Depending, hazards and turn both work out of the same relay, and thus, fuse.
Not always the case , four way ( hazard) flashers, are wired on a separate fuse and have there own flasher on many chassis, in a battery feed , so they will operate if all ignition circuits are dead.
Regular signal lights operate only when ignition is on.
Is this a F53 chassis?
