Charging Problem

[jburgessx2]

I bought our 85 PT40 in January and drove it from Missouri to
California. I did quite a bit of night driving and noticed the
headlights would get dimmer and dimmer. I checked the engine volt
meter and it was draining vice charging. I started watching the guage
and noticed it would occasionally start charging and the lights would
brighten. But, it didn't do it often enough. I started the generator
and it immediately started charging and continued to charge.

I'm not sure if I have a voltage regulator issue, loose connection, or
an alternator problem. I wouldn't think it was the alternator because
it would charge occasionally. If it is a voltage regulator problem,
where would it be located and are they easy to buy?

As always, I appreciate the help. I'm narrowing down my list of fixes
and finally starting to feel like I'm getting the upper hand.
