Yamaha T50 2003

No power at the keyswitch. No power at the trim. Accessories work. Today I committed the ultimate sin. I have been boating for 60 years but I will own up to this one. I had to disconnect and switch batteries while the motor was running and I reversed the polarity. I still can’t believe it. Kind of just caught me off guard and took me a couple seconds to realize what was going on. The boat continued to run but it looks like i fried the gauges. They have power but read wrong. After shutting down there is no power at the key and trim. I checked the fuses at the battery switch Is there a main fuse under the engine cowl? Any help is appreciated. And yes the tether is correct.
