Olliejunkie, 21" battery cables are very long in my book. I am used to the cables on my 8Ns which are approximately 10". An engine in good tune will start reliably cranking at a very low speed. I tried an experiment one cold winter day when one of my Ns did not want to start. I connected the ignition system to a small fully charged 6 volt battery - this battery did not provide any voltage to the starter. The tractor cranked very slow, same as before, but now fired right up. Small battery cables can cause slow cranking speed - that is the part you hear. The same voltage drop that causes the slow cranking speed is also stealing voltage from your ignition. I would maintain for 6 volt systems the no start is more times due to no spark rather than low cranking speed. This is the principle behind gear drive starters; the low cranking speed reduces the load on the battery, thereby, saving voltage for the ignition.

Today's Featured Article - My Ford Golden Jubilee - by Troy Estes. This article is about my '53 Ford Jubilee and a story that starts with taking the tractor to my brother's Starter/Alternator Rebuilding shop for a wiring fix. The generator was shot as well as all the wiring. I dropped off the tractor expecting a transformation from a 6 volt to a 12 volt system utilizing the original generator housing, and a total rewiring of the whole tractor. The front end center pin bushing was worn also so I ask that they replace it if they had time. Well, that’s wha
