  • 9n won't start think its the starter hi current switch
  • farmer Dan here yet again with the gruesome twosome 8n & 9n The 9n just clicks now even tho the bat has just been charged and shows full charge with bat tester . I am suspecting the hi current switch and will try to bypass that and see if that is the problem .I has a two month old starter and every wire on the rig has been replaced with the correct wire gauge also brand new heavy gauge bat cables .

  • Re: 9n won't start think its the starter hi current switch
  • OK, so we're talking your 9N, right? Is it the original 6-volt/positive ground system or a 12 volt job, meaning, a 12-volt battery and 1-wire alternator? Electronic Ignition added? FWIW, all 9N and 2N tractor starters never had a solenoid. That's the round can that sets on top of the starter like your 8N. Now, define "hi current switch". If you mean the starter solenoid, then it has been swapped out with a later 8N style and a bit more surgery done to the wiring. If you are trying to describe the Safety Neutral Starter Button on top of the case next to the shifter arm, then that's a different animal. A clicking starter is a typical sign the battery is dead. How did you verify the battery? Just by checking with a VOLT/OHM Meter isn't a true test. The battery needs to be checked on a proper tester, usually only found at auto repair and starter/alternator shops. The tester will check it UNDER LOAD to verify it will take and sustain a charge. You need AMPS to crank your engine, not VOLTS. Think of it this way: Take a 6-volt dry cell battery or 4 D batteries, or 4 AA batteries, or, anyway they all equal 6 volts but have very low amperage. You couldn't start your tractor on a setup like that. Here's a LINK to JMOR's Wiring Pictograms from our HOW-TO's forum. Scroll down til you find yours. If you don't see it, yours ain't right because he has every conceivable CORRECT wiring configuration possible, whether 6 volt or 12 volt or EI. Download a copy for your shop and after applying a better problem solving method, report back here...

  • Re: 9n won't start think its the starter hi current switch
  • Yes 9n ...6 volt one wire generator brand new .pos ground .orig system no electronic ign. No selinoid was calling the starter switch a selinoid erroneously
    Hi current switch equals starter switch you push in on steering box. I for one charged the battery over nite and the bulb battery acid tester showed good side of the green all 3 cells. Wireing all replaced in the origional style with correct gauge .It was all working fine for several months . I don't drive it very much because it has the grease leak problem and the bad noisey transmission . but the motor always starts rite up and just puerrs sweetly / since i rebuilt an old orig carb. I guess if the nuteral starter button switch tests good I will just replace that brand new battery with the one in the 8n and see if that makes it start . then assume the new battery was bad . The first bimart bat i got had a bad cell rite out of the store .So they are probably not great batteries.

  • Re: 9n won't start think its the starter hi current switch
  • Woah, wait a minute here. A 6-volt one wire generator? I thought we were talking about the starter. Yes, the early 9N-10000 B & C generators would only have one wire, ditto for the 2N-10000 generator, but the issue was the starter I thought. The generator is part of the charging system and not related to the starting system -two different animals. Don't be guessing. Start with basics battery first, wiring second, key switch. Get the battery verified at your trusty starter/alternator shop guy -he can check usually for free. A specific gravity check is good -a hydrometer most people never use. How do you plan on testing the safety neutral starter switch? Like stated, you can arc start the switch with a screwdriver. Key switch ON, touch terminal on switch and ground to tractor body.

  • Re: 9n won't start think its the starter hi current switch
  • we have been chatting about everything conceival about why it won't start . If the gen is not working the starter will also not work if bat bad .It won't crank key switch or not on or off .Yes plan on grounding the hi current switch (s N s s )That is what i think it may be .All wires on tractor new gen bat starter cables all new
    Only thing in the loop old is the snss .

  • Re: 9n won't start think its the starter hi current switch
  • Again Dan, the generator is part of the charging system, the starter is part of the ignition system -two different animals and the genny isn't part of the equation until engine is running. It has nothing to do/no effect whatsoever on starting the tractor engine. If the battery is good, go over ALL the wiring again -something must be shorted to ground. If you have lights, cigar lighter, radio or 8-track player, disconnect them. New does not always guarantee good out the door. I was working on a friends Massey-Ferguson last week and found his battery was junk even though he insisted it was good based on "...I just bought it last year...it has to be good...". Yep, new last year from Auto Zone. Didn't check it out the door. Cells were low on water, winter came and battery froze -you can tell by the swollen case. Bad cells mean won't charge. I was able to take it back and get a new one as the 1-year warranty was about to expire by about a week. You don't need the original receipt, just the phone number of the one who purchased it. I also just had similar problem with my daughters 2002 car she just bought. The battery was an O'Reilly's special and purchased new in 2016. They wouldn't take it back...so, lessons learned...

  • Re: 9n won't start think its the starter hi current switch
  • Yes i know the new gen is not part of the immediate Problem . The first bat i got from bimart one year warenty no matter what full money back or replacement . It had one low cell from new . Took it back and this is the next one it always showed good cells and started it fine .No lites radio or lighters . Just total stock wireing with new wire correct gauge. Will be heading back to farm today and will check the switch Hi current one . I suspect it is the problem . Again bat been in two months . That switch is the only unit not new and i replaced it when i had the first bad bat . so it was probably a good one i took out .Will report back next week when i get back to to town .Off subject I know but my camera also records sound i plan on taking a sound of the bad trasmission when it get it started again .Then will run that past all the pros .Thanks Tim for all your help and the rest of the guys .The old 8n finished up drilling in five acres of chain link posts I used the choke since the gas lever doesn't really do anything . I know it will after i put on an old carb i hafta build up ( 15 min job) putting on a old carb made the 9n run like a top after replaced the new float valve and seat with the old one the new rubber tipped ones always stick and just don't work rite.

  • If you have a volt meter, you can check if the starter is being supplied w/ energy and you can go step by step back to the battery. Try tapping the starter with a hammer and see if that gives it more activity.

  • Re: 9n won't start think its the starter hi current switch
  • Thanks Farmer Brown , if the selinoid seems to be working I will hammer the new starter ....just tap i mean .and if that does not work there may be other things that get the hammer .....Just kidding ..Thanks again .

  • Re: 9n won't start think its the starter hi current switch
  • All it takes to verify/eliminate the switch is a screwdriver or any chunk of clean metal across the terminals & then no more guessing. :)

  • That is the next try short the terminals on the selinoid then it will let me know about that unit .Thanks

  • Re: 9n won't start think its the starter hi current switch
  • Not meaning to discount what you wrote but...Generally the things that prevent the starter from turning the engine over are:
    Battery not good, (bad cell)
    corroded electrical connection(s),
    bad starter or hung up bendix,
    faulty solenoid,
    or seized engine.

    When you tested the battery did you put load on it first?

  • Re: 9n won't start think its the starter hi current switch
  • @ month old bat ----new heavy gauge cables ---no corrosion ---engine Should not be seized i will check ran fine last turn off ..I am hopeing its the selinoid i did change it out with an old one ..No load when checked bat . I just put the bulb hydrometer in each cell and it went to the best side of the green all cells . I will check the by jumping the selinoid also see if motor is easy to hand turn .Thanks

  • Re: 9n won't start think its the starter hi current switch
  • You have a 9N with a solenoid? That's unusual.

    Are you sure it's a solenoid and not a mechanical start switch?

  • Re: 9n won't start think its the starter hi current switch
  • I was calling the hi current switch ( mechanical start switch )the selinoid .I guess the selinoid is really the electro magnet that on cars spits out the starter gear on non bendix starters .Thanks again I did print out that 75 tips and that is great .
