I have a '45 H that will not turn over at all with a fully charged battery. The starter was recently rebuilt and when I pull start it, the tractor will run good for about 15 minutes and cut out. At that point I can almost get it to turn over again, but not completely. I feel like the problem could be the generator but I'm not sure. Any suggestions? This is a 6-volt with push button ignition. I've gone completely through the wiring and I'm certain that it is not grounding out.

Make sure you have the battery in right, and that the positive (+) side of the is being used as the ground. When we had our H painted the painter put it in backwards, and we had problems like you are describing.

Try shorting across the starter solenoid with a screwdriver with the tractor in neutral and the brakes set. Be careful when doing this. Have you
measured the specific gravity in each batery cell?
These readings should be very close to one another. Should be around 1250-1275. Hal

What you are describing could be two separate issues. The starter could be a bad switch on the starter and the dying could be from a coil or condenser that is going bad. The first thing I’d do is replace the condenser and take a look at the starting switch. A lot of times the contacts in the switch get pitted or “burned” and won’t make good contact. Now, come to thing about it when you say “push button” could this have a solenoid in the starting circuit? If so that could be going bad and not powering the starter properly. I have also tested starters by hooking up jumper cables directly to the starter from a 12-volt system. If the starter rolls good then, likely it is in the wiring (including switch or solenoid) between the battery and the starter.

Is the motor hard to turn by hand ? How sure are you that the starter is still good ? What does you hydrometer say about the battery ? What does a voltmeter say about the generator at WOT ? I've got a 6V battery that I had given up for dead last winter, that still starts my H with the higher compression pistons.

When it quits after 10 minutes, do you still have spark ?

You may not be getting fuel to the carburetor or
the coil is weak. Do you have fire to the plugs when it quits running? Hal

I thought the fuel line might be the problem originally, but I've clean that and the sediment bowl with no results. I am positive that the carb is getting plenty of fuel. Plugs are good. Kyle

You should be using heavy battery cables with solder spades. Make sure the grounded area is free of rust or paint and all connections are tight. Heavy welding cables cut to the exact length make good batery cables. You can probably buy them where truck tractor parts are sold. Hal

I am using welding cables for my battery cables. I am confident the the battery is grounded and that all connections are tight. This is a very clean, well maintained tractor. This problem has only recently happened. Very frustrated. Kyle

You mean the starter will not roll the engine over when you press the button, right?

Then why is everyone telling you to check the fuel lines??? Solve the "cuts out after 15 minutes" problem later. Get the tractor so it will run first.

What happens when you push the button? "CLICK?" Nothing at all?

How confident are you in the quality of this so-called "rebuilt" starter? It wouldn't be the first time someone did a hack-job on a starter rebuild.

Hook a $3 Harbor Freight voltmeter across the battery terminals. Hit the starter button. What happens?

If the voltage doesn't go down, you don't have a connection, and your "shiney tight" connections are the problem. One or more of them is neither shiney nor tight.

If the voltage goes to zero, you've got a bad battery, bad starter, or a dead short in the system.
