New guy with a 1962 Cub

Postby Griffinsark » Wed Jun 12, 2019 10:51 am

Hello everyone! I read some posts, read the welcome wagon, updated my profile and now I'm posting for the first time. 6 volt positive ground... I'm starting to get it. To bad the guy I bought it from didn't. Fairly new battery in the tractor with the starter cable hooked to the positive post. I slipped a 12 volt battery on it to get it started and let the smoke out of the lights/charging switch... Pulled the carburator, no gasket between the float and main. Amazon brought me a rebuild kit and a resistor. Now I guess I have to find a new light switch. BTW my tractor came with the original owners manual. I think the original spark plug wires also. Seems to have had the points and codenser replaced though. Who has udated to twelve volts but uses a resistor to lower voltage to the points?

Welcome to the forum. After two posts, you can access and download manuals from there. Just click on the "Quick Links" on the upper left and then scrolled down to "pdf manuals".

It is possible that the previous owner re-polarized the generator to make it negative ground. That would explain burning up stuff when you switched it. If you use the search bar at the upper right you'll find lots of threads on the 12V conversion as well as instructions to set generator polarity.

Most electronics seem to run on smoke. They quit working as soon as the smoke comes out of them.
Your light bulbs may have glowed extra bright for a second or two being connected to a 12v battery. Seems like you need to determine if your tractor is still a 6v positive ground or been converted to 12v negative ground.

Welcome!
As said above read the posts on 12v conversions and 6v systems. To give a quick answer to your question for a 12v conversion you’d use the standard 6v points and condenser with a 12v coil that has an internal resistor.
One of the last cubs I brought home had a 12v conversion done by the prior owner. He had put a new coil on but it was still for a 6v system. The 6v coil heated up and it barely ran with 12v running thru it. The right coil made all the difference.
I had asked the PO if he knew of this forum. He never heard of it and I think if he had with the collection of experience here helping he would have had the problems figured out. He probably wouldn’t have sold it.
I guarantee any issue you encounter with your Cub the people here will graciously come to your aid to help you figure it out.

I have done several 12 V. conversions using a Chrysler ballast resistor with the original 6 V. coil. The ballast resistor is less expensive than a 12 V. coil with internal resistor.
I have an excuse. CRS.

The 6v battery that came with it and was ( I believe) hooked up backwards won't hold or charge. When I hopk up the battery charger to it correctly the battery charger says it is hooked up backwards. I can't disconnect the battery while the motor is running. When I read the voltage at the battery while the motor is running I see 8v with the motor off I see 12v. It appears to have a replacement alternator so now I have to open the cowling and verify the alternator is a 6v positive ground. Seems likely since the 6v battery was ruined. Off to read conversion threads! Thanks!
