MAD ELECTRICAL?

I just tested the alternator on the car with my multimeter set to volts it was bouncing between 15 and 16 volts all the time. Any thoughts? I am going to add to this, both the mechanical and solid state regulators are trying to hold it to 13 to 14 volts, I think this might be where all the pulsating is coming from. I am going to pull the alternator and have it checked at a parts store. Is there anything I should make sure they check? Thanks for putting up with me.
