Help Introduction and plea for help

Hello all,

I have a JDeere L145 lawn tractor with a little problem. I am no mechanic but do the standard maint, oil change, tires, mower deck belt/blades, lubrication etc.
I have 3 acres on a family farm that has (2) 1938 houses..and yes I do the remodels/maint on those as well.

I want to ask for help with a starting issue I have been cursing for 3 yrs. Yep I put it off that long.. The key clicks just once in start position, If I do that enuff times and use the proper curse words it will finally start. It starts ez when the key "engages" Im thinking solenoid since the starter doesnt seem to have issues. Seems ez enuff to replace all the parts if I just knew which to replace. Appreciate it

Re: Introduction and plea for help

Welcome to the forum!

I've never had to delve into starter/solenoid issues, myself. But in some reading here & there, I've seen mentioned that you can bypass the solenoid by connecting a jumper cable from the battery's + terminal to the solenoid-connected lug on the starter. The solenoid is just a big switch. So by connecting from the battery straight to the same location, you are just going around the switch.

So if it immediately cranks to life, I'd suspect the solenoid. And if the problem persists, it's probably the starter. The solenoid should make a "click" when you turn the key to the Start position. If the solenoid shows no activity, that might also point to it being bad.

Re: Introduction and plea for help

Ty for the speedy reply. There is a click when the key is turned to start position. however nothing happens. I have to turn off and then to start sometimes several times until the starter finally engages. I will try the bypass you mentioned to test that out to see if its the solenoid or starter. Thank god the parts are inexpensive.

Your help is really appreciated.

Good luck! I've also heard people mention rapping on a solenoid, like maybe with a screwdriver handle, to help un-stick them.

Re: Introduction and plea for help

Corrosion can be an issue one of the connectors also.
Yes, jump battery + to starter (bypasses solenoid), it it cranks ok that's it.
Another trick is when in crank mode, as you hear click...whack solenoid with hammer (a rap, not super hard). If it cranks... It's bad.

Re: Introduction and plea for help

You can bypass the solenoid AT the solenoid. This is an electrical/mechanical switch. The smaller gauge wire(s) (there may only be one if it's using the base of the solenoid for ground) activate the electromagnet inside and causes the metal bar (inside the solenoid) to make two contacts allowing a higher amperage flow to the starter. The larger wires on the solenoid is what to use a jumper wire on. Make certain it's a heavy gauge or it'll burn you (it'll act like a fuse with light gauge wire).

Re: Introduction and plea for help

Take a look in the Technical Exchange section and read up on the Starter Assist Relay article. Your symptoms sound classic. No sense in spending big $$'s on a solenoid when a simple relay will fix you up. Let me know if you need any info on this. Also, take a look at the Youtube video in my signature.

Need a relay with wiring harness for your own assist at a fraction of the cost?

You might check your seat, neutral, mower deck, etc safety switches as well. I dont know that model directly, but a faulty safety switch can raise havoc.

Re: Introduction and plea for help

if u have a battery charger that puts out 30-40 amps u can hook it directly to the starter.. (make sure the red wire goes to the starter terminal & the black wire u can hook it to any solid place on the engine).. then it will start the engine as u turn it on.. this will tell u if the starter is good..

I have started engines with no battery this way like on a test stand..


what machine r we workin on..


what is the model or make of the engine..

Re: Introduction and plea for help

If you find the starter doesnt work, it is a somewhat common failure to have a dead spot in the starter. Starters used to be rebuilt, but now its just a replacement.

Re: Introduction and plea for help

By the symptoms, it's the solenoid......I'd put a bit of money on that.

Re: Introduction and plea for help

As someone who has the starter assist relay on his tractor already, to solve what sounds like a very similar problem, please do take a look at Brad's video and see if that's what you're seeing. The root of my issue was that yes, there wasn't enough voltage coming through consistently enough through all the existing wiring to engage the solenoid. Trying and trying, and eventually it would start. Here's a link to Brad's original thread about sourcing and installing a starter assist relay...

the starter assist was put on the STX series.. have yet to see if it was if it was on other machines..

the L series had a lotta B&S engines.. they were common to a valve adjustment.. I have a Scotts version of the L120.. last summer I did the valve adj.. the starter would engage the flywheel & stop there.. it may have moved the flywheel some..

the L120 I got was subjected to a rollover.. that blew the engine.. (had 2 busted rods).. I replaced the engine with a 2 year newer one.. it also had one more HP too..

after rereading this tread the OP has a L145 machine..

Re: Introduction and plea for help

It's super easy. All you need is one heavy duty jumper cable. Good car jumper cables will work fine, just use ONE of them.
1)Tractor in neutral, battery negative to good engine ground. If it starts...you have a bad ground.
2) battery positive + to starter motor...if it cranks, starter is ok.
3) battery + to starter solenoid small terminal...if it cranks, solenoid and starter ok...check ignition switch. If it doesn't crank, step 4.
4) battery + to solenoid large terminal (one that goes to battery). Cranks when key turned...check that battery + to starter wire. Ignition switch is ok.

Another inexpensive test is a 12v test light.
Clip lead battery negative ground. Tip to battery + positive. Should be bright. Crank on it...should stay bright. If not, check battery. Test light bright when cranking, move up to starter solenoid. Should be bright all three terminals in crank mode.

all of that testin requires a good ground.. if the ground is no good how does the electric get back to the battery..
