Re: evinrude 225 wont turn off

disconnected ground wire coming from shift switch motor does not start with black/yellow wire connected ground wire has no affect one way or another if b/y wire disconnected motor runs fine when touched it kills the motor completely now. b/y wire cut on motor side by red plug

Re: evinrude 225 wont turn off

I don't know how we got from "the boat starts and runs fine but when you cut the ignition switch off the motor continues to run " to " does not start with black/yellow wire connected "
When you cut the blk/yel wire at the engine plug and touched it to ground, you simulated the key switch being turned off or the lanyard being pulled off the kill switch. The engine should shut off, and it did. With the blk/yel wire connected it will not start, indicating that the blak/yel wire is constantly shorted to ground somewhere ahead of where you cut the wire. You need to get a multimeter and perform the check that ezeke recommended in post #19. For now, you can leave the ground for the shift interrupt switch off. That will take the shift interrupt switch out of the equation, until you can get it to start.

Re: evinrude 225 wont turn off

before i found a bad plug by power pack coming from shift switch motor ran on 3 cyls with b/y wire connected, without the b/ywire connected the motor has cranked and ran on all 6 cyls checked key switch and lanyard with meter everything ok there problem seems to be at the power pack

We can't help you if we don't know what you've checked, what you found, and what you fixed. Where are we NOW! With everything back together does it start? If it does, answer the four questions I listed.
If it won't start, are any cylinders firing? It will be difficult to start if only one bank is firing. If it won't start with the blk/yel wire connected, then the black and yellow wire is constantly shorted to ground. If that is the case, you need to find the short. If you cut the blk/yel wire at the red plug and it started, then the short is forward of that.

Re: evinrude 225 wont turn off

when i bought the boat the b/y wire was cut at red plug it would crank and run on all 6 cyls , when you touched the b/y wire together it would only run on the 3 starboard cyls , i found a bad connector coming from shift switch i cut and spliced that together , with shift switch ground disconnected key or lanyard switches does not kill engine , as of now without the b/y wire connected the motor starts off key switch and runs on all 6 cyls when b/y wire is touched together it kills the motor instantly put meter on key and lanyard switch checked out ok i have not checked b/y wire from key switch to red plug yet , i found two b/y wires at power pack 1 has continunity the other one does not

Re: evinrude 225 wont turn off

I sent you some info Via email.
One thing at a time. when you connect the blk/yel wire you cut, it is finding a path to ground which kills the engine. You need to find that and fix that first. The short has to be ahead of where you cut the wire. If it was shorted in the engine harness, it wouldn't run at all.

OK. You've made some progress. The engine was continuing to run on the three starboard cylinders because you had an open circuit due to the broken connector on the stbd side of the powerpack. You fixed that, so now when you touch both ends of the cut blk/yel wire together both powerpacks are shut down (Like it should do when you turn the key switch off). Now you need to find the short that is causing the engine to shut off when it shouldn't.

The blk/yellow wire is shorted to ground somewhere ahead of where the wire is cut. Read the info I e-mailed to you and see if you can find the cause of the short. The problem is somewhere between the big red plug and the Ignition and kill switches so focus your attention on that. Did you pull the red plug apart and look inside. I had one harness that must have gotten moisture in it and it shorted from one of the pins to the ground pin. It burned the plastic to charcoal, making a permanent path between the two pins.

Don't worry about the lack of continuity from the stbd blk/yel powerpack wire. If you were trying to read through the diode and didn't have the meter + lead on the correct end of the wire, the diode was blocking the current and giving you an open circuit indication.

Re: evinrude 225 wont turn off

should there be current going thru black/yellow wire i got shocked by it by the red plug coming from key switch

Re: evinrude 225 wont turn off

Yes, it will shock you.
When key is in the on position, the black/yel wire kill circuit is normally "floating" electrically.
It is not electrically connected to anything except the powerpacks at the engine end.
When you turn the key to off, the kill circuit gets connected to ground internally to the switch.
That is proper normal operation.

Re: evinrude 225 wont turn off

i found the problem after a lot of help from greg (thanks again) i had two bad pin connectors at the power pack the one going to the shift switch and the main black/yellow wire from the red plug coming into the power pack i also had a bad connection at the red plug with the black/yellow wire and had to run a new wire from key switch to past red plug and connect it to b/y wire if anyone has these similar problems check the pin connectors in and around the power pack it took me almost a week to find out what the problem was
