Honda 2004 BF50 A (carburated model) is shorting the 15A fuse as soon as I turn the key switch to the on position. Its off the boat and on a stand. I had it hooked to a battery jump pack for power and was warming it up to change the oil when I tripped on the cables. The positive and negative cable on the jump pack probably touched but not for long (positive jumper clip came off) and the remote control box hit the ground. I set it back up and now every time I turn the key switch on it blows a 15A fuse. Power trim still works (key switch does not have to be in the on position for this). I have also jumped directly to the starter and the engine cranks, fires, and runs great. Some forum suggested that the momentary battery cable contact may have shorted the rectifier so I replaced that but I still have the same problem. Ideas? Thanks in advance
