The John Deere 345 is a great lawn tractor, but it can be difficult to start if the ignition module is not working correctly. There are a few things that you can do to troubleshoot the problem and get your tractor running again. First, check the battery to make sure that it is fully charged.
Next, check the connections on the ignition module to see if they are loose or damaged. If everything looks good, then you may need to replace the ignition module.
If you own a John Deere 345 lawn tractor, you may have experienced ignition module problems. This is a common issue with this model of tractor, and can be caused by a variety of factors. If your tractor won’t start, or if it starts but then stalls shortly afterwards, the ignition module may be to blame.
In this blog post, we’ll take a look at the most common causes of ignition module problems on John Deere 345 tractors, and what you can do to fix them.
One of the most common causes of ignition module problems on John Deere 345 tractors is a bad ground connection. The ground wire that connects the engine to the frame can become corroded or damaged over time, causing an electrical problem that can cause the ignition module to fail.
If you suspect that your ground connection is the problem, clean all of the connections and make sure they are tight. You may also need to replace the ground wire if it is badly damaged.
Another common cause of ignition module problems on John Deere 345 tractors is a faulty key switch.
The key switch provides power to the ignition system, and if it fails, the engine will not start. Replacing a faulty key switch is usually a simple fix, and should resolve the problem.
If your John Deere 345 tractor has been having difficulty starting recently, it’s likely that one of these two issues is to blame.
Luckily, both are relatively easy to fix yourself – so there’s no need to call in a professional!

How Do You Test a John Deere Ignition Module?
To test a John Deere ignition module, you will need a few tools. First, you’ll need a multimeter to test for continuity and resistance. Next, you’ll need a 12-volt test light to check for power.
Finally, you’ll need an oscilloscope to check for waveform integrity.
Before testing the ignition module, you should always check the fuses and relays first. If they are all intact and functioning properly, then you can proceed with testing the ignition module itself.
To test for continuity, connect one lead of the multimeter to ground and touch the other lead to each of the terminal points on the ignition module. There should be continuity between all of the points. If there is an open circuit or high resistance reading between any of the points, then the ignition module needs to be replaced.
To check for power, use the 12-volt test light and touch one lead to ground and touch the other lead to each of the terminal points on the ignition module (one at a time). The test light should illuminate when touching any point that has power going to it. If there is no power present at any of the points, then further diagnosis is needed to determine where the problem lies.
Finally, to check for waveform integrity, connect an oscilloscope probe to one of the terminals onthe ignition module while monitoringthe output signal onthe scope itself. The waveform should be clean and consistent with no spikes or dips present.
Why is My John Deere Cranking But Not Starting?
If your John Deere tractor won’t start, there are a few things you can check yourself before calling a technician. First, make sure that the battery is fully charged and that the connections are clean and secure. Next, check the fuel level and ensure that there’s fresh gasoline in the tank.
If those two things check out, then it’s most likely an issue with the spark plugs or ignition system. You can try cleaning the spark plugs and checking the gap to see if that solves the problem. If not, then you’ll need to call a technician to diagnose and repair the issue.
What Engine Does a John Deere 345 Have?

John Deere 345 Time Delay Module Symptoms
If your John Deere 345 lawn tractor is experiencing any of the following symptoms, it may be due to a problem with the time delay module:
-The engine will not start
-The engine starts but then stalls after a few seconds
-The engine runs but is very sluggish and has reduced power
Conclusion
If you own a John Deere 345 lawn tractor, you may have experienced ignition module problems. These problems can be caused by a number of factors, including age and wear and tear. Ignition modules are responsible for providing the spark that ignites the fuel in the engine, so when they fail, the engine will not start.
In some cases, you may be able to replace the ignition module yourself. However, it is important to consult your owner’s manual or a qualified repair person before attempting any repairs.
