I reversed the battery cables on my 2005 60 hp mercury 4 stroke. After switching them back it keeps blowing a 20amp fuse when I try starting it. Any suggestions as to what I should be looking for?
Did the same thing. Burnt all the insulation off the wire that goes from the alternator to the starting relay. Had to mend the whole wiring harness and install a new wire fromt he alt to the relay.
