Just got this and it’s in really good shape for the year but the oil temp light comes on as soon as I turn the key on and doesn’t turn off any ideas where to start will be appreciated

I can think of three things it could be , a bad sensor , a bad alarm box ( next to the cdi ) which controls the temp light or a wiring problem ---I think I would disconnect the temp sensor and see if the light goes out , if it does , I would think it could be a wiring short
