2012 Sea-Doo GTX 155 No power, no display, no response

I need some help to point me in the right direction. I just bought this ski yesterday. When I got it home, i could hit start button and it would wake up and even crank over and run. I do have other problems like IBR not working. But like I said yesterday it would at least wake up and run. I noticed the fuse box in the back by battery looked like it had been wet and had corrosion, so today I pulled positive wire off battery and pulled all fuses, and rails and cleaned it real good with electrical cleaner and air. Put it all back together carefully and triple checked all fuses and wires etc. But I get no response when I push start and have lanyard in place. No beeps, no display, no nothing. Obviously it sounds like fuse box related, but I am curious if the ECU could cause this if it was bad. Does the start button look to the ECU to wake up ski or would it wake up even with bad ECU. Please help me understand what might have happened. Thanks

Relay inside the fuse box needs to be checked or replaced
