Yamaha kodiak 450 why does brake indicated light flash

Under seat

fuel filter is in the petcock where you turn the gas on and off

apply 12volts directly to the fan, if it does not work, replace the fan, if it works then replace the temperature sensor, good luck

Hi Brian, get a digital volt meter and start the ATV measure the voltage at the battery or at the alternator it should read around 14 volts when charging, if it reads 12 volts the charging system is not working, check or a blown fuse or broken wire, if you can access the alternator directly measure at that point. It takes 14 volt output from the alternator to charge a 12 volt battery

its either the voltage regulator (most likely) or the stator. you'll need a service manual to check the stator output.

turn the idle down? choke could be stuck too.

Check your fuses.

Does this unit have disc or drum brakes?

Always assemble your engine at TDC on the compression stroke...
