Ran good, bad CD ?

[2fastroy]

87, 85hp force, went boating, parked it next morning it would not start. It ran fine till i turned it off. Took it in to get fixed and he says I need 2 new cd modules. I,m confused because it ran fine, does both cd going out when you turn off the motor sound right?:

No. Check to see if the safety switch lanyard is installed properly. If so, check that the two white wires on the engine terminal strip are NOT grounded when the key is turned on. Grounding the white wires shuts down the ignition and turns off the engine.

Yeah! too much coincidence for two packs to go bad at the same time. More likely the ignition switch. Remove blue wire either from switch or at engine terminal and see if engine starts. If it does, the switch needs to be replaced. To stop engine replace blue wire or jumper white wire to blue or ground terminal.

I tryed the lanyard, the 2 white wires on the terminal were not grounded, and disconected the blue wire on the ignition. Nothing changed. So, I went with the mechanics advice and switched both CD modules. Still nothiing has changed. The motor will turn over but will not fire, no spark. Remember it ran fine until i parked it for the night. Please help. Thanks Troy:

There's a 'stop' wire from the cd, to main junction strip. (mine are black w/gold) maybe white on yours... Disconnect them both from the strip and try. If it fires then there's a problem on the 'boat' side, not 'engine' side.

well, what was the issue?

Re: Ran good, bad CD ?

Could the stator possibly have gone out? Maybe it's not getting stator voltage anymore. The blue and yellow wires coming from the stator to the cd modules should be producing 100 volts each I think. Could be wrong on this because I don't have my manual in front of me, but I have a slight recollection of high AC voltage through these wires.
