Ok so the VR706, is that a new style? Thats the type that was on dads cuda when he bought it 4 years ago. I assumed it was old style but I couls be wrong.
My cuda is doa right now I haven't dug into it yet
VR706 is only a modern solid state ( less expensive to build but more reliable is questionable ) way to do the same "one wire" closed field system. It just might increase the running voltage a bit, to 13.2 or so.
