Dodge Dakota Battery still wont charge

I replaced the alternator, ECU, and battery on my 1997 Dodge Dakota and the battery still fails to charge. I have to charge it every night. The alternator and ECU have both been tested and they work. I think that it could be something to do with wiring but i dont know where to start. i diagram would be helpful.

I was running into this problem with my 97 5.2l Dakota and after some searching I found the the "Fuse Link" between the Alternator and the Battery was blow. Found a suitable "Fuse Link" at a local Auto parts store for about $5.

Where is the ECU Located in a Dodge Dakota


Doubt it's the ECU, but it's behind the passenger kick panel on most Daks. Sounds like bad ground, or something is drawing too much current. Stick a voltmeter across your battery after you charge it, and start pulling fuses until you see which circuit is loading it down, if that is what's happening. Do this with key off. Or instead of pulling your hair out, pay the dealer to diagnose it only, then you repair.

1997 DODGE DAKOTA CHARGING SYSTEM
OPERATION:
The amount of amperage produced by the alternator is controlled by the Electronic Voltage Regulator (EVR) circuitry within the Powertrain Control Module (PCM)
EVR circuitry is connected in series with the alternator field driver terminal and ground. A Battery Temperature Sensor (BTS), located in the battey tray under the battery, is used to sense battery temperature.
Sensed battery temperature and data from monitored line voltage is used by the PCM to adjust the battery charging rate. This is accomplished by cycling the ground path to control the strenght of the alternator magnetic field.
The PCM then compensates and regulates alternator amperage output accordingly.
If a problem is sensed in a monitored circuit, a Diagnostic Trouble Code (DTC) will be stored in PCM memory and the Malfunction Indicator Light (MIL) (commonly refered to as the "check engine light") will be illuminated, providing certain criteria have been met.
DTCs can be read using Chrysler's Diagnostic Readout Box (DRB-III) or a generic scan tool.
When diagnosing any problem concerning the charging system on this vehicle, it is recommended that you begin by scanning the PCM for fault codes in order to eliminate certain possibilities and provide a more accurate and timely diagnosis.
If you have any fault codes pertaining to your charging system, please post them in a reply on this page and I will be happy to guide you through the diagnosis process.

Charging system not working. Major problem with the 1991 Dodge Dakota 5.2L 4x4 Sport charging system not working, major drain on the battery. Searched for short. Any ideas? Already replaced alt. and...


Check output from alternator with a voltmeter it should be between 13.8 to 14.7 if so then check at battery if it is not at least 13.8 minimum to be charging then the big wire on back of alternator is not getting back to the battery through ammeter gauge in dash.
I have hooked a wire from back of alternator straight to the plus[+] side of battery to fix that issue.
Sometimes ammeter gauge burns out breaking the circuit from the alternator back to the battery.

Batterywill take chage and start engine, runs if


you should have both your battery and alternator checked. many parts stores can do this for free while everything is still in vehicle. the battery may have a bad cell and only gives you enough to start once. the alternator may not be producing enough power to charge the battery and run your lights(the flickering). if you cant drive to the parts store some can still test alternator out of vehicle. call and ask

Battery loses charge while driving. Won't


It sounds like you have a major compent shorted out somewhere. Some thing is causing a discharge. Therefore your altenator is not responding and the car is draining the battery. Is the circuit between the altenator and the battery broken?? Also, you may need to check all the chassis grounds. Sometimes all your problems can stem from just a bad ground.
