All Testing Equipment Mounted
Today I mounted all the testing components; control box, controller, 48v lead acid, fuse and voltmeter onto the bike for a couple load runs. When I finished it was dark unluckily, so i attached a mini LED light and off I went. Only a short ride with the lead acids, But I am having problems changing the LVC and configuring the controller. About 20 mins on the non charged, 2008 lead acid 12ah batts.
When Moving all of it over I ran into a couple problems, as before I had the the single connectors for each hall wire. One of them must have lost contact or the wire had come loose because for all of the no load runs with it mounted in the bike, it had the really bad load knocking noise when I gave it throttle. So, My thoughts were " Oh, FU**...!!!" I thought I had connected the hall wires wrong and effed up the hall sensors in the motor!! ARG....... Luckily enough my brother convinced me to take out all the connectors and solder them for a secure connection. And voila, the motor Purrrred again! I then immediatly took it off the axle stands and took it for a little test drive. Acceleration is far better than expected, likewise with the torque. As this is the high speed motor, I expected little torque, especially up the hill where I live. Went up and down the street a couple times. Such fun. The motor was a lot quieter than in the testing and test video.

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.
