There appear to be 5 fuses attached to the + terminal (4 underneath and 1 just on the top right) all appear fine.
I'll check the ones in the engine bay a little later as have to go out. Hate to say this, but where are the fuses inside the car mentioned above?
something HAS to be a fuse! do not under any circumstances use anything but the correct rated fuse. disregarding this will potentially leave you with a burned out heap in your drive and no insurance pay out.
