electrical help

[jefa]

have a 1986? (0A131197) 4 cyl. 50 hp merc outboard (brown band). diagrams in books do not quite match wiring. have 4 wires from stator, not six. two to rectifier and two to switch box. Cyl. 1 & 2 not firing. How do I diagnose if stator, switchbox or trigger? Diagram would be greatly appreciated and any advise would be most helpfull. Thanks, JEFA

Re: electrical help

^found resistance numbers for stator and they check ok, green to green/white ~600 , green or green/white to ground no continuity. Does anyone know of a test for the rectifier, trigger, and switchbox?
