Hey folks,

1970 340-6 Challenger with electronic ignition kit.I turned the key, heard a loud "click" from the engine bay on the firewall in front of the glove box (ECM? Voltage regulator? There's a ceramic resistor over there too), then all power was gone, no ignition, dome light and headlights were out. I checked the ceramic resistor and it "looked" okay, no burns or flash marks.

I replaced the starter relay. Had lights and power. Turned the key and same thing. Loud "click" in the engine bay but no maybe lower down by the starter.

Any ideas as to where to start testing?

Thanks!
