Turn the bass all the way down and the treble all the way up. Adjust volume - louder is better, but too loud causes distortion and therefore 'R-Tape Loading Error'.
If the computer is 'hearing' anything after you type ' Load "" <enter>' then the border should flash between red and cyan, regardless of whether it's data or not. If you play a music tape it'll still do this.
When loading, the first thing you encounter is a header block.
The noise will be something like "dooooooooooo dit!" (with a scrolling cyan and red border) and the ident will appear on the 'dit!' part.(Program: HORACE) - something like that. If you get that far it's working.
Get a multimeter with a continuity tester. Test continuity on the data leads - on both of the tips on a single lead after the black spacer, then on the body of the plugs before the black spacer. If you get a good continuity reading you can discount the leads as the problem. If they're knackered (and you have any small electronic skills) then you could buy a couple of mono jack plugs, a soldering iron and a length of mono wire from Maplins for peanuts. (I'm assuming you're in the UK.)
To load software you only need the 'ear' lead connected ('ear' to 'ear' on the spectrum and tape recorder if I remember correctly) therefore if it doesn't work on one side of the lead, try the other.
If this still doesn't work (and you're not adverse to cracking the speccy open) continuity test from the 'ear' socket along the copper track on the motherboard to see if the signal is getting to where it should be. There could be protective paint or resin over the top of the track, so you might have to give it a little dig with the pointy end of the probe to get a signal (if you're sure you wouldn't break the track doing it of course.)
