Hi guys. I recently pulled new cables through for a new fishfinder and 2 throttle/shift cables. Every since I pulled these cables through my wouldn't start. I sounds like it would when a battery is going dead when I turn the key. So I charged both batteries and still had the same problem. Next I saw that I have a two negative cables on the negative side of my battery. One coming from the engine one wire that splits of in two direction. The wire splits off to the trim tab power box and the other splits off to an unknown location toward the circuit breakers at the dash panel of my boat. The reason I'm saying all this is because when I disconnect the cable that splits in two the motor cranks right up. When I put it back on the battery it seem like it shorts out the battery preventing the motor from starting. The cable that splits in two runs the same route as the cables from the throttle and fishfinder. Before I ran the new wires everything was working perfectly. Sorry for the long post. Does anyone have any thoughts on this? I will include pics tomorrow if it would help!
