when you turn on ignition key starter engages

Sorry, my ESP is down, due to Thursdays blizzard. Satillite reception has been knocked out. We are going to need a lot more info from you, if you want some help. Here are some questions we need answers for.

Engine model and serial numbers?
Unit model and serial numbers?
Explain what info you want from us?
What have you checked so far?
Remember, you are our eyes, ears and fingers, so be as specific as possible.

When you turn on ignition switch the starter engages. Motor will Crank but starter still runs. Can not find any shorts in wireing . Purchased new switch and board and it still does the same thing. HELP

Sorry, more questions. Did this problem occur before you installed a new switch? What do you mean by board? Does the engine start? Do you turn the key switch to the ON or START position when the engine starts cranking? If it starts cranking in the ON position, it will be one of two things. You either have the wrong switch (this can easily happen) or the wiring on the back of the switch is wrong. If it starts cranking in the start position, that is good, but then I assume that if you let go of the key, the starter continues to crank. If this is the case, you may have a bad solenoid. I have seen solenoids which will not disengage the energizing circuit, even though there is no power going through it, due to internal corrosion. Have you checked that both key switches are the same, both in position of the terminals and labeling of each terminal. Many inexperienced counterman, mechanics, and DIY's don't know that there are many key switches that look the same, but are wired completely different.

OK you must not know much about John Deere. The Switch is soldered to a board that has wires going to the Ignition Interlock Circuit board AS I have already posted . Thanks for trying to help but you are more lostthan I am

Sorry I couldn't help you out. Guess 30+ years of working in the industry hasn't taught me everything. Nor has JD update school. Good Luck with your problem.

I have worked in the industry for 41 years. Some time we are a little cocke. I assumed you look up a lx277 and study a little before you ask questions.ON IS ON start is start. And if solenoid was stuck the starter would run with the switch off. With that said I figured it out on my own Thanks anyway

On this forum you don't know the posters background. I have found that it is easier to ask a dumb question than make a stupid mistake. With electrical problems I never assume anything, as that can get you in trouble quickly. I have also seen the solenoid stick on JD's caused by a shorted relay on the board. Happy Holidays!

Having the same problem what did you find was the problem Thanks

I came here a little too late...! but it would be nice to know the ANSWER, so why not tell us, it would help others on here.:licking:

Yes, there is a circuit board attached to the ignition switch. I really don't understand why, but I haven't bothered to try either. I'm going with the suggestion the solenoid has "stuck" in the closed position, which will continue to send power to the starter even when the key is released or even turned off.

i am working on a JD 262 that has a switch similar to the one described. problem i am having is to get the starter to engage. also not getting any spark to the plug. i can jump the starter and it cranks, but will not start. just curious if this may mean that the switch is bad???. i check the wiring up to the circuit broad and none of them are bad. the previous owner said they had to fiddle around with the wires going to the circuit board, and they were able to get it to start. i tried it, and no such luck. please let me know what you thank:ashamed::mur::smiley_aafz:

Like I state above, I really haven't looked at that circuit board to see exactly what it does. However, sounds to me like you have a short either on the board or at a connector. I'd take it off and go over it with a fine tooth comb, looking for cracks in the solder.

I also have a John Deere LX277. it is 17 years old and ran until today. No previous issues with ignition switch. Okay, with that said, here I go. There are three stages to the ignition switch on the LX277. Off, On, Start..After cranking, release key, and it automatically returns to on position. NOW, when turning the ignition key from OFF to ON, engine starts turning over. Again, engine starts when turning key from OFF to ON position, and not from ON to START. This should not happen. Does anyone have experience with this issue and if so, if you were able to correct it, how did you do it? New Ignition Switch and Board?

Thanks,

JH

Replace the switch.
If that is not the problem buy the JD service manual for your mower they have step by step proceedures for checking the wiring that people who are challenged working out which end of a screwdriver to hold can follow.
