Honda fuse#32, 50amp were is it?

No start after, Thermostat change

Hi usually in with the engine in big box.

Year, model, sub model and a short description of the problem would be nice for anybody like to help you.

"No start after, Thermostat change" meant very very little information to go by and I do not want to give you my wrong guess. But 50A is a bigger fuse or fusible link and it's normally in the under hood fuse relay box. Update the information so I can give you the diagram for the vehicle.
