Hello. First post. I have a 1970 Lemans sport with a 350 center consule auto. I was driving it last night with my 2 yr old daughter in the car seat and I slow down for a stoplight and came to a stop and I cranked up the blower motor and everything just went out completely. A good Samaritan pulled over to help me and we tryed to jump it. No luck. Everything is dead. No headlights. Flashers. Cranking or anything. Put it in a parking lot I’m gonna have to go back and try to fix it tomorrow. Where should I start? All the terminals and Cable’s appear to be in good shape with no corrosion. Could this be in the ignition switch issue? I’ve just never seen no power meaning usually you would have dim headlights etc. It’s almost like the blower motor pool too many homes in short something out. Is there a fusible link somewhere?
