1998 ps 190 everything works well except when I turn on the courtesy lights. Boat is new to me and I noticed that win I turn on courtesy lights, (factory installed), the tach reading drops significantly. Ideas? Haven't looked into it yet..tach signal should not be tapped for 12v from factory, correct? Anyone got a schematic for this boat? Thanks, Bratcop.
