You need to check the coil resistance, if it is too low the points will burn. Then to fix it you will need another proper coil or a resistor in line before the coil. If you put 12 volts to the points without the coil that is the same as direct short to ground. If it has always burned the points the voltage to the points is too high.(same as too low resistance) Also the condenser can cause points to burn.

The more help I ask for the more I'm getting confused. So what should a coil resistance measure? How many ohms...under current or at rest? This mess all started when I left the key switch on after running out of gas & all my ignition parts & wires got ruined. I bridged the in closing them by moving the adjusting plate over & closing the old points just like they do in normal operation with key switch on. I was just replicating what happens when I leave a key on with the points closed. That's when I seen things heat up in just a few seconds. This was all done before I replaced the coil, condensor & the new points. But what I need to know is why did all this get wrecked in the first place? I just want to prevent this mess from happening again. Where should I put a fuse if I need one & how big?
