Effectivememnte Raul, as several have answered you is correct, although not all electrical systems are the same. I have Chevy but without that problem. In another car I had if I grab experience in cooling systems. Locate and unscrew the bulb that makes the fan start. Check it and it is almost certainly covered with tartar or calcium deposits that make the heat transmission and starter order fail. You can clean it by sanding it, but it is so cheap that it is best changed. Czech when buying it that is the same temperature range in degrees Farenheit. I hope my comment serves you. Already in the desperate case see the electric and check the motorcycle maker, not forgetting to check the electrical connection harnes of the same.
