Got a beta evo 300 16 model, fan is only working intermittently, I’ve overrided the thermostat, wiggling the wires seems to affect the fan speed, also the headlight wire and connector block is getting very hot

 The problem is the switch, etc. Remove the headlight and all excess wiring. 

Disconnected the light and bingo it works, also tried a headlight with a working build and it also works with that on

The first thing I did when I bought my present bike. I really hate redundant parts (and especially wiring) on any competition bike or car. I got rid of the placebo switch at the same time and left it on "wet" setting.
