Sounds to me like a short somewhere... I'd start in the vicinity of the ignition switch...

new flasher didnt help.........had electrition troubleshoot wire harness,, no problems... left key on, a week later put tractor back togather, found key on and battery dead.
charged "witch took days" and started, most guages worked but tach was freaky, flasher worked but one side was bright and flashed normal and the other dim and flased fast.
volt meter said it was still weak so removed cowling and disconnected battery to charge, found battery installed backwards.
turned battery around and reconnected, started good but no guages work and flasher dont work.
oops..
now i dont know if the original problem was just a dead battery or the guage unit that controls the voltage to everything.
but i did install the battery backwards "embarrasing"
i cant belive the thing started after charging it backwards.
