Turn signals not working, blowing fuse
This is a colorized version of the turn signal operation.
The orange represents the switch contacts signalling left.
The contacts connect the power from the flasher unit to the wires on the left side.
When the brakes are applied at the same time, power goes through the stop switch, through the hazard switch to the cener contact of the turn switch and right side rear wire.
Turn signal flasher unit gets power from the keyed accessory circuit. No fuse. The flasher itself is essentially a circuit breaker.
Brake lights get power from the main splice. Key off doesn't matter. If that fuse is good, they get power.
I think you're familiar with this but if not
