For those who remember my post a few weeks back, and for those who don't, I'm posting the solution to a sudden no-start situation with my '47 H.Rather than repeat all the conditions - I'll just go to the solution and why it was the solution. I replaced the battery cables. I think the positive was the culprit - it was too thin and too old - but I replaced both anyway just to be sure. I'd cleaned the connections and tried again before replacing the cables. I'd heard of situations where too much resistance can build up in old cables but this was the first time I'd experienced it - didn't help things that the cable was too thin as well. To have the tractor go from starting fine to absolutely nothing was a bit of a surprise. I would have expected, with a resistance build-up, a gradual slowing on the starter. Now I've got fat brand new copper cables. I did triple strands of some lawn-tracter battery cable but I think, with that amount of copper, they must be close to 0 guage. I also took the liberty of running the negative cable to a ground on a bare spot on the starter flange - held down by one of the starter mount bolts. So that's it. I went through some other shenanigans before I found this solution but the short story is, if your cables are old or of unknown age, replacing them can be an inexpensive way to avoid one type of a no-start situation. Thanks to all those who posted help.
