d into it a little more. I am not getting any spark at all if I plug both coils in. if I unplug the wire on one plug I will get spark on the opposite cylinder. if I reverse the process I get the same result on the other cylinder. so im getting spark from both coils but I can get spark from both when I have them both plugged. whats the problem. why will the same wire fire one cylinder and not both

Experienced gardeners share their insights in answering this question :
You have the wiring hooked up wrong. The way you have it is grounding out the coil that isn’t working. I have ran into this problem at our shop only once. Only after contacting tech support was I able to get it right. Unfortunately I cant for the sake of me remember how I did it. I do remember that when I got it right, it didn’t look like it would work. I am frustrated at my self for not being able to remember.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

Broken, damaged or corroded wire. Timing. Improper spark plug gap. Faulty ignition coil.
Because the ignition module is electronic and does not utilize moving components, it is normally one of the most reliable part of the engine. When it does fail, it is usually due to heat caused from improper wiring of the ground wire to battery voltage.
One of the first symptoms of a problem with the ignition module are engine performance issues. If the ignition module fails or has any problems it can lead to performance issues with the vehicle, such as misfires, hesitation, loss of power, and even reduced fuel economy.
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
If you suspect the coil is dead, you can also remove the coil, plug it back in, and use an ignition spark tester like OEM 25069 to determine if the coil is firing. You can also use a multimeter to test resistance.
You can replace one coil at a time or all at the same time. I would however recommend having all spark plugs replaced with the coils so you do not have to remove coils twice.
To test a coil with a multimeter, you will need to connect the leads of the multimeter to the coil terminals. Once the connection is made, you can set the multimeter to the resistance mode and measure the resistance of the coil.
When you hear a click as you turn the key, a weak battery, bad starter solenoid, faulty wiring, failed starter motor or a seized engine could be the cause.
Because the ignition module is electronic and does not utilize moving components, it is normally one of the most reliable part of the engine. When it does fail, it is usually due to heat caused from improper wiring of the ground wire to battery voltage.

I have John Deere GX345. It does not start consistently. When it doesn’t start the plugs have no spark. The problem is intermittent.All electrical connections look clean and no corrosion. Re- seated all connections. Fuel flow is good because I can smell raw fuel while cranking the motor. I replaced the fuel lines last year. Thank you for your help. Daryl Witowski
ANSWER : Look for a small silver box with 1 wire on it mounted to the motor. It is a temp sensor and will keep it from firing…Just had to replace mine…

I have a john deere 737 mower and it started running on one cylinder. I bought a coil for it and put it on and had the same problem. so I looked into it a little more. I am not getting any spark at all if I plug both coils in. if I unplug the wire on one plug I will get spark on the opposite cylinder. if I reverse the process I get the same result on the other cylinder. so im getting spark from both coils but I can get spark from both when I have them both plugged. whats the problem. why will the same wire fire one cylinder and not both

Spake plug is not spakeing – John Deere Original 130 160 165 175 180 185 Operators
ANSWER : Hi Lloyd
Make sure you are getting spark at the spark plug, to do this:Remove your spark plug and check to be sure you are getting a bright blue spark at the spark plug.You do this by grounding the plug on the head of the engine and cranking the engine or by pulling the crank rope…watching the plug for spark.If you are getting a nice blue spark then skip A below and go to B.
A…If you do not get a nice blue spark then you may need to replace the electronic module.Note: If you have to replace the module be sure to measure the position it is in, it is critical to starting.The clearance can be measured with a “business card”…use the card for the right clearance between the coil and the flywheel.Take a picture for later reassembly.
B…Also take some fine grit sandpaper (not emery) and lightly sand the flywheel where the magnet is located to clean any rust or corrosion from the magnet area.Please rate meBud

Its black and about 2 inches by 1 inch with yellow,red,orange and black wires going to it. Replacement is round shaped with same amount of wires.If no fuel to carb check for flow at filter, if theres flow but no pressure look for a split fuel line in tank between pump and sender.
