I purchased one of these http://www.ebay.co.u...=item43aa77f0ad yesterday and it droppped through my door this morning.
So off to the garage we went and plugged it all together, whipped out the multimeter and sure enough there's a lovely constant 12v to power my fan again!
Considering the replacements are £25-£30 i figured a £2.49 gamble was worth the risk. And it paid off!
Heres a pic of how i wired it...
