I am looking to replace the regulator (since most everything else was replaced when fixing my battery drain problem). I believe it's supposed to be up near the radiator mount on the driver's side but I am not having much luck. Can anyone enlighten me?

Dan,

You're looking for a metal box that has a large plug on the bottom with 4 wires going into it. It'll be on the driver's side of the radiator. Autozone sells one, Wells VR715,

Sid,

Thanks for the response and I have purchased that same regulator but have not located the old one yet. I can see what looks like the horn relay. Am I looking in the right area? If the alternator has an internal regulator, how would I know? Appreciate the help!

Yes, you are looking in the right area. Sounds like you have may have a internal voltage regulator within your alternator. A alternator with a internal voltage regulator has a different plug (wider with spades laying down - - ). External regulated alternator has parellel spades (=).

71CC,

Just checked and it looks like I have an internal. Well, I'm learning and a picture is worth a thousand words. Thanks for clearing it up for me. Now to return the new regulator . . .

BTW, that is a fine looking 71 you've got! How about I park my Elky at your place and pick it up in a few months? Some folks are just gifted. I'm not one of them . . .
