Having an issue with an inline fuse blowing instantly and with the ignition switch in the off position. Boat was running well the day before, then we had a bunch of rain that night, and next morning the boat would not turn at all. The fuse is a 5 amp fuse on a red wire coming off of the ignition breaker which is then connected by a jumper wire from the breaker to the battery terminal on the ignition switch. I have power and all other accessories are functioning properly. Ignition switch and breaker do not appear to be the issue based on testing. Is the issue most likely a wire short? Could the starter solenoid or starter motor or other component be causing the issue even with the switch in the off position? Tracing the wire for a short seems like a daunting task, so would be good to know if there are other components to test to rule out. Thank you for any advice.
