Ok I will try it all and see what works better. With regards to the starter. I put my multimeter on it and compared it to an old generator starter that I have. Sorry bout seeming a bit clueless but it's the first time I've had to do with this side of things so learning as I'm going.
The switch only has 2 cables coming out of it which I believe connects to the battery solenoid and then the start I've removed the cables and other brackets at present until I can get it to crank over properly so I don't have to keep taking things of and on hopefully the vid shows what's happening when I short the starter hope this helps
