[Lee W.]

1972 cuda Had to jump start the car it started ran for about 15 minutes turned it off. went to auto parts got new battery hooked it up now I lost power to the whole interior. ignition switch, head lights, turn signal, dash lights. not the battery can jump across the solenoid engine turns over wont start. Thanks for any help you can give

make sure to grab your PDF of the service manual, for your reference. The wiring diagram will show the majority of interior power is fed from the battery POS terminal, through the fusible link (these can blow) and on to the bulkhead connector, where it is picked up by the fuse box and interior wiring distribution.

Since the battery was recently fiddled with, I'd start at the battery POS terminal, and follow the flow back through to the fuse box and ignition key.

Did you change anything other that the battery? Perhaps the battery cables? Is the GROUND to engine and chassis still good? You may have something simple like a loose connection near the battery on the fender well.

Clean the battery terminals so the shine like a new nickel. Fuse able link start there. move it around see if things come on. Then the bulk head connector. then the plug under the steering column. Check battery grounds.

Probably blew the fusible link.
Low battery voltage will result in higher current draw across the link.
