Hi. I have 140 HP 3.0L Mercruiser and I only get spark when I run a wire from positive terminal of coil to a positive wire somewhere on engine e.g starter motor or solenoid. Motor starts fine then, and I undo wire and all is Ok till I next need to start. I am sure it is something simple but can't work it out.
Any sugeestions? Thanks.
