Re: 1983 mariner 90 inline 6 cyl.
A bad stator would effect all cyls. that share a common switch box (odd or even number cyls.) A bad trigger would effect 1 and 2 or 3 and 4 or 5 and 6 so that leaves 2 things a shorted rectifier ( disconnect the 2 yellow wires from it and ck for spark) or a bad switch box
