If you want it ID'ed, post a pic or two. Some VR's only have two terminals. Let us know if an alternator is used; and if it's external or internally regulated. This could be a legit VR, a gimmick voltage enhancer device or something that fell into the box. If you had the wiring info, it would really help with not guessing.


Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
