Hello. My name is Tan.
Could I get the engine serial number please?
Does the engine crank over spin the flywheel?
Ok locate the switch box # ***** and disconnect the black/yellow wire. Now check for spark. Do you have spark?http://www.marineengine.com/parts/mercury_marine_parts/static/img/COMMON/19696.gif
We want the black/yellow from the engine harness that connects to the switch box. Not the black/yellow coming from under the flywheel.
