[naladog]

I have a 1980-81 inline six mercury outboard that has always been a hard starter, but have now lost spark in cyl 1,3,5 moved a trigger lead off of #2 coil and put it on #1 and #1 started sparking so is it my trigger or my stator or my switch box not sure how to tell please need help my mechnic has come up short.

Re: no spark

Trigger wires need to be moved in pairs.... If you have lost spark on odd cylinders, then it's probably a switch box... but you need to investigate further to be sure...

Re: no spark

Heres CDIs test

If you don't have a OHM meter you can check your problem by swapping the red and red/white and the blue and the blue/whhite wires at the switch boxes, it the spark moves to the other 3 cyls then it is the stator and if it stays the same it's the box.
