Hey guys and gals im new to the boating world this is actually my first boat of my own, its a 1978 CENTURY closed bow Classic and the inboard motor was swapped for a 1979 Evinrude 200940A 200hp outboard. The problem im having is the motor well not turn off with the key, when I turn the key off i can hear one side shut down so i know one power pack is turning off when i jumped the black /yellow strip wire wich shuts the power pack down over to the other pack with a jumper cable and shut it down still only one side shuts down. Now if i take the jumper to a ground and to the black/yellow stripe wire on one side it shuts it down complelty. So im a little puzzled here and have no idea what to do next .. any help would be appreciated. Thanks
