Well, since the run is long, voltage drop is a question. What size gauge
cable you using?

In the mean time I would clamp a jumper cable from the NEG. battery post
to some good clean metal in the back and be sure the CASE of the Alt has
a good connection to the frame up front.

Sounds like the voltage reg. in the Alt isn't up to snuff, that it might
have been strained and is going out.

10v will get you home (without using the lights) but during the day you
should undo the battery from one post, and hopefully recharge it a bit
(trickle, not fast).

hth,
