Does my 2000 villager have a voltage regulator seperate from the alternator?

Yes the regulator can be replaced seperate. It's located on the back of the alternator but was likely replaced if you bought a new alternator. Not to say it's not bad though. If this is a remain unit from a local parts store I would not think twice at this being your issue. I see so many faulty right out of the box. Alex

NAPA - NAPA - NAPA! Power Supreme!

let me guess>Autozone? return it either new or reman and I've seen way to many bad ones right out of the box on both.go to NAPA,they have a VERY VERY low return rate. no comparison to the ZONE,ADV,ORLY.that's why they give you a lifetime warranty because they know that they are going to fail,but they can afford to give you another one,kids building and rebuilding them for pennies somewhere across blue waters!
