1. An electrical short circuit protection device for a controller for at least one vehicle electric wheel brake, the electrical short circuit protection device comprising:
- a vehicle power supply;
an electric wheel brake controller having a short circuit protection device, said controller also including an input terminal and an output terminal said input terminal connected to said power supply;
current interrupting device which is separate from the brake controller short circuit protection device, said current interrupting device having an input terminal and an output terminal, said current interrupting device input terminal being electrically coupled to said electric wheel brake controller output terminal and said current interrupting device output terminal being electrically coupled to the vehicle electric wheel brake, said current interrupting device being operative to interrupt an excessive flow of electric current from said electric brake controller to the vehicle electric wheel brake; and
a device which generates a warning signal electrically connected across said current interrupting device.

Abstract
An electrical short circuit protection device for an electric trailer brake controller includes a fuse connected between the controller and the trailer brakes and an acoustic piezoelectric transducer connected across the fuse. Upon a short circuit fault developing in the trailer brakes, the fuse opens and the transducer generates an audio warning signal.
