Cub problems

I recently purchased a 1949 Cub. The guy I bought it from said it was converted to a 6-volt from a 12. Also, the battery has to be recharged almost after every use. I had the battery checked and it came back ok. Any thoughts about both of these items? Should I have it changed to a 12 volt? Thanks.
 
I would think it odd to change from 12 back to 6 except on show tractors that have collector value. The 6v generator looks like a fat thermos bottle. The 12v alternator is shaped like a 8 inch mushroom about 4 inches thick. I would suspect you have a 6v battery and a nonfunctioning alternator. Can you post a picture or two?

Well, you have a magneto that has been modified to use a battery and external coil. If it runs OK that is one way to do it. It is far from stock. Your question involved the charging. The charging device is under the hood and has a belt running to it.
 
It takes over 12 hours to charge the battery. I don't have a crank to try starting it. Just wondering if something is pulling more amps out of the battery to cause me to have to charge it everyday.
 
If you charge it all night it should run for at least an hour. Turn it off and>unhook one of the battery terminals. There should be no sparking when tapped on the post. If you have a multimeter there should be no voltage present between the wire and the post.
The switch should prevent voltage from getting to the coil when pushed in. The original switch shorted out the magneto when off(in). It needed to be changed to one that does not conduct when pushed in .
I would unhook the battery when not using it until you get it figured out
 
looks like a magneto, on the tractor. when the engine starts, you can un hook the battery. it will , it should run all day and then some. you probably have a dead short, somewhere

I did, as you suggested, started up the tractor then disconnected the battery. When I did this the tractor died.
 
I'm wondering if the coil is wired to constant 12vdc and so is slowiy draining the energy.

If it has a 6v coil and a 12v battery it could be the ballast resistor.

Or, if an alternator is fitted it could be the field in the alternator as a drain if a diode is not present to block the current flow when the tractor is off.
 
The ignition device was a once a magneto. Now they are only using the points to fire a conventional coil ignition. The rest of the coil is not being used. When the old stop switch is pushed in it shorts out the points resulting in a stop and a deadly drain on the battery. Soon the points will be toast. Then it will neither run nor charge.

What is your best suggestion? I just bought this tractor for $800 and I really like it. I want also find a belly mower for it too. Is it costly to have it returned to stock start up?
