So, turns out that when you move the battery to the back jump seat area, you need to add a second ground to the frame at the engine. My buddy Charlie figured that out, and once I added that fella on there it was awesome! So, TWO grounds with a jump seat battery. One right there at the battery, and one at the engine. In my case I added one from the lower starter bolt right to the frame by the steering box. Runs awesome. Now, does anyone know how to hook up a Spartan horn?
