yes zero voltage at alternator output. i traced wire to firewall and found this. is this my fusible link? some context: the car died died at a traffic light. i jumped her and she ran off battery to a parking lot. i replaced the alternator and voltage regulator still no charge at battery.
aloha, i’m fortunate to have a 1971 340 numbers car. my parents first new car was a 1971 challenger. she stayed in the family until the mid 90’s. if we knew then what we know now i wouldn’t have had to buy mine seven years ago. drive safe
