John Deere 345 Time Delay module

John Deere 345 Time Delay module, Can it be bypassed (jumped)?

I got a JD 345 with the symptoms, crank but no spark. From what I been reading on other post this is a very common problem that is caused by the Time Delay Module. I will pick up the part #AM128906 module first thing Monday. While I'm waiting is there a way to bypass or jump out the module to see if it's the problem and if so what wires do I jump? Would like to be able to try this before spending the $20 for the module.

Are you sure that you have this module on your particular 345? They don't all have them ----

The FD590V engines don't have this module --- the FD611V engines do. So, from memory here, I think your serial number needs to be above 070000 for you to have this module on your engine.

Yes I have it, on the left side of the engine, below the fuel filter. I would like to test it before I spend the money on a new one.

Sorry, can't help with a test for that module. The tech manual for that model should describe how to test it. I don't have that manual -- guessing you don't have it either. At $20 or so, most just replace it.

Update: I bought a new Time Delay Module, installed it and hit the key. The tractor started up! A quick and easy fix. The parts guy at the dealer said 95% of the time that when there is no spark at both plugs this is the problem. Thanks for the help.

Thanks for the update --- a lot of the time, we never do get the final resolution. Nice to get it and Congrats.

I have an early 345 with out it. Sometimes when I start it it only runs on one cylinder. Since I do not have the module, Any idea what the problem could be? I have heard or read that it may the plastic cam gear. What about the ignition module? Thank you.

OK this is a little confusing. Does it always run on just one cylinder? Or do both of them work after the engine is started?

Have you checked compression?

No, I have not checked compression. I go out and sometimes I start it and it starts right no problems at all and runs great all day. Start and stop no worries. Other times I go out and it does start up on BUT it is only running on the right #2 cylinder. Now, I did have an issue this spring in which my battery light was flickering on and off. I checked everything I could and found the starter was shorting out internally. I took the starter out and tore it down completely. It was packed with dust and crap. I put it all back together and it worked great. When I was putting it back, I did somehow, put pressure on the igintor box and it broke off one of the corners. I sealed it back up with silicone and it has been fine. In the past 6 weeks, it has started doing what I explained. Starting but only running on one cylinder. Having not worked on it for a while, I did forget about the crack or broken corner on the ignitor. It only broke the plastic housing and not the internals.
I am guessing at this point the ignitor has crapped out. What do you think.

Do your have the service manual for this engine? If not, you can down-load it for free here:

One thing you could try, if the engine starts and runs on one cylinder, can you take the spark plug wire off and hold it near the engine to see if there is spark.

Is it always the same cylinder that sometimes dose not fire?

Look at the service manual. There are some trouble shooting help in there plus the specs for the pulser coils and the igniter that your can check with a ohm meter.

My guess would be some sort of intermittent electrical connection. Check all the connectors. Separate the connectors and check for pins/terminals that have pushed back. Also look for corrosion on the terminals and wires, especially the ground points.

I do have it. I did find the section for the Ignitor module and it does give the Ohm readings but not sure where to ground it. On the machine or can I remove it and use any ground? I am not overly knowledgeable on electric.

Thank you

Do you have a good volt/ohm meter?

Seeing as these measurements are relatively low resistance, you need to set your meter to the lowest ohm setting. Some meters have an auto-scaling. Connect your meter leads together and note the reading. If it is not zero, you will have to subtract the number from the reading you get when connected to the connector terminals.

Go to page 116 of the manual and test the pulser for resistance as noted. You will have to unplug the pulser connector to make these measurements.

Next go to page 117 and make measurements of the igniter. In the chart, the laying down 8 represent infinity, i.e. no connection or open.

If you are still having trouble understanding what to do, do you have a friend at work or neighbor who can help you?

I will try all you mentioned and go from there. I'll keep you posted. Thank you!

Thank you all for the suggestions. Even though it was the expensive part, I really didn't want to get into tearing the engine apart before I tried everything else. It ended up being the Ignitor box. I have an early model and it did not have the $20 ignition module. Found a great deal in this on EBAY and it is an OEM part. $197.00 with including shipping.
Thank again for all the help,

Hum, $197 for a electronic module is a good deal? Must have a lot of gold plating.

I'm glad you got it going.

I understand what you are talking about BUT if you get on line and look up the "Ignitor Module" for a John Deere 345, you will find they range from $225 to $268. The higher is from the Deere dealer. On thing I ahve learned is that when it comes to certain things, buy ONLY OEM Deere parts. Like this and especially O ring seals for hydraulic pistons. You can find them from different places cheaper BUT get DEERE seals.

Take care and thanks again!
