Hei /6 won't shut off?

I can only guess that a wiring error in relay circuit, keeps it energized, once it is enabled.

If you show circuit diagram of all related connections, we might be able to help.

Thank you for your replies gentlemen! I followed Dan's tutorial to a T: Mopar Owners Group South Africa • View topic - HEI (High Energy Ignition) Retrofit How-To
Trigger wire off when ignition off....think I found the culprit though. Voltage to ignition switch via pilot light connection, disconnect from alternator and she shuts off. I will replace the ignition switch and take it from there.
