We are thinking the same thing here but expressing it differently. What I'm saying if the 6V starter on 5V drew 500amps, that's 2,500W. Apply 10V to that same starter, current can double depending on rpms, back emf, load etc. That would be 1000amps X10V for 10,000W. Four times the input power. Of course output power on the pinion to the flywheel will be less than 4X due to magnetic path saturation etc. The problem with 6V systems is getting enough voltage across the coil when cranking. With the battery terminal voltage dropping to 5V while cranking. Then voltage drop on the cables, switches, conenctions and chassis return path. The coil may see only 3V, no wonder the engine won't start. There isn't enough voltage built to jump the gap on a wet plug. Now taking a look at the typical system. A 6V battery from bargain bob's,dusted off from the back of the rack a few years ago.Walmart 4 gauge discount bin cables. Some high resistance cable conenctions becuase everything wasn't truely buffed down to clean metal. A chassis return path through sheet metal istead of bolting directly onto the starter's mounting bolt. Plugs gapped a little wide with some soot on them and wet from being flooded. High resistance automotive plug wires instead of solid core, resistor plugs too. Now try to start a worn out machine on a cold day with summer oil in the crankcase. And old gasoline in the tank. Odds are she isn't going to start.

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
