I have a 1994 Sea Ray with a 100 hp Mercury O/B.<br />I recently replaced the ignition switch. The old switch was for a Omc motor. I replaced it with a switch for Mercury engines.<br />Now my instrument gauges wont work. The fuel, depth finder and temperature gauges only. My speedo and tach are fine. I thought I hooked it up to the same I.D. numbers. From the B on the switch a wire goes to the gauges, should these go to a different letter? The switch has off, on and start with push in choke. It has letters A,M,B,M,I,S,A going clockwise and C in the center.If no suggestions is there any other way to hook up the gauges.<br />Thanks.
