Robb..... ....it pleases me that you've shown initiative and did some research in the "archives" about your friends frontmount 12 volt conversion. As one member sez: there are many ways to convert to 12 volts and some of them even work. The simple test to differentiate between 6 or 12 volt frontmount ignition coil is with an ohm meter. Realize ohm meters are not very accurate at low resistances like the ignition coil primarys so the exact ohm value is not that important. If you understant that concept, then a good 6 volt frontmount ignition coil will read about 1 ohm resistance. A good 12 volt frontmount ignition coil will read about 3 ohms. About a factor of 3 difference. The secondary for both coils will read about 5000 to 10000 ohms, a very major difference from the primary. If you choose to use the modern 12 volt frontmount ignition coil, (which I recommend), you STILL must have a current limiting resistor of 1/2 ohm 10 watts from radio shack to keep from burning out your new 12 volt coil. DO NOT USE the original OEM ballast resistor with the 12 volt coil. It is the WRONG value resistance by a factor of 3. Do you under stand that? ..... ..... respectfully, Dell
