My 1997 15 HP Mariner has no spark. Ran great last week. Yesterday when I tried to start it, there was no spark on both cylinders. I have a Mariner/Mercury service manual. Stator resistances checked out fine. But when I tried to check the trigger the manual stated to measure between the Brown/yellow and Brown wires. Only my engine has no Brown wire. It does have a Brown/White. The wiring diagrams in the book shown a Brown/yellow and Brown/white wires to the trigger. Can anyone confirm that the Brown/white and Brown/yellow are the two wires that the resistance measurements should be taken at? Or is there a solid Brown wire somewhere that I should look harder for? The reason I'm being so cautious is that the resistance between the Brown/yellow and Brown/white wires is about 750 ohms and the trigger resistance should be 6500-8500 ohms per the manual. If the Brrown/white wire is correct, then my trigger is bad. So I don't want to buy a new trigger if I'm measuring the wrong wires.
