Hi, I have a 71 Johnson 125 I just rebuilt. I first tested it to see see if I had spark while just crank, and I did not. After troubleshooting I found that the pulse pack was bad. I got a new pulse pack from cdi, I removed the clipper circuit and I now have spark.
So so I decide to try starting it with muffs just to be sure it will start when I get the boat in the water. The Engine would not fire until I released the starter switch, it would just fire once. It also would fire once when I turned the off. I can actually hear the spark every time I turn the key off.
I found a post post here where it says to put a diode from the starter side of the relay to the pulse pack wire on the terminal strip. I did that, and it will only fire with the starter going, it kicks of the flywheel once it starts. When I let go of the key it dies. I put a jumper wire from the red wire to purple on the terminal strip and it fires right up and idles good, just need to disconnect the battery to shut it off.
I have a new battery. With the key on I have 12.5v at the red wire and 11.5 at the pulse pack. Any one have any ideas. Thanks.
