Did you read my full message.. or just 1-2 sentences. I did explaine what i was refering to when i said 'native' 12v coil. IE one whose primary resistance is correct for a 12v application just by a function of the primary coil wire gauge and length.. IE.. no resistive element.. just plain old small copper and lots of feet of it to provide the primary resistance the best way a coil does. I think it should be pretty obvious i was not refering to "all oem application" There were too many cars with 12v systems that basically used a 6v coil with a yucky wastefull ballast resistor..... I'm trying to use some terminology to help the electrically befuddled to grasp these concepts. Seems the average 'sheeple' mechanic just can't figure out the difference in a coil made for 12v.. and a coil made for some other voltage that needs extra serial primary resistance. The coil makers that put ""FOR 12V"" in big letters, and then put "with external resistance"" in flyspec print under it are partially responsible for the electrical befuddlement that many mechanics and electrical lay people with little experience or training when it comes to these issues. When i use the term 'native', I'm refering to the fact that there is no other 'support' services needed for the device to function in it's intended environment.
Think of it like this.. a piece of computer software that natively supports a certain file format. vs a piece of software that has to use a conversion program to convert the file into a format that the software can process.
I have an engineering background.. thus much of my terminology comes from computer and electronics sources..
