I have a 1989 Mercury 40hp (4 cyl) (S# 0C168700)outboard that will not start. It does not seem to spark. It ran last fall, this spring it will not run. The only change is a new starting battery. <br /><br />If I pull a plug and look for spark against the block there is nothing. All 4 plugs have good spark if I test them on the push mower.<br /><br />The coils seem ok. (short between +/- terminals and between coil tower and either +/- it is open). <br /><br />The trigger vslues are 800 ohms between brown and white/black trigger leads as well 800 ohms between White and Violet trigger leads<br /><br />The stator readings worry me. I have open between Blue and Blue/white and 135ohms between red and red/white. What are the correct readings for the stator? Also is it possible for the stator to just stop working over winter? <br /><br />Once again, the only change from last fall when it work and this spring is a new starting battery.
