Engine wont shut down!!!!!

[fish2day]

My engine will not shut off when you turn the ignition off, and the Tach stopped working. it slows down an finally boggs out, but does not shut down immediately. Does this sound like the ground?? Advice appreciated.

It might help to know what model you are working on, model number?

Oops, My Bad, I can't believe I did that . 1991 johnson 200hp J200TXEIB.

I had a problem with my ignition wires inside the cowel, the ignition switch stop working the last time out. I replaced the connectors on two of the wires and now the ignition switch os working again, just not shutting enginr down. I was thinking it may be a ground problem, and wanted other opinions.

Re: Engine wont shut down!!!!!

In order to shut it down the ignition switch grounds the black wire with a yellow tracer going to the power pack. Check that circut and see if it goes to ground with the key off.

I know the wire you are speaking of. What will be wrong if it is or isnt grounded?? Thanks

Re: Engine wont shut down!!!!!

It has to ground the pack to shut the engine off. If you disconnect it at the pack, and use an ohm meter, the wire should go to ground through the ignition switch. If it doesn't, you need to check the wiring all the way back to the ground on the engine. If the system is grounded with the key in the off position, you have a defective power pack, not grounding properly. If your engine is the type that has a ground strap from the power pack, make sure the terminal is clean and tight.

Thanks for your help, I'll post my findings tomorrow and maybe it will help someone else.

Yes, let us know what you find.

wow, duplicate problems on very similar engines... maybe between the 2 of us we can figure this out wIth Daviet's help.

Re: Engine wont shut down!!!!!

I did some trouble shooting and here are my results. The black/yellow grd wire going to the power pack is grounding when turning off ignition switch. There are two of them and both are grounding. I do have a strap ground that mounts on the top of the powerpack and I cleaned it. The grey signal wire for the tach was disconnected inside the powerpack, I guess that is why the tach wasn.t working. Now, some recent history on my engine: My Regulator/Rectifier shorted out last month and caught the powerpack on fire. Thr fire burned the ends of the wires off that connects to the terminal block on the Regulator/Rectifier.
I replaced the Timerbase, Stator, Regulator/ Rectifier, and Powerpack. Everyting was plug and play except for the wires going from the harness to the terminal block under the powerpack.
Now, my question is: If it was wired incorrectly would that cause the shutdown problem, or have I definately got a bad powerpack that was just replaced?? I have a factory manual and wiring diagram, and are going to trace all wiring again from the harness to the top of the engine where everything connects. Please verify if you think the powerpack I replaced id bad because of the grd not shutting engine down. All wiring from the ignition switch back the harness connection at the engine appears to be ok.

Re: Engine wont shut down!!!!!

You have one powerpack per side, it seems odd that both power packs would loose their internal grounds at the same time. I need to see if I have a manual on your engine and look at the wiring schematic to try and figure it out.

My engine only has one powerpack unit. Do you mean that it has two built in one unit? One for each 3 cylinders? It does have two grounds coming out of it. I'm hoping that its a wiring issue and not the powerpack.
Would the engine ground cause this ? or the ground from the ignition?

Re: Engine wont shut down!!!!!

Sorry, not thinking correctly. With only one power pack if the grounds are clean and tight, and the black/yellow wire shows a good ground back through the ignition switch with the key in the off position, it sounds like you have a bad power pack.

Re: Engine wont shut down!!!!!

I only unplugged the grd from the power pack and used a ohm meter by touching the block or powerhead. Does that not check it through the ignition??

 

[Daviet]

Re: Engine wont shut down!!!!!

To check the ground circut you unplug the black/yellow wire at the pack. Connect one leed of your tester to the black/yellow wire going back through the wire harness, not going to the power pack. Connect the other end of your tester to one of the ground wires where it attaches to the block. With the key in the off position you should have a complete circut.

Re: Engine wont shut down!!!!!

I did exactly what you said but I didnt connect to a grd wire going back to the block, I just touched the block itself. Is that not correct? I have a grd wire going to the stop switch that is located underneath the powerhead next to the shift cables, and that wire is open, not grounded

Re: Engine wont shut down!!!!!

Touching the block should be ok as long as you make a good connection. I am going to have to see if I have a manual on your engine and look at the wiring schematic and see about the grounds.

After doing more research on my engine today, I cannot get to shut down without choking it. The engine is running good and firing on all cylinders. It starts as soon as I turn the ignition switch.
The only question I have is the wiring coning out of the powerpack. I attached the schematic for you to view.
I have a yellow wire with a red stripe coming from the harness and one coming from the powerpack. The one coming from the powerpack has a male bullet connector on it.
The schematic shows them running together and then attaching to the solenoid. Whenever I attach them together on the solenoid the ignition will not spin the starter. When I disconnect them and leave the one coming from the powerpack disconnected, it starts ok.
Can you tell me where the yellow/red stripe wire coming from the powerpack goes?? and could this be my problem?? I do not want to purchase a powerpack until I'm sure, because I have read that other people have replaced the powerpack and had the some problem.
I have tested my ignition switch and grd wires at the powerpack and all appears to be grounding. Thanks for your help.
