Would 12 volts on a 6 volt system kill your ignition system if its not converted?

    It won't harm the points.I used to do 12v conversions on 6 v cars all the time.The resistance wire is in the hot lead to the coil.When I did a 12v swap I used the 6volt starter on 12v no problem a resistor to slow down the wipers used a 12v alternator with a built in regulator a 12v coil with an internal ballast and changed all the bulbs and the radio.

    I had a 12 volt battery hooked negative ground and positive hot in a 6 volt tractor. It ran surprisingly a long time. The ground overheated at one point and the battery blew up, and eventually no spark.

    But so did my grandpa, so I'm not sure what was all going on. If I fix the tractor I might as well 12 volt it? I'm prob gonna have to replace all components anyway and the gauges are all toast from water damage.
