I have a question we were out the other day for the weekend and the next day when i went to start the eng it wouldnt start.. Used the emergence start button and it started right up. ran great after that. when i stopped the boat after awhile the power started fading witht the lights in the cabin and the anchor .. started the geny and everything worked. The boat alarm came on and said [h=2]r starboard engine diagnostic failure or alarm and it beebed till i let it warm up and charge for a bit then worked great till i turned off the boat engines again.. I took the batterys to get checked thinking it was them and they said they were fine. So not sure what it is.. Thought it might be the alernator but not sure.. Others thing it is a ground wire etc.. when i am shore power everything work great as well.. Any help would be great thanks....[/h]
 
Also check for corrosion up inside the cables. They might look fine but the current flow could be obstructed. Happened to me.
