Its now working.

I removed all the links to the relays apart from the coils - tested and it appeared to energise. I then googled the datasheet for the relays and found that the contacts where wired differently to the other relay (NO / NC then the comm rather then NO / comm / NC) - rewired the stripboard (now quite a mess) and it works (well I get 5v out to the motor when the pic energises the relays )

Thanks to all who contributed - and I'll note that formula for working out the resistances - Cheers Henrik
