"On my BF30A, I reversed the connection on the battery hookup and fried what I assume is the ground wire going between the stern bracket and the motor shaft. Hopefully, that's all. I have been able to disconnect the fried wire on the motor shaft and am in need of advice on how to go about getting to the screw head on the stern bracket. Do you think I screwed up anything else, other than frying the wire? Any help would be appreciated including where to buy wire and possible part number. Thanks much."
