09 230SX starter cut-out issues

[Sjetter]

Might be coincidental but shortly after interrogation with YDS my starboard eng starting was intermittent. Hear the click but no crank, if it did crank I would get ignition and start, but would not shut off when key placed to off. Had to shut down with battery selector or starter would continue to motor. Tried swapping to a known good ignition switch, no help. Replaced starter relay, work great for about 20 starts on and off. After the 20 starts, eng will start but will not shut off will key to off, starter still motors, again requires battery to off to shut off. Tried grounding the white wire at the starboard disconnect to see if that would stop the starter, no joy. Starter relay appears to be doing it's job, cranks and starts but whatever tells the starter to stop motoring in the "on" and "off" key position is not working. May be wiring, short to ground, damaged/kinked wire or the ECU. At any rate I'm pulling it out of the water to bring home and troubleshoot to check condition of ECU and wiring inside fuse box. Or swap ECU's while I'm at it to see if the problem follows. If anyone has had this problem, any info would be greatly appreciated

Not sure if this helps but did you replace the jumper connector after you disconnected the YDS cable?

 

[Sjetter]

Yes I checked the pins and wiring at that connector also all good

I believe the starter (relay / solenoid) receives the signal to provide power to the starter from the ECU which receives signal from the key switch and checks the clean out hatch and throttle position switches before engaging the starter.

I think that swapping ECUs is a good next step in your diagnosis.

You may also want to check the lanyard switch. When the clip is pulled out I belive it puts a ground on the ignition ckt to kill the motor.

Another item to check are the modular connectors behind the 6 inch circular hatch in the rear starboard locker. (Same place your YDS connector is located). I had one that had water in it last summer that was the reverse od your situation. I could start the motor but as soon as I released the key the motor would stop. Pull all your connectors apart in that compartment.

 

[Sjetter]

I pulled the clip and tried to start with the same result starter still motored with the key off. I guess the 1/2 of the switch that goes to starboard could be bad. I will pull that and put a meter on it. I have checked all connectors and wiring behind starboard cover, all looked good so far. I currently have the just starboard fuse box pulled and did find a severely kinked red wire in one of the bundle feeding into the box. I'm trying to identify that wire see if it ties in somehow to my problem. I will probably wind up swapping ECU's eventually. I just keep going back to the fact that my new starter relay worked as advertised for several starts after replacement. The problem started after tubing, skiing, rough water, quick throttle applications etc. maybe affecting a damaged wire. I found the starter relay continuity check per the service manual and my old relay checked good. Removing and replacing the fuse box to replace the relay may have temporarily fixed a wiring problem until I hit rough water and shorted something to ground or opened up a circuit.

 

[Sjetter]

Do you happen to know if the lanyard switch will pull up through the console after loosening the jam nut or do you have to access the connections from underneath? Scratch that, dumb question. The switch is bigger than the hole....duh

 

[Sjetter]

Well I swapped ECU's problem did not fix or follow. Taking a break from heat and going to try starter relays while I have both boxes out

 

[Speedling]

Or check connection on starter itself. Mine was loose when i bought it and i chased it a bit. I also had the relay bad at same time.

 

[Sjetter]

I swapped ECU's and starter relays neither fixed the problem or followed to the other eng. Both eng's will crank and start. When I go to off ignition stops on the starboard eng but starter continues to motor. ECU and/or relay not the problem. I thought it would have been something in the ECU affecting starter cut out. I need to find out what tells the starter cut-out circuit to open and stop the starter motoring.

 

[Sjetter]

I did have a loose positive cable last week before I started removing the ECU/relay boxes. It would move from side to side. Removed the starter and tightened, no joy. Negative was secure

 

[Sjetter]

Maybe my starter is fried. I guess I will go ahead and try swapping starters while I'm at it. Done for now, have to work tonight. Will try tomorrow

Not sure if there is a selonoid on the starter motor as I think the starter relay performs that function. When I found my wet modular connection, I haD to reach deep down in the compartment to find it. It really did not pull through the access port.

That is correct. The relay attached to the ECU provides the solenoid functionality.

I'm not sure how our starter system operates. But it does Sound like a stuck starter solenoid. Should be easy to test if you have the starter in hand. Getting it out will probably be the tough part.

Edit: you should be able to tell with the YDS when the ECU is triggering the starter. So if the YDS shows no start attempt but the starter is still spinning, I would imagine it's in the starter.

 

[Sjetter]

My connectors fortunately are right behind the access plate and high and dry. I did spray with contact cleaner while I was there. Removing the starter is not too bad 2 bolts to remove and then pry from the front with a long prybar or screwdriver straight back. If swapping starters doesn't work then it's YDS and chasing wires. That's about all that is left

On my 07 SX230 I had a lanyard switch issue. I was able to access the lanyard switch connectors by removing the speaker at the drivers feet. If you disconnect the connectors you will isolate the lanyard switch. The switch is a normally an open contact and when activated it is a closed to prevent the motor from starting.

 

[Sjetter]

Man I wish I had a speaker there but unfortunately I don't. I was looking at that yesterday trying to figure out how to access that. I didn't really see a way to get to the terminals. I was looking at that very thing that the wire or side of that switch that feeds the starboard eng may very well be faulty. Did you have the problem that I have where the starter would continue to motor with the key switch off?

 

[Sjetter]

Well swapped starters as well, no help......help! Lol That would be all of the big items in the start system. After getting a nap from work last night I guess I will visit my Yamaha dealership and try picking a tech's brain. Thanks in advance for any other suggestions!

 

[Speedling]

I didn't read it all but did you test swapping ignition switches?
If in the switch all the other components would work fine but signal to them doesn't stop.
