  • Selinoid just clicks
  • WellI figured out how to fix my tractor hydraulics. I used it yesterday for a while. I was blading the driveway and it just died. I had the battery checked. It's good. When I push the start button the solenoid just clicks.

  • The starter was fired. Got it fixed today. The old girl lives.

  • A common and often overlooked problem is corrosion where the battery ground cable connects to the frame. Did you clean that? Are your cables in good conditon.

    Also, where is the ground cable attached to the frame? If it is still connected to the framework around the battery holder, get a longer ground cable and run it to the tractor body as close to the starter as possible. I have my side mount 8n grounded to one of the steering system bolts to rear of starter.

    The battery support has several bolt connections it needs to go through to get to the main frame. Each connection is a potential for corrosion and high resistance.

  • Your battery most likely isn't getting charged, so, STOP replacing parts and don't try to jump start it. If it is wired wrong, which is the usual case, you don't want to do further damage by applying power. The usual root cause problem of the starter motor solenoid just clicking, 8N and up models, 9N and 2N never used a solenoid, can be traced to a bad/weak battery. How did you test it? As I read down your posts, I see you say it is a 12V switch over job. Now I suspect your problem is poor/incorrect wiring. I concur that just replacing parts and wasting money is foolish without first determining of part is defective or not. First, starters don't care if 6V or 12V (see JMOR's reply) so NO, buying a 12V starter is a waste of time and money especially when you don't know the condition of old one. Rebuilding the OEM unit, is always the first choice on these old Fords. There's nothing wrong with a 12V conversion if done for the right reason, but so MANY are simply done incorrectly. SEE LINK below to our HOW-TO's/ELECTRICAL forum for WIRING PICTOGRAMS by JMOR. Scroll down to find your setup -forget serial number, go by whether a front mount or a side mount 8N, then download a copy for yourself. IF it is a front mount distributor, you need the OEM Ballast Resistor in the circuit on any 12V conversion. If the front mount coil is 6V, you need to add the external 1-OHM ceramic resistor in-line. You can switch the coil to a 12V unit and discard the external resistor (best choice) but NOT the ballast resistor. The Pictograms explain things thoroughly. On a side mount simply switch the coil to 12V as well -side mounts don't use a Ballast Resistor. Next is to go thru the wiring completely and ensure it is all correct –take NO shortcuts. It would be wise to get the battery tested the right way. A battery must meet specific gravity and sustain a full charge under load. A hydrometer can be used but, if you take your battery and starter to your trusty local starter/alternator shop they can bench test them with the right equipment. An auto parts store can usually test the battery but I know of none that will test/rebuild a starter -they usually farm out those to the local shop guy. Begin performing a thorough, root cause problem solving method before applying power. Report back with a follow up on your results.

  • Re: Selinoid just clicks
  • Ditto what Dean said.

    Make sure that starter is not jammed into the flywheel.

    Regardless, you need to trouble shoot the problem, not just throw money at it.

  • Re: Selinoid just clicks
  • Assuming it is an 8N you are talking about (has a solenoid and this is an N board) sometimes the starter will stick. If you put the tractor in 4th gear and rock it back and forth with the tire that will usually pop the starter loose. I have had to loosen the starter bolts and tip the starter away from the flywheel once for a friend when that happened to him near a creek and a big rain was expected. We could not rock the tractor because a heavy implement was on the ground.

    I would not expect the tractor dying to be related to the starter issue.

    Just a thought.

  • Bad or dirty connections on the battery and starter cables. Clean everything up nice and shiny and see how it works

  • Re: Selinoid just clicks
  • I cleaned everything throuly. More information I converted it to 12 volt 3 years ago. I have the original selinod and starter on the tractor. It has been just dying lately. Now it just clicks. Should I buy a new starter, selinoid and coil? I tried jumping the starter off the battery directly and no luck.

  • The starter might be bad; you ran 12 volts through a starter that was made for six volts. It will spin over faster but it is not really good to double the voltage on a device for a prolong period of time. It is sort of like doubling the voltage on a light bulb, it will burn brighter but have a much shorter life.

    Also need to address the dying issue.

    Need to give complete information on the 12 volt conversion that was done.

  • Re: Selinoid just clicks
  • Yeah, my 8N with 6v starter and 12v battery/alternator has ONLY been functioning for 50 years.

  • Re: Selinoid just clicks
  • Well, I would say that is a good thing, wouldn't you? However, as an electrical engineer; or at least one with a degree even if I could not work as an engineer, I still say that it is not good to double the voltage. If the tractor starts well then the amount of time it spins is short and might last a long time. However, if it doesn't want to start, I wouldn't keep the starter going for too long of a time as you could burn the windings out. I=V/R; the resistance of the windings is going to stay the same. So doubling the voltage is going to double the current. The higher the current, the higher the heat generated in the windings.

  • Re: Selinoid just clicks
  • then you probably also know that a low battery voltage will put higher current thru a starter motor than a good full voltage battery. A motor is not a pure resistance load, ya know. back emf.

  • Re: Selinoid just clicks
  • I replaced battery alternator coil and the ceramic block. I can purchase a 12 volt starter. And solenoid. Just curious if anyone else has a trick or opinion before I spend the money.

  • Re: Selinoid just clicks
  • Try jumping from the battery to the starter and see if it turns over. Make sure the tractor is in neutral. If it doesn't the starter is bad. If it does you need to check for voltage going through the solenoid.
