Low cranking voltage at the coil can cause this difficulty. Low coil voltage at startup can be caused by several things. A battery that drops voltage when subjected to starter motor load. Voltage across the battery terminal studs while cranking should stay above 5 volts. If lower, there will not be enough to fire the plugs. Voltage can also be lost in a failing battery terminal connections, or small battery cables. Cable size should be 1-O (big as a 1st grade pencil) copper wire. 6 volt systems require 2X the amps that 12v does. Internally corroded wires are also a source of voltage loss. This can be invisible, and found by feeling the cables after cranking for heat all along them. Failing ignition switch connections, or the switch contacts can lower coil voltage as well. To check this jump from the non-grounded battery terminal directly to the switch side of the coil and give it a start. if it fires easily, the switch, connections, or wires could be suspect. Good luck with a repair, and let us know what you find. Jim

Today's Featured Article - Uncle Cecil's Super A Lives Again - by Mike Purcell.

Some of my fondest memories of these visits are those of learning to drive a tractor at the helm of Uncle Cecil�s 1948 Farmall Super A. Uncle Cecil was the second owner of this wonderful little tractor, but it was almost as though he had adopted an infant. The original owner was a man from Minnesota who bought her from a local dea
