Hi Banjo,
Thanks for fast reply. In my car don't have ballast resistor..it's 12v connect direct to coil since long time but can start normally even 2month not start at all..this prob occurred recently.
Ignition switch have 6wire does need any wire loop together because if release key after cranking then only engine plug will spark.
Or explain me how ballast resistor work I'm still confused on that..
