bn will not start

I don"t know what is wrong. I started my bn wed. It was fine. I went out this morning to start it and at first I heard a bang. Then the second I tried I heard a bang but it still started. I let it run for about 10 min. then shut it off. I tried to start it right away after I turned it off and it will not even turn over. It did drop to 25 last night and it is in a unheated barn. I am charging the battery right know and I hope that that is all it need. Has anyone had this problem or am I the only lucky one to have this issue?

Thanks
Todd
 
Bet if you pull the starter off you will find your bang. You may have a broken starter end case and that would do just that. Seen it more then once and the bang to me says look at that area
 
The end case. Is that the cast iron (i Thing) in the starter or the part of the starter that i think is called the bendix. Sorry for the spelling. It that is the case why did it start and now nothing. Thanks for your help

Well it may have been engaged but when it started the end part which maybe broke has now moved so the starter can not long work at all. Seen it happen more then once and it is not good if it does happen. Only way to be sure is pull the starter out which is a simple 2 bolt thing
 
Not sure what causes them to brake but have seen more then one. Also common for them to hang up in the ring gear but that most of the time locks them up but can also act like what your is doing. Can you turn it over by hand?? If you can not then pull the starter and if it is ok put it back on and try it you may find it will then start if the starter has not broken
 
Ok I will try that. If the stater is bad while I am waiting on it to be fixed can I pull the starter off the Farmall a and use it even thought it is now a 12 volt system?
 
I'm sure you would have noticed this, but...

I had this happen once when blading snow with an 8N. One whole side of the 6-volt battery had blown clean off. That'll ruin a pant leg in short order.
 
Depends on if that starter has been rebuilt for 12 volts or if it is still a true 6 volt starter being used in a 12 volt system. A true 6 volt starter will work just fine on both 6 or 12 volts but a true 12 volt starter will not work on 6 volts. That said there is probably few if any true 12 volt starters made for an A/B/BN but one never knows what some one has done. Either way you can try it and if it spins over then it is a 6 volt one if it does not or spins super slow it is a 12 volt one and will not work on 6 volts
 
A 12v starter is not a 6v it has been wired to use 12v thats why they are called 12v starters. Just look at rebuilstarter listings in a parts book
 
I mean when you convert a 6v system to 12v you dont have to convert the starter. All of our As and Bs are 12v and we never did anything with the starter. Seen 1000s of 12 conversions and the starter was never touched and it works just fine.
 
(quoted from post at 11:04:49 11/26/10) would the cold weather have a factor in it. What would cause it to break then?

63+ years of wear and tear are a factor...

If cold weather were a factor, NONE of these tractors would be around.
