I've a '67 b-body. I replaced the master cylinder, and when I hooked up the brake light switch (switch was bench tested and current flowed through it) I had no brake lights nor parking lights; turn signal lights do not work. Fuses are ok; headlights work (though they are on relays). Question: when I disconnect the turn signal flasher, should there be power at the connector when the headlight switch is pulled on? I'm not getting power to the connector. I bench tested the turn signal flasher and when connected to a battery (9 volt) there was current running through the turn signal flasher (I guess this means it works?). Prior to replacing the master cylinder, everything worked.
