    Angry No Spark in 1987 Cobra OMC 3.o 4cyl

    I just replaced the coil and am not getting a spark at the plug wires. The coil is getting 12v at both the positive and negitive sides but only 6.5v out the coil. Any ideas?

    Don't want to pi$$ you off But did you put the rotor back on? Do you have spark at the points? Is the wire from the coil to the dis ok .
    I have a 1985 3.0 and just went through the same thing. On mine the wire from coil to points was grounding ouit where it enters the dist.

    Why did you replace the coil? Was it for this problem? Have you cleaned and checked the points to make sure they are making contact and opening and closing as the dist goes around?

    purple gray goes on positive side and black wire to diz goes on negative side. Check your fuses.

    Sounds like the case of "I forgot the Rotor"?

    We have all done stupid things in the past.

    And, laughing at them is good for the soul.
