Customer Question
Hi I have a...

Hi I have a 1996 Suzuki DT140. engine fires up perfectly. When I bought it, owner had just performed routine maintenance. Oil level is correct. No fuel leaks. My issue is when I start it; it’ll will shut off 15 seconds after. As if someone turned the key off. It can be cranked right back on without delay. First turn key. But count 15 seconds and it will cut off again. (No jogging; like i said. As if someone cut the key off)

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Is there anything else the Marine Mechanic should be aware of?

No that’s it.

Is the idle speed adjustment knob you’re talking about not n the power pack case? Mine does not have that
Customer reply replied 7 months ago
It has a plug in the oil rest hole and where the idle switch would go it is closed there was never a switch there
Marine Mechanic: Matthew John, Marine Mechanic replied 7 months ago

Ok, Thanks! I will check to see if I have information on the correct model and get back to you if I can get hold of anything.

Matt

Hi there, were you able to check the Throttle Valve Switch by following the test procedure I provided?

Ask Your Own Boat Question
Customer reply replied 7 months ago
No wasn’t sure that pertained to my engine since the other one did not.
Marine Mechanic: Matthew John, Marine Mechanic replied 7 months ago

Yes, I understand. I thought the same thing. The only manual I have managed to access is the DT115-DT140.

If you are able to do the check on that TVS we can eliminate it OR wiring, connections or CDI unit.

Regards,

Matt

okay. I already had eliminated all wiring to the ignition and kill switch to eliminate possibility of one of those being a failure. I started engine manually and same issues.
Marine Mechanic: Matthew John, Marine Mechanic replied 7 months ago

Ok, great! The symptom that you are experiencing points to the Throttle Valve Switch. I have provided this test in an attachment. Please let me know if you require further assistance in the test procedure or locating the TVS as the pic in the attachment may be not the best.

Regards,

Matt

Ok. My sensor is a 2 wire

Customer reply replied 7 months ago
Not sure if this matters. My buzzer never sounds. I replaced it because it was bad. I tested the new one and it’s working manually. But when turning the key to acc or to crank. It never sounds.
Marine Mechanic: Matthew John, Marine Mechanic replied 7 months ago

Hi, sorry for the late reply! I've suddenly got really busy...

Are you able to follow the tables in the previous attachment I sent you, use an Ohmmeter, and substitute your Red wire for Brown Yellow int the table and do the test?

If in any doubt or you are not able to get results... I would just change it.

Customer reply replied 7 months ago

Customer reply replied 7 months ago
I’m just going to take it a local mechanic. Thanks for the help
Marine Mechanic: Matthew John, Marine Mechanic replied 7 months ago

Ok! Best of luck with it and hope you can find the problem soon!

All the best!
