Coil – with internal resistance
These coils are designated and labeled as “Standard 805”. We have been using them on our Exchange Engines for at least 15 years and selling them in our parts catalog for almost as long with no known failures which attests to their apparent good quality. Their primary resistance measures between 3.6 and 4.0 ohms at 70 degrees F which meets or exceeds the primary resistance requirements for Atomic 4s with conventional ignition system and those with Ignitor electronic ignition systems and alternator charging rates up to 14.2 volts.”
NOTE: Except for warranty exchange, this ignition item is not returnable.
