These trucks do have a regulator. But most importantly check all of your grounds. One bad ground can mess up an entire electrical system. Especially the charge.

Reulater is built in the alt,first you need to check you pos cable going to your alt it should have current at all times,if it does not have current trace that wire back and find out why some will go to the starter,I have had 3 new alt bad off the shelf before but its very rare,

SOURCE: Charging problem on 1996 Dodge Ram 3500 Cummins Turbo Diesel

I had the same problem on a 94 dodge with the cummins. It seems the crank sensor that reads from a notch on the harmonic balancer was the problem Without this sensor reading that the engine is running the alternator wont charge. Possibly the same problem with yours

that code can mean s few things, mine was the camshaft sensor, replaced it for about 50 bucks (part) all better. It is a huge pain to get to though.

SOURCE: my 1992 dodge ram power 250 cummins turbo diesel wont charge replaced alt and battery and still wont charge what can be my problem?

My 1992 Cummins W250 auto trans turned out to be the Computer/ECM mounted on front fender by battery tray. Mine only acted up in cold wheather. It started out with the ASD (auto shut down relay) clicking rapidly. In addition the water in fuel, wait to start and check engine light also blinked fast. In this state, the battery would not charge.

I have replaced the battery and alternator on my 1991 Dodge ram 150 pick up and the motor still dies on its own when running and the battery loses its charge. What could be the problem?


If the battery is dying or losing it's charge when the engine is running then the alternator or wiring is defective so it's not charging the battery.

How do you replace an alternater in a 1997 dodge ram 150 truck


Hi,

You will be needigng the below;

  • New alternator
  • Socket wrench set
  • Torque wrench

  • Determine which alternator your Dodge Ram will need. You'll want to be sure the new alternator is compatible with your Ram's engine. A Dodge Ram made after 2001 may be equipped with a 3.7 L, 4.7 L, 5.7 L Hemi V8, 5.9 L Magnum V8, 5.9 L Cummins diesel, 6.7 L Cummins diesel, 8.0 L Magnum or 8.3 L Viper engine.

    Disconnect the negative battery cable with a socket wrench. Remove the accessory drive belt and disconnect the wiring harness from the alternator. You will also need to remove the support bracket with a socket wrench for 3.7 L, 4.7 L and 5.7 L engines.

    Take the mounting bolts off of the alternator with a socket wrench and remove the alternator assembly.

    Install the new alternator assembly. If you have a 3.7 L engine, tighten the horizontal bolts to 42 foot pounds and the vertical bolt to 29 foot pounds with a torque wrench. Torque the long horizontal bolt and vertical bolt to 41 foot pounds and the short horizontal bolt to 55 foot pounds for a 4.7 L engine. Torque the mounting bolts to 30 foot pounds for all other engines.

    Connect the wiring harness to the alternator, install the accessory drive belt and connect the negative battery cable.

    I hope this helps.

    Good luck.
