Fan Motor

If the fan starts when you spin it by hand, that pretty much rules out everything but the fan motor. These are series wound brush type motors. What generally happenes is that a wire breaks on the armature , effectively reducing the number of functioning poles. I have fixed them, but on a new bike, you will want to ask for a replacement. It could possibly be low voltage, but I bet not. The voltage is easy to check with a meter. Should be 12 v DC. If there are multiple breaks, the fan can still run but it will run at a reduced speed.
