SORTED, Cheers anyway

what was the problem in the end??

yeah i wudnt mind knowin what the proble was either i was quick entregued by this 1

First of all i needed my grounding wire to be as thick as the power wire, and then i also needed a bigger fuse on my power cable. That sorted the problem for me.
