Unless there's some overriding reason to stay "original", swapping to a 10-SI internal regulated alternator would be a much better choice. The "Delcotron" alternator with the external regulator that you're running now was a fairly low-capacity unit with chronic diode failure problems and a few other gremlins. The switch to the later design is easy, and it's much more reliable.

Thanks for the reply Hotrod Lincoln. I have the parts to potentially fix it now. I don't use the truck a whole lot, especially at night where I need much battery juice, but if this doesn't work out or fails in short order I will certainly try your suggestion. Do I need to change any wiring to do this? Will my amps gauge potentially work if I do this conversion? Thanks for the reply.
