Its never a bad idea to know exactly where ya stand with the battery any time theres an electrical issue, so, yea, check water level & charge.

Is the bike parked outside or under cover?

Switches probably last longer parked under some kind of cover, even just a car port,
start with a Volt meter, check power to the flasher unit. Hopefully, youre gettin power there & thats what failed. Get one from a junk yard for about nothin,, The OEM unit is stupid $$, probabvly a whoppin $7.50 at Auto Zone,,

Of course connectors need looked at. Check easy stuff before ya go diggin in the switch.

You stop, got the clutch lever pulled in & it dies? Even if youre tryin to give it gas & keep it alive?

little details, how its acting, stuff no one can see or hear but you, these are important,, any work just done? hows the gas? old? just start this mess? been parked? details, things you know that we dont,, the more blanks you fill in, the more likely these guys are to get you goin quickly,.
