Hi Mickle, did you by any chance connect the battery the wrong way round, i.e. plus lead the negative pole and negative lead to plus pole?

Hi Mickle, When you connected the new CB did you reconnect the thermal cutout and thermistor cables correctly? The thermal cutout has two orange wires, and connects to pins 4 and 5 on X6 (on X6 there is provision for pin 3 but it is not fitted). The thermistor has grey/purple wires, and is connected to pins 1 and 2 on X6. Last question for the moment. Do you have a multimeter? Cheers. Karl.

Hi Mickle, without a multimeter, or someone who has a multimeter, it will be next to impossible to check out the circuit. The only other thing you can do is to remove the pod and send it to someone who can check it out for you. Seeing as I live in Germany it's a bit impractical to send it to me. This can eliminate the pod if it's working, but items such as the thermistor, thermal cutout, motor switch. cables etc, could be the problem. Cheers. Karl.
