Hey guys I just picked up an SLH and it seems to have a problem with the switches on the left side of the handlebars. It needs the lanyard in to start it, but after it is running, the stop button, trim, or bilge pump will not do anything. We checked the trim switch so far and it seems to be working fine(as a switch, electrically). could this be a problem in the electrical box or corroded wires or what? any help is greatly appreciated. thanks
