Replacement Module For Pertronix SVDA Ignitor 1 Distributor

Did you accidentally hook your Ignitor 1 SVDA distributor up backwards or leave the ignition system on without the car running?  If so, and the car no longer starts, the module has probably failed.  There is usually a burned spot in it, which is an easy way to tell if it's no longer good.  This is the replacement module that ONLY fits the Pertronix SVDA distributors (#D186504).
