Motor Testing: No Load

OK, I have now sorted out the motor and tested the controller and everything is working great. I bought the control box from kelly controllers so I could test the motor and controller before mounting it firmly, just in case there was something wrong or if I messed up the hall sensor cables. It took me a while to find it but I looked on the site and found the diagram for the wiring (with colours). Found here: http://www.newkellycontroller.com/product_info.php?cPath=21_62&products_id=135

I used 48v of oldish lead acid batteries I had lying around, which sufficed. Although I connected them to the chargers so I would be able to see it at max voltage. I need to get a speedo hooked up. Will go to a bicycle shop to get s cheap one for tests. I bought a motorcycle speedo, electric and uses a sensor too. This one: http://www.kosonorthamerica.com/fCMSBackend/imgRoot/specs/bb017b00.jpg

Which I probably plan to hook up to one of these to get reading of the batts on the actual normal Petrol tank reading;http://www.evworks.com.au/index.php?product=INS-EVW-FGD

At first I had connected it wrong. Because I wasn't going to use the main contactor I had put the precharge resistor in series on the positive cable. Which meant that it was acting like a voltage resistor. So I kept getting the 0 000 red led sequence, meaning the controller voltage was too low. So i took it out and voila. The motor purrrrrrrrrs.

Here is my setup:
