1988 - 25HP - No spark to lower cylinder

[KIGuy52]

The lower cylinder spark plug's not firing.<br />This happened suddenly while I was trolling.<br />Plug and wire are good. Is there a way I can<br />test the electrical components to narrow the problem down so I don't buy a bunch of unnecessary parts? I've removed the flywheel. Nothing obvious under there. All the wiring, etc. is good and tight.<br />Thanks for your help,<br />JD

You can exchange the power wires to the coils, if the problem changes cyls. its the switch box and if it stays the same it's the coil
