At modest voltages (less than 500) the electrons, that are electricity as they move, travel from atom to atom. They are a negative charge. The conductor (metal for simple example) when in the solid state (wire) has atoms that are close enough together that their outer clouds of electrons mingle rather freely. Kind of like musical chairs with 20 chairs and 30 people. The freedom to move makes it easy to push them around with either magnetism, or chemistry. Imagine a hose full of buckshot with water in it. The buck shot is atoms and the water is free electrons. The water can flow through the spaces. When we ad water to one end, water is forced out the other end (near immediately, speed of light). Current is measured in Amps. 6.24X10 to the 18power electrons passing one point in one second is one amp. One volt pushes one amp through one ohm. Jim

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall.

After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
