I don't know much about electrics but the voltage you are getting seems a bit low, I thought fully charged should be upto 13.2 volts (2.2 v per cell x 6) and when reving the engine around 14v. Is it possible the new battery is duff? Is the starter motor OK? do the headlights get brighter when you rev the engine? You could try jump leads to see if the starter motor spins faster? have you checked to see how much power is being used with the ignition off, you can see how on youtube, not much help sorry.
