12 volt alt on a cub

tedregentin · Jan 20, 2013

I recently purchased a 1962 Cub that has been converted to 12 volt negative ground. I have been getting it ready to use, and I noticed that there is no cutdown resistor to the dist. I converted over my dad's C many years ago, and I don't remember what I used. Any one have any suggestions?

If the original 1.5 ohm coil was replaced with a 3 ohm coil during the 12V conversion, no resistor is needed.

f it ain't broke , don't fix it. You need not go through life looking for troubles....enough will come your way anyway

If you have an accurate amp meter (beyond the approximation of the dash gauge), it can be used as follows to see if there are issues. Remove the lead on the coil going to the distributor. Connect the meter between ground and that terminal on the coil. Turn on the ignition and look at the meter. 2.5 to a max of about 4 amps is OK. 6 amps means the coil is in need of a ballast resistor. A easy to find and cheap resistor is from a 1966 chevy 6 cylinder pickup truck. Jim
