ok im pissed off now.took the starter out, left it wired in and earthed it. got my mate to turn the key for a second and let it return.the starter did as it should, tried again and again and everytime i did, the same thing happened.

i now have no idea wha else to check other than takin the box off and looking at the flywheel but it looks ok when looking through where the starter bolts on.. heres a pic...
