I can get you the serial number I was told late 1952 the reason is I have power to the starter but when I push down the lever to the starter it does nothing no noise just silence so I was thinking to just make it hand start since it has decompression petcocks
 
Going to be way easier to fix the starter than trying to convert a 52 A to hand start. They did make a adapter to start it with the steering wheel through the flywheel opening but it's not easy to start them that way. Pull the cover off the bottom and take a look inside. Might be just the switch on the starter. See if your getting power there. Could be a battery issue. It's not that hard to pull the starter out. Good Luck!

Your going to spend more time screwing around and wasting money. Just fix the stater and you will be much happier in the end.Most likely the contacts on the starter switch or a ground issue.
 
Ok thanks for your time Ive had the starter out several times it works on the ground but when I put it in the tractor it wont make a noise or do anything I have all new wiring on the tractor the brass on the starter switch is a little worn it has a small screw on the side of that switch but no wire on it ? Not sure if there is supposed to be a wire there
 
brand new ground cable I used a grinder under the bolt so Im pretty sure I have good ground I was told its positive ground not sure how to check that ?

Have you checked the copper contact, under the triangle thing on top of star, for wear , with contact button to inside of the starter?
 
99% of the time I've had a "NO STARTER TURN OVER" it has been (Both A & AR styled)a problem inside the component that I have circled on the picture. Proper length of rod from Hand / Foot lever also has caused issues...
The same on y JD 520...

Since there is power at the starter switch, then push the button to engage the starting motor.

If the starting motor engages, then check and/or adjust the starting motor pedal and linkage.

After checking and/or adjusting the starting motor pedal and linkage, then push the starter pedal.

If the starting motor does NOT engage, then remove the starter switch and check for wear on the copper contact.

If the copper contact is severely worn on the edge, then it may not be making a good connection with the stud terminal on the starting motor.

Inspect the stud terminal on the starting motor.

If the stud terminal is severely worn, then it may not be making a good connection with the starter switch on the starting motor.

You might consider replacing one or both if they are severely worn.

Hope this helps.

This type of switch allows a tractor to be set up with the popular ballast resistor bypass for starting only option.

Take a look at the diagram below.

a155461.jpg" width="650"


Note the black wire that is connected to the starter switch and ignition resistor.

Take a look at the photos below.

a155462.jpg" width="650"


Note the side terminal on the starter switch.

a155463.jpg" width="650"


Note the black wire connected to the side terminal on the starter switch leading to the ignition resistor.

a155464.jpg" width="650"


Note the black wire from the starter switch connected to the "output" terminal on the ignition resistor.

When you press down on the starter pedal, 12 volt power temporarily goes directly from the battery to the ignition resistor and coil at start up.

Take a look at the diagram below.

a155465.jpg" width="650"


If the ignition switch is [b:654c4848f0]ON[/b:654c4848f0], then once you release the starter pedal, the power comes from the ignition switch to the ignition resistor and coil.

Hope this helps.

The battery cable that is "[i:654c4848f0]ground[/i:654c4848f0]" connected to the tractor body is connected to the POSITIVE <BIG>+</big> post on the battery.
 
the copper stud on the starter is definitely worn not sure where to buy one at Im going to get a new starter switch also and there is no black wire off the side of the starter switch where would that wire go if it was on there or does it not need one ? And I have adjusted the rod for the foot pedal to starter thanks
 
Where is it grounded? If the new ground
cable goes to the battery box the problem
may be a poor connection between the
battery box and the frame of the tractor.
If you hook a jumper cable to the battery
ground and hook the other end to the
transmission housing you can check it.
 
I have it grounded on the back side of the tractor under a bolt it was grounded to the battery box but not anymore I have 12.6 volts at the starter

It would either be connected to the NEGATIVE terminal on the ignition resistor.

If there is no ignition resistor, then it would be connected to the NEGATIVE terminal on the coil.

Note that the 52 Model A was not originally designed with an ignition bypass resistor.

Hope this helps.
 
A wite should run from the stud on the
starter to the amp meter. This feeds the
ignition.
 

There is a white wire to the amp gauge off the starter and a positive wire off the starter to the negative on the battery I have no wires off the starter switch could that be my problem?
 
The 12.6 volts at the starter doesn't tell you a lot, what you want to know is what the voltage at the starter is when you are trying to run the starter. A bad power lead or ground will show voltage when the starter is not engaged but will drop to nothing when it is engaged.

Also, 12.6 volts is a little low for a 12 volt system, it should 13.5 or so.
 
For no expense at all, put the tractor in neutral, engage the clutch, turn on the
key and start it by turning the belt pulley. Takes a pair of strong hands.....

Test for power at the NEGATIVE terminal on the ammeter.

cvphoto69228.jpg


Test for power at the POSITIVE terminal on the ammeter.

cvphoto69229.jpg


Test for power at the BAT terminal on the voltage regulator.

cvphoto69230.jpg


Test for power at the L (LIGHT) terminal on the voltage regulator.

cvphoto69232.jpg


Test for power at the ignition switch.

cvphoto69233.jpg


Finally test power at the NEGATIVE terminal on the coil.

Repair or replace parts as necessary.

Hope this helps.
 
Another thing to check would be how clean is where the starter mounts to the tractor. If the starter case does not ground well to the frame it is not going to work either. Had this problem on one of mine.
 
I tested for power as you described in the pictures I have power in all except I have no power on the L (light) on the voltage regulator would that cause the starter not to work ?
 
"[b:654c4848f0][i:654c4848f0]no power on the L (light) on the voltage regulator would that cause the starter not to work[/i:654c4848f0][/b:654c4848f0]"

No.

Power to the starter comes directly from the battery.
 
I had to troubleshoot an Allis Chalmers a couplers ago with an issue like yours. The issue was the power cable from the battery to the starter. In your case the Negative Lead.
The lead was corroded internally and was not allowing enough correct to pass through to energize the starter.

Unhook both ends of the cable and temporary install a jumper cable from the battery to the starter. See it this works.
