on going starter issue

[plott hound]

ever since i bought my 2012 hdi ive had and issue where 50% of the time when i try to start it i get only a click and no crank.release the key and try again and away it goes as it should.initially i thought the battery may have been weak so i chucked a good agm battery in but the same thing happened.took the starter out and replaced it with my brand new spare but got the same result.changed the spade connector that goes to the starter solenoid but there ws no change.i wired in a separate relay that took power right from the main power from battery then to the the starter solenoid.but it just looked gawdy and seemed like an accident waiting to happen so i removed it.is it possible that i have defective key switch?or maybe the wire going to the starter solenoid is not big enough to carry the voltage?or is there a starter relay in there somewhere that not right? im grasping at straws here,lol and need some direction. thanks

start checking, moving, wiggling grounds. add a ground strap from the engine to the battery. you can even test this with jumper cables. another way to find the issue is to wash the machine and try to start it. look for steam coming off anything while trying to crank and this will point to a bad connection. may also just be a bad solenoid, these tend to use the cheap lawn and garden type. try jumping the 2 large contacts on the solenoid a dozen times. if it cranks over every time the solenoid is probably the issue. i just use a pair of pliers or a screwdriver to jump those

You beat me to the punch Racerone, On my Max is was always a ground strap issue but I did have a solenoid go out on my max, there is also a possibility of a dead cell in your battery.

the starter has the solenoid built into it,not external.i went through it a few years ago and checked the grounds then again in the spring when i had the engine out and sitting on the bench.i will try the extra ground strap from battery to the engine though,thats a great idea. thanks guys.

When you bypassed the original setup did you problem go away?

Question:does this intermittent problem occur on a cold engine.? I have a similar problem but only occurs with a hot engine.

The problem occurs for me hot or cold.

I never really gave it a chance,the gawd awfull mess of wires turned me off so i removed it and went back to factory.

Assuming the new starter and battery are good all is left is ign sw ,wiring and solenoid. If youre getting a click probably switch is fine . I would make sure all wiring and connections are clean. Clean ring terminals battery connections. make sure no white powder on wires. Make sure ground connection on block is clean.your starter grounds thru its body so as long as the block mount is clean. Adding a ground to the starter would help anyways.
Can swap relay as well
Does your machine have a neutral safety switch?
If so bypass it and see if any change.

The ground to a starter bolt may help, I believe Kohler engines may to be cleaned where the starter meets the block now and again.

thanks argo jim,will add that to my list of tests.

here is a how to on adding a solenoid.

and here is a thread i found on the issue https://www.mytractorforum.com/threa...ractor.131077/

tomorrow after work i will start running through all the suggestions and if none work i will throw that relay back on and give it a chance.

As I suggested earlier this problem is so similar to the one had, except mine only occurred with a hot engine during summer temps . And invariably on the second crank it would fire up. Some heavy equipment friends suggested “heat soak”( google).
Installed a heat shield between starter and engine block....so far no dreadful “click” miles (opts kms) back in the bush. BTw I’m driving 04 Argo avenger.

thanks for that murray40.i had a really good look at everything today and of course the starter engaged evertime i tried it,no click.i wired the bosch relay in again and will leave it alone and see if the click is eliminated.if it does maybe i will chase the green wire back from the starter to the key switch and see if i can replace it with a heavier wire?????

Intermittent problems are always the worse to correct. One other change I made was disconnect the cooling fans from the ignition and wired them to a separate toggle switch. Not sure about newer models, but as soon as the ignition was turned, before cranking mode, the fans on mine would be running.
