Hi guys, My L35 has always started and ran just fine. However, now I can't get it to start or even turn over. Sometimes I get dash lights and when I try to start it, I hear one click from the motor area. I have replaced the new battery and installed a maintainer on it. I have replaced some of the relays. Its been tough trying to find the actual manual. My L35 manual shows a digital dash. I have researched anything I could find on line. I tried to jump start it per one of the forums. It does nothing. Any guidance would be appreciated.

How about some photos of the top of your battery.

Because you say you cannot jump start the machine, assuming you did the jump correctly, it really narrows down the problems to cables and their connections to the tractor frame, starter and battery.

If you have a multimeter, the attached DENSO starter trouble shooting steps will quickly point you in the right direction.

Honestly ,you NEED a good,accurate wiring diagram to even try to troubleshoot.
How old a machine,
are the battery cables new?
checked ALL the fuses ?
ant damage to safety switches ?

Your symptoms are classic bad connection. Might be something else, too, but cables and connections are the place to start.

Start with the battery cables. Both cables (positive and negative), both ends. And "check" doesn't mean look at them. Disconnect them, clean the terminals. Flex the cable. Sometimes corrosion can wick up into a cable and hide there. If it's there, the cable will be stiff. Flexing it will break up the corrosion. Listen and feel for that. Crunchiness = corrosion. You might break the cable completely. That's good. If it's borderline, you want to break it so you know where the problem is. Get rough with them!

Thanks Dave. I replaced the battery and both cable ends with good connectors. 13.4 volts at the battery. I followed instructions to try and jump past the tractor to the starter from a post in the forum. We will be trying additional trouble shooting tomorrow.

I have downloaded everything I can find. This is a 1994 L35 TLB Ser # 70760. I replaced the alternator, start key switch assembly and we installed a JD starter relay to protect the voltage drop. I worked on sewage lift station control panels and have several Fluke meters. I have been research relay diagnostic information for the various relays. In our field when we get these weird electrical issues in the panels, we call it MES...Mysterious electrical shit. I know it's got to be some simple stupid issue. I just don't understand why I get dash lights sometimes and when I do and try to start, I hear one click and then nothing. I did some feedback about the fuel shut off switch and will try to find a test procedure on it as well.

I don't know if this diagram will be legible. You're making this too complicated. The glow plug timer, key stop timer, none of this prevents it from turning over. You say you replaced the cable ends, not the whole cable, so like others have said, I'd say you have a bad connection.

You could also have a battery that measures 13.4V but totally fails under load. Have had that happen a couple of times and it mimics the symptoms you’re experiencing. If that’s the problem, jumping it with that battery still in it is unlikely to change its behavior. You have to remove the failed battery to get it to change behavior.

Although not the likely solution, since you’ve checked the likely stuff I’d swap out the battery for one you know is working and is of sufficient size (as in the battery out of a car/truck/other piece of equipment you have sitting around that you know is functioning properly.)

No, I’m not an electrical engineer or expert on battery design so if you want an explanation of what failure in a battery would cause that behavior, I don’t know. I do know I’ve seen that exact behavior quite a few times. About 95% of the time it was a bad connection/cable. A few times the issue was internal to the lead acid battery and swapping it out fixed the issue.

Hey donestone
I have an old L35, but I'm guessing the wiring is similar.
On mine, there is a 40 amp slo-blo fuse in the starting circuit.
Double check that as well as the other fuses, ground, and aforementioned items.

Are any wires corroded inside their coverings? I hate that.
I'm in process of restoring my L35 and the electrical on it is a mess.
Also check the fuse box itself for corrosion - I have to replace my original due to corrosion.
You can even swap the battery just to be sure it works in another vehicle.

There are 3 micro switches on the glide shifter, PTO and parking brake. ensure they are working as they are to prevent starting in gear, brakes on and with PTO on. The switch type is included in the attachments. The PTO switch is a pain to get out. You can jump them temporarily as a test.

Do let us know the problem when you find it.

Guys, you have been wonderful. My apologies for the delay in responding. Out of frustration, I replaced every fuse, cleaned the fuse box with compressed air and I also found a little screw with a neg wire just above the corner of the fuse box that was loose. I tightened the screw, replaced the fuses and it started up like it had always did. I'm a total idiot and have demonstrated several "small stupid attacks" during this journey. Once again, thanks to everyone for their wonderful advice. Be well.

Excellent! LOL If you're stupid, I guess we're all stupid - things like this happen all the time. It is indeed part of the journey! Keep Tractoring!
