I have a 1998 Chaparral, 4.3 Mercruiser that no voltage to the ignition coil. There is continuity through the purple wire to the ignition control module, the alternator and oil pressure switch. There is no continuity to the ignition switch (which has 12v to the purple line when in 'Run' position.
If we jumper 12v from battery to ignition coil when we start the boat it runs without issue. My assumption is there is a corroded or bad connection in one of the wire plugs between the dash and the engine.
Does the lanyard switch only interrupt the ignition wire? If the lanyard was faulty would the boat run with our 12v jumper being applied to the ignition coil?
I believe we just need to trace the ignition wire from the engine to the dash and find where we are losing continuity but would love to hear other opinions. Thanks in advance.
