I just got a K20 plow truck with a diesel 6.2. What does it mean if the red wire on the back of the alternator is putting out 14.7 volts but it isn't reaching the battery?

Also the truck has several other electrical issues in case they are related: Headlights intermittent; temp, oil, and alt gauges not working.

I greatly appreciate any help.
