1995 Ram Charging System Problem

I have a 1995 Dodge Ram 1500, 5.9 L, Auto Transmission,

The problem I seem to be having in the Check Engine Light has been coming on from time to time. The code reads 41, which I know has to do with the voltage being at11.75 or less at the Automatic shutdown. I have cleaned most of the grounds as well as the battery terminals,the relay and the connections going into the underhood fuse box. It will sometimes not throw the CEL for a few days but then other times it will do it everytime I seem to start it up, and the guage seems to be at the low end of normal . I usually wiiggle some of the wires by the fuse box and sometimes I have to jiggle the wire by the alternator and then the light will sometimes go out and the guage will read normal about 14 volts or so.

I checked the Battery to see if it had a full charge and it checked out okay. My question is, Does anyone know why this is doing this, do I need a new alternator or what? My Friend says he thinks it is probably something to do with the ground, but I am at a lsss to know how to correct this

Thank you for your input!!

I believe you answered your question. Check the wiring and connectors that gets the voltage back up when you wiggle them

Turned out to be a bad alternator, thanks for
your help!!

Thanks for the update!
