Re: Boat wont beep or do anything from the key?
Scar, I'm slightly confused from your last post, but I think I understand. The ignition switch has 3 positions: off, ignition, start. What you describe as a quarter turn (it should be more like an eighth turn) is ignition. This position energizes the coil, your alternator, your gauges and the "beep" with 12 volts. The beep is a safety device to alert you that the engine temp and/or oil pressure is low (oil pressure is zero until the engine is turning over). The half turn (should be more like a quarter turn or less) energizes the starter solenoid with 12 volts and closes the contacts so high amperature can flow to the starter. Since you have a volt meter, turn the key to ignition (first position), place the red lead on the ignition switch screw terminal labeled "I" and the black lead on a common ground (or if unsure of the ground,run a wire all the way to the battery negative terminal and touch the black lead to that. You should have at least 12 volts. Post back what you find and we'll take it from there.
