Calypso

Hi Guys, I recently bought a Calypso Blue KE55. All going well until brake lights stopped working. Suspected dodgy stereo install from previous owner. Fuses keep blowing as soon as I replace them. Have removed all sub and amps to isolate problem. Still blowing fuses immediately and draining battery. Suspect a voltage leak somewhere. Unplugged brake pedal switch and still measuring 12 volts across the fuse holder. Can anyone recommend a decent auto electrician (inner west / artarmon) or solution to my problem? Cheers, Tim
