I had the triangle- battery to engine, engine to car and car to battery.
I added the braided wire used on ac cars to the back of my engine to the fire wall- ac Cars had this extra braided wire. I was at wits end on why I kept burning up expensive “electronic conversion VRs.” I just know either this made a difference or I finally found a VR that worked right (or as described)
I’m also running a 60amp alternator not a aftermarket high output.
