Question about 1991 Dodge Ram 350
I have a 1991 Ram 250 with the cummins engine and replaced the alternator and it still won't charge? where do I go next? Is their a regulator on this truck?
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,

Most are on the fire wall. crome with a 5 wire connector with just 3 or 4 wires. check for broken wires ohm them to me sure. had same issue, found broken wire...good luck

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.

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.
