SOURCE: 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.

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.

SOURCE: dodge neon 2002. My alternator is not charging,

wires run direct to alternator from battery ,test big lead for a permanant 12v supplyon the back of the alternator if you have one then the problem is either the brushes worn out or the commutator worn through.or the regulator either way its a recon unit as parts are not sold seperate anymore as not many dealer mechanics know how to repair anything and the spares shops make more profit on a unit than parts so they do not sell spares to stop people like me and you from doing our own repairs

The voltage regulator is mounted on the firewall of this truck. There should be a 2 wire plug that plugs into the alternator, one should be green, ground that wire to see if the alternator starts charging. If the voltage output increases then the regulator is bad.

Alternater wont charge battery and fusable link on starter keeps burning


Bad voltage regulator. Usually built-into alternator.
Start car and unplug battery, if it dies your alternator is dead. Get new alternator. If car keeps running, get a voltmeter and check voltage coming through - should be higher than 12v but less than 18v. Any other number means your voltage regulator is dead, cheaper to get a new alternator.

the amperage of the alternator is immaterial as long as it is big enough to run the electrics of the vehicle
what is indicated here is that the new alternator required an external voltage regulator or a properly operating regulator to regulate the output voltage
battery voltage in a new battery fully charged is 13.2 volts dc and when the voltage regulator is working the controlled voltage is 14.5-14.8 volts dc
check how you wired up the alternator and have an accredited to test the charging circuit

I own a 97 dodge dakota sport v8 magnum with a 318 its having problems holding a charge , i've replaced the alternator the belt and the battery , still won't hold a charge to the alternator


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.

My 1987 dodge dakota is not holding a charge, altonator tested and good battery only a year old but have to push start it to get it to run and my lights are really dim


You need to bypass voltage regulator to be certain alternator is charging properly. When you full field alternator it eliminates voltage regulator. If it indeed is good it will overcharge. If it overcharges as it should when you bypass/full field alternator then the regulator, or its connection or the place it attaches to is rusty & wont conduct a ground.

After changing alternator and voltage regulator. Still not charging. 2nd $15.00 regulator replacment


Check your battery and check the ground wire from battery. Make sure all your wires are clean and good connections. A bad battery will not charge and a dead battery will not charge a alternator maintains a battery not charge a battery, so charge your battery completely before checking that the alternator is working. Check all the wires going to the starter for good tight and clean connections . Hope this helps...

1991 Dodge Dakota 3.9L new altenator but won't stay charged


Double check all connections are clean & tight. You need to get a voltmeter and have the voltage tested at battery with engine off & running. Drive it to the Napa shop you bought the alternator from if necessary, they should perform test free of charge, as the possibility of a faulty one is not out of the question, provided all is connected properly. Did you check that a main fuse for alternator wasn't blown in Uunderhood power distribution box?

Have you actually tested voltage output with multimeter, as this all happens ? May need new alternator to start with, it has voltage regulator built in I believe.
