It's with an ordinary Halford 4amp max. charger, but I'll give it go with a bigger fuse. It blew one before I turned the charger on though.....

Do not put a bigger fuse in! The fuses are there to protect your kit - if they are blowing, there's something wrong.
Keep the charger disconnected from the bike, and look at each separately first.
Firstly, the bike. The power socket (1150GS, by your left boot) is permanently 'live'. Check that you've got 12v coming out of that by pluging any 12v device that you have with a DIN plug on it into the socket - maybe a tyre pump, a GPS, a torch, voltmeter - anything! Verify that the socket works. If it doesn't, take the starter motor cover (the bit of plastic that it's mounted on) off and ensure that the lead is connected at the back. Try squeezing the connector to remove it from the back of the socket. Use a voltmeter to see if you get 12v from the wires. If you don't, the fuse under the seat has blown. Replace that and then run the voltmeter check again.
While you have the socket in you hand, what does it look like? Is it full of sh1t and crap inside? If so, clean it out. Use running water and your toothbrush inside. A drop of oil on the cover spring will keep the cover working well and keep most of the sh1t out in the future.
Reassemble and turn to the charger.
How well did you wire the plug? Does it look really neat inside? No frayed wires? Did you tin the bare ends? Is it shorting inside the plug?
Plug the battery charger into the mains. Attach your voltmeter to the terminals. You should get about 14-15 volts DC. Use you voltmeter to ensure that the polarity is correct. The +ve should go to the tip of the plug.
If you found nothing wrong, plug the charger into the mains and the bike - it should work. If it doesn't, bring it all round to my house!!
