I have a 1954 Naa 6 volt that is hard to start. It used to start right up when cold and then was hard to start after it ran a while had to let it cool down for thirty minutes or so. Now it is hard to start even cold but if you pull it will pop right off as soon as you let out the clutch hot or cold. Any ideas? Thanks Don

Take your starter to an automotive electric shop and have it rebuilt.

Replace your starter solenoid, it provides voltage to the coil at startup.
This is why you don't get her to start right away.
Been there done that.
Be tractor safe

WAIT JUST A SECOND before replacing the starter solenoid for ignition problems!

From the factory, there's NO "starting bypass" on the starter solenoid on an NAA. The OEM coil is 6-Volt, and NO external resistor is used, so there is nothing for the solenoid to bypass, even if it HAD the extra "start bypass" terminal!

That diagram needs help.Lights shouldnt be fed power thru the ignition switch.Also it looks like the coils hv output is connected to the 6v line.

I AGREE on those points! HOWEVER, the part in question here is the solenoid, which IS shown correctly.

If you haven't you need to look at what Bob said since as he said there is not bypass on the soliniod so it almost can not be the problem

Make sure you get the correct solinoid for that tractor. Most auto parts stores will hand you the wrong type and that in its self will give you fits

Check your spark. You may have a starter going bad and robbing your igniti0n system of power making a weak spark. Or you might just need a good old tune up they need to be tuned up once in a while

Thanks, I replaced the points,plugs, dist.cap, plug wires,condenser and rotor and it seems to turn over pretty good for a 6 volt. What gets me is how it pops right off as soon as you let the clutch out when pulling it. It couldn't be the coil could it? Thanks

Did you use the true copper core type plug wires or did you use ones made for a car/truck. If you used the ones made for a car/truck that could be part of your problem. As far as how it turns over it could turn over good but still rob power from the ignition to the point that you have weak spark and pulling it takes the starter out of the system and it starts easy because of that. My Oliver Super 88 has a weak starter and if I jump start it it will start right up but if I don't it will not start

I bought the parts at the local Ford farm equipment dealer I told them it was for an NAA. I threw the box away but I suppose they were the good ones. The part about the starter robbing power from the ignition sounds like a good place to start looking for the problem. I going to start by replacing the starter solenoid and if that doesn't help I'll get the starter checked out. Thanks Don

The ohv Ford engine is an easy starting engine. I dont have to choke it when its warmed up.You do have to open the throttle about 1/4 when starting.An induction meter on the starter cable will tell you if the starter is drawing too much current.I have had two of these meters for over 50 years.You can buy one for 7 bucks.A small hydrometer costs under a buck.Dont be a parts changer.I never could afford it and if you do it on customers equipment you wont get much work.Small chance that the solenoid is the problem.It could be jumped with short cable to prove it in 30 seconds.Shouldnt have to tell you to make sure the transmission is in neutral but thought I had better.

Thanks for all the help I'm going to check the plug wires and make sure they are the copper type and then check all my connections to make sure they are clean and tight. Then I'm going by the parts store and pick up an induction meter and check the starter. I'll let you know what I find out. Thanks again for all the help.
Don

Youv'e been told 4-5 times now that it is not the starter solenoid. If yuo have the cash to burn, and just want to repalce it to make it new and shiney.. go ahead.. but it will have -0- to do with your problem. Also.. if you bought OEM ford wires.. there is a good chance they are carbon core.. not copper core..

I'd check all electrical connections and ground for clean-bright-tight... and then check the starter itself out..
