I installed a bluetooth radio. All going well but I had a slight hick up installing it and caused a short and blew fuses. Everything is working fine apart from the cigar lighter. I need this to power the iPhone. I have checked the fuses under the steering wheel and the bonnet, I can't see any blown by a quick visual inspection.
Does the lighter have another fuse somewhere or will I have to remove the fuses one by one under the sterling wheel and give them a closer look, bloody awkward to get at. Usually I know a blown fuse without having to take each one out. The wiring where the radio is was non standard, the colors were wrong would you believe hence a fuse blew but I don't believe the cigar lighter routes that way, it wouldn't make sense. All I used for the radio was ground, ignition toggled 12V and, permanent 12V. According to my guide its a 40 amp fuse. Unless the diagram is wrong, the 40amp fuse under the steering wheel is fine, I tested it with a meter.
I must be missing something very basic here, embarrasing given that I repair computers for a living

Also as I'm on the subject, the lighter used be on always, I want to change it to be toggled by the ignition so whats the best way to remove it and check the wiring.
Thanks guys,
Chris
