Convertible Top Not Working

The circuit breaker in My 67 Dart is located on the top’s dash switch.

These top switches are not the most robust, and its breaker is rated at 30 amps. You may want to rewire this circuit using two relays triggered by the dash up and down switch. One relay would be for up, the other for down. By using relays to do the heavy lifting, the amperage passing through the dash switch would be reduced to about one amp or so prolonging its life.

I made this modification on my car several years ago.
