6 volt boosting question

[phillip d]

We just got the engine on our 2n freed up a few days ago.Hooked up a 6 volt battery that was pretty well charged up and it rolls over fairly slowly mind you but it does roll over.Dad suggested unhooking the live and boosting it with 12 volt directly to the starter but I dissagreed so we left it for now.Is that a safe practice for the starter's sake?I figured if it was double the voltage it was intended for it probbably wouldn't help it any.We used pennetrating fluid in the plug holes and gently rocked it in gear back and forth to get it to let go,should we also let it soak in diesel for abit to help clean it up inside to make it turn over more freely?Is it actually safe to boost it with 12 volt?Thanks pd.

Yes...you can jump with 12 volts. one cable to ground and one cable to the bolt on the starter. Make sure tractor is in neutral. Someone was run over and killed a week ago in Texas. Not cranking fast with a 6 volt battery could be bad connection or the wires are to small..Are the bat cables as big as your thumb? The are 1 gauge I think, fatest cable you can buy....

I had a slow cranker a week or 2 ago and I had to bend a spring a bit to make it push harder on a brush...It could use new brushes!!!

You can do it safely if you follow the advice in tip # 43 at the link below.

Thanks Sean,next time we get to work on it we will boost it with 12 volts,as usuall,Dad was right lol.

Phillip,

Don't put the 12V on the battery but you can jump it out to the starter. It will turn over quickly. Don't do it very long. And make SURE it is in neutral .... as you've read it can be deadly.

My 9N turns over slowly but fires right up .... once I got all the ignition/coil/points/plugs problems worked out. Before that it was very iffy how long it would take to start.

I would suggest looking at the 50 tips article and checking the ignition with a plug and seeing what kind of spark you're making.

Thanks Dave,saved the 50 tips on my favorites,had no spark yet,but still have very old plugs,so have aways to go in that dept. too.

Keep at it, it can be phun. I'm a Dad and am always right (except for that one time -- grin)

change the oil and then put some atf n the cyls.. get new plugs.. after soaking the cyls with atf for a few days and bumping over ow and then expellthe old oil and put new plugs in gapped at .025. points of front mounts are 015, and points on sid emounts are .025.

clean and bright connections on all electricals.. new points.. etc..

I would not attempt to start your 2N engine until I had done several things. I do not know the circumstances but it sounds like the tractor has not been run in a long time and the engine was stuck but now free turning. If that is the case I would drain and replace antifreeze and change the oil with new 30wt and change filter. Prime the engine oil system by using the bolt on the front of the block. Leave ignition key off and jump starter with a 12 volt battery until oil pressure is shown, 5-10 pounds is good enough. Only then would I try to start the engine. If you start it up and run it any amount of time without oil pressure you will kill what could have been a good engine.

I have read on this site often that people have troubles starting with 6 volt system. I put a 9 volt battery in my 9N and have had no troubles ever since. The starter spins the engine noticably faster and it starts better. I did no modifications to the electrical system and have been using it like this for three years now...
