how to check for a good or bad voltage regulator

[shadowgray396]

Whats the date on on the old one, don't toss it. They have value. The last one I saw for a 69 or 70 was around $75

I'm still running my original with no problems.

Or you can have a totally stock looking regulator with the reliability of solid state regulation. A Wells VR715 voltage regulator is totally interchangeable without wiring modifications and accepts the stock Delco cover from the original regulator. Even the mounting holes are in the original location.

Autozone sells the Wells unit under their Duralast brand name and is sold under the same part number - VR715.
