i think the 5015 has an alternator with an internal voltage regulator.. Not sure there are parts available for rebuild... Might be cheaper to just install a new aftermarket alternator like a DENSO Mini, etc..
Like them all, but love the "B"s.

Take it off and bring it to a local rebuilder to run and load test it. He'll be able to tell you how good it is or how bad.  They can be rebuilt, but sometimes it's better to price out a new unit first as Steve mentioned. The little pint size Denso fits a lot of applications with little mods.
