Check the small wire going to the alternator to see if it has 12 volts on it when the engine is running.

that wire has a fusible link on it right and it goes to battery positve

Re: electrical question
 

The alternator should be putting out around 14 volts, with the engine running connect your meter to the battery terminals, red on positive black on negative, it should be between 13.8 & 14.2
