Ignition troubles
I noticed while checking my motor with it running that when I pull the plug wire from # 3 and # 6 that there is no noticable difference in the running of the motor. All other cyl. make a big difference. I am using the Merc maint manual for trouble shooting and everything seems to check out just fine. I bought this motor about three years ago and dont notice it running rougher now then when I bought it. I have two switch boxes and #3 is the bottom output on the top switch while #6 is the bottom output on the bottom switch.
I do get a little spark from the plugs but not like the others. I have moved #3 plug and wire up to #2 position with the same results which tells me that the plug and wire are good. I also moved the trigger signal from #1 to #3 and swapped the plug wire to keep the firing sequence correct. Then #1 along with #3 is not firing. So it sounds to me like my trigger to 3 & 6 are bad along with something else on #3. Long story short after looking some more while running it dies altogether, I was able to restart it but now it is missing really bad below 1500 but clears up a little above 1500. Shut it down to check more connections and now no fire at all. Where to go from here, do all the ohms checks again and write down the readings, replace the stator and trigger. Any suggestions with in reason will be considered. Turbo

Rechecked my readings today and one of stator coils is open and the other is real high. Looks like a stator is going to be in order.
Another question, while I'm at it should I replace the trigger since I will be right there? Should I go with CDI parts or Merc. Is one better then the other? Thanks for the replies, Turbo

RAPAIR is the reccomended brand by most. IIRC RAPAIR is made by CDI as well.
