I can't see why it would be a failure. I don't find that it cuts my power down at all. I know it regulates, but it keeps the machine going. I've tried both w/loadmatch and w/o Loadmatch, and it does work, and it works great. Even for transporting my machine on a road with a real steep hill, climbing the hill, machine will bog down without Loadmatch. With Loadmatch on, machine just stomps right up the hill at normal transport speed. I'm glad I have it.
