Are there other single faulty things besides main fuse, starter relay and main earth that can kill the entire system?

It could well be the battery. It may well 'appear' fully charged and read a decent voltage with nothing connected but as soon as a load is applied the voltage can drop to such a level that nothing will work. It is not unheard off for duff/old batteries to give 12.8V between their terminals after a fresh charge with no load but only to drop to half that when even the tiniest load is applied and the internal resistance rises due to plate or electrolyte damage/contamination.

Put a multimeter across the battery terminals with ignition off with the battery disconnected from the bike and note the voltage - it should be 12.6 - 12.8V for a good serviceable battery. Connect it to the bike and take another reading with the ignition off - there should be little or no noticeable voltage drop from the first reading. Then get a third reading across the terminals with the ignition on (but engine not running) - there should be no more than a 0.2 - 0.3V drop from the first reading.

Get back to us and post these voltage measurements. It should be possible to determine fairly easily whether your 'fully charged' battery is actually dead when under load.

Thank you for replying. I've measured as you suggested now and got 12.7 V with the battery dismounted, mounted and ignition both on and off. The only odd thing was that the volt meter slowly crept up to 12.7 with the battery off the bike, but instantly showed 12.7 when it was hooked up to the bike.

This main earth that the OP found to be the cause of his problem, do you know where it might be and how one tests it?
