Emergency kill circuit ?

[Joker2]

Question for my nightmare troubleshooting problem, already lost 3 weeks with the boat, here goes: I have a 1994 150 HP Ocean Pro, I have no spark on motor, when I disconnect the 1 pin amphenol style connector on the black / yellow wire ( kill circuit ) back by the power pack the engine starts and runs fine. Changed kill switch and ignition switch, I get same results, is it possible that the power pack or the stator could be bad or is it definitely in the wiring of the kill circuit ? Thanks for the help.

try cranking the engine with that wire connected, but with the engine harness disconnected. Start out by running the engine like you had it with the black yellow wire disconnected, then after its warmed up and will start easy, hook the wire back up, disconnect the main wiring harness on the engine. Go to the starter solenoid, jump from the big red(battery cable) to the yellow red(it may take a jumper wire) and see if the engine will run, that will tell you if its the engine side, or the boat side. If it runs with that black yellow wire hooked up, but with the harness disconnected, the engine is OK. While its running, turn the ignition key to the run position, with the kill switch in the run position. Hook the harness back up, if the engine shuts down, there's something in the boat side that causing the trouble. Several things to check on the boat side if its the problem, make sure you have the wires on the key switch correct terminals, make sure you have an outboard key switch and not an I/O switch. Make sure your kill switch is for an outboard, if it has 4 terminals, make sure you have it hooked up to the no terminals

thanks I will try today, I just replaced the ignition switch and kill switch with OMC parts, thay are wired correct, I made sure. Thanks

OK today I went down and followed some tests given by CDI. First I checked spark. I have no spark on the Port side of motor, even with the black yellow wire ( kill circuit ) pulled apart. Explains why engine was starting but running bad ( only 3 cyl. ) Now I feel it is not the kill circuit. I pull the 6 wire plug on the starboard side going into the powerepack. Crank it , Port side now has spark. They say if you get spark back to go ahead and check bl/yw and bl/ orange for a short to grnd. Did that it was OK. Then to check to see if the shift interupter switch is located in the circuit where there is no spark. I can't find anything about the shift interupter switch in my SELOC book. Any thoughts ?

I thought the neutral switch only interrupted the starter solenoid and had nothing to do with the kill portion.

That's what I thought, but those bl / yw wires up by the power pack continue down the starboard side to some kind of switch that rests on top of one of the shift cable. can't find that switch ( if that's what it is ) on my diagram. You know what that is?
