shop manuals, wiring diagrams, technical service bulletins, illustrations, etc.
Provided there is no problem with the vehicle's wiring, find out what the charging current is to the battery. I've seen batteries which TEST good, but when under a CHARGE short out internally.
Example: Tested a battery & charging system on a Hyundai Elantra, the battery tested "Healthy" but indicated there was a CHARGING SYSTEM PROBLEM. I checked the battery voltage while the engine was running and found the battery voltage at 14.3 VDC (which was normal). I then used a Digital DC Clamp meter arount the positive (+) battery cable & found the battery was charging at 70 Amps!.. it was supposidly already fully charged (should have only been taking 4 to 6 amps when fully charged).

Best guess without looking/diagnosing the vehicle myself

Maybe this will help.

on the alternator did you put the little washers where the regulator bolts on back of the alt they must be tight and also the ground cable from the battery to the alt bracket must be tight and grounded sounds like a loose connection
the washers go between the alternator and wires coming out of the harness and the alt also it probalbly goes dead occasionally when you crank it up
