I checked the 50amp fuse along with all the other fuses in the box between the seats and they were all good. Is that the ones you are refering to?There is a 50 AMP main fuse AND a 15 AMP Ignition fuse that are tired together. I am assuming you blew the 50 AMP main as it is inline before anything else. BUT check both of them.
I was going to try the hard reset suggested by 1SINNER and see what happens.I apologize......... I am not by the machine to go look. But the wiring looks like Honda may have put a diode inline with the battery cable? A lot of companies put a reverse bias diode inline as a fail safe along with a fuse. I will look later today.
BUT as mentioned above it is a good idea to "short out" the PCM to allow for a reset. It won't hurt anything to try.
