Another starting problem on a older tractor

[andrec999]

Hi , I have a JD 2130
I have read alot of threads in relation to the starting problems on older JD tractors, mine clicks when attempting to start but nothing else, the two batteries are two years old and the guy at the garage I brought my tractor to , suggested to change the two of them ,I told him to wait and I will check with this site first, and I believe I found what is the problem according to alot of threads I read , not enough voltage gets to the starter, but it's how to fix it that my problem is. I have read the solution that KUBMECH posted and I have purchase the JD relay switch AM107421, but the instructions are for smaller lawn tractors equiped with different selonoid/starter systems.
The solenoid on my tractor is part of the starter it is attached to it ,and the wires are all connected to the solenoid , not the starterr anyway as far as I can see, I dont see any wires attached to the starter. (the loader arm is in the way and makes it hard to see and work on, new loader attached last week)
That being said, there is two connections on the solenoid, and there is four wires on the relay switch, a red one, a black one, and two purple wich have connectors at the end of each one , a female connector and a male.
I am puzzle to where I attach each wire.
Any suggestions.
Thank you

Sorry I can not help about the relay. Have you cleaned all the battery connections? Ground cable to tractor frame, cables between batteries, cable from battery to solenoid. You may also want to take the two batteries to a local auto supply and have them load tested.

I would agree with Transit's post and ask if you have charged up the batteries yourself?

Yes I recharged the batteries myself and they are ok. Today I started the tractor by connecting a wire directly on the two connecters on the solenoid and it stated right away wich make me believe that the batteries are ok.
I still think that the relay hookup will work. Thanks for replying.

Well... if you started the tractor by "shorting" the solenoid - you've got everything hooked up correctly!

That said, it sounds like your solenoid needs replacing. The coil - magnet is likely weak and doesn't complete the circuit (engage) when you turn the key (clicking noise) and the starter doesn't subsequently crank the engine over.

Weak batteries will result in solenoid "clicking" but if the batteries are weak - when you short the solenoid - the starter is correspondingly weak and does not adequately crank the engine over enough to get it to fire.

The whole purpose of a solenoid is to act as a relay and on some to pull in the starter bendix for engagement. the wiring between the starter and key switch is short enough that no other relays should be required.

As AKfish suggested try a new solenoid switch first. I assume you have checked all the wiring to make sure the connections are tight.

On my 2030 I was able to take the solinoid apart. If I remember correctly the battery terminal in mine was mostly burnt away, but I was able to turn it 180 degrees and get some more life out of it.

This morning I was reading more on the same subject and came across this :
This is from another post:

I had to add the extra relay to one of the 750's that I used to have. It would crank just fine sometimes[/COLOR][/COLOR], other times it would just click the solenoid. After adding the extra relay, it never gave me another problem cranking it! If I still had it, I would take a picture to show it but I sold that one when I bought the 790 I have now. I will try and describe best as I can how mine was hooked into the circui[/B][/B]
1) Get a standard 12VDC relay with one set of NO (normally open) contacts rated for at least 10amps (the more the better). I can 't give you a part number, but a guy at my local starter/alt shop sold me mine. He's the one that told me what my problem was and how to fix it. Your local starter shop may be able to hook you up with one?[/COLOR]

2) On your tractor, find the heavy gauge red wire leading from the battery and going to the starter. One side of the contacts on the new 12VDC starter relay will attach to that wire.

3) The other side of the contact on the new 12VDC relay will attach to the wire on the solenoid that energizes the solenoid on the starter. This is one of the smaller gauge wires attached to the starter assy and it should come from the ignition keyswitch.

4) The negative side of the coil on the new relay will attach to battery ground (or frame).

5) Last connection, the positive side of the coil of the new relay will attach to the key switch so that it gets 12VDC ONLY when you turn the keyswitch to the crank position. Technically, this will be the same wire that you just hooked up in step 3.

Basically, what happens is when you turn the keyswitch to the crank position, the new extra relay is energized, which closes its set of NO contacts. This jumpers over the 12.8VDC coming straight from the battery (through the heavy gauge wire) over to the coil for the solenoid (plunger) in the starter. It will now draw most of its current through the larger gauge red wire, without the voltage drop that you can have through the smaller gauge wire that originally goes to the solenoid.

Good luck, and hope this fixes your problem!

I am sorry but I do not know how to attach another post yet.
I will try to kook up the relay this morning and see what i get.

Sorry for being so unmechanicly incline , but I am trying to do some repairs myself if possible and save some hard earn money!!

Thanks aagain for your help.

Hi again,

(Relay :JD AM107421 Wires: one black, one red and two purple.)

I connected the relay by attaching the black wire to the solenoid where the wire from the switch comes in ,and the red to the other little post on the solenoid were the wire goes from the solenoid to the starter , and I just connected the two purple ones together and the tracor started right away when i turned the key.

I tried it many times and not onces did it just click like it did before, it started evey times, hopely this is the fix it needed.

I will see in the next couple of days by starting it more times.

Today was a mild day, here, near Montreal, about 33F, so it was the perfect day to work on it , as I don't have a garage and have to do the work outside.

I will be posting again in a couple of days with the follow up.
Thank you all.

Have a Happy New Year.

Hi,

Just to bring an update on the issue , my tractor started every time on the first attempt since I installed the JD relay, I am very happy with the fix and hope somebody else profit from the experience.

Thanks to all that posted on the starting problem before ,so I could refere to it , and solve my problem.
