:doh::doh::doh::doh::doh: and you didnt think to mention this in your orginal post
lol apologies and i am a noob and was told by the auto electricains that it was not an auxillary issue but to do with the main circuit on motor hence why it was not mentioned!
Still have another issue though as the monitors don't work - ohh well at least without a battery drain i can take it to an audio specialist to sort before it gets exported overseas!
