Check the coil impedance on the primary and secondary side. You'll have to disconnect the battery negative cable so you don't short something out. Unplug the spark plug wires and the two sets of smaller wires connected to the primary side of the coil. The primary coil reading should be between 3.7 ohms and 4.6 ohms while the secondary (spark plug side) should be between 34.2 k-ohms and 41.6 k-ohms. If the resistance values you measure are outside of these ranges, you need to replace the coil.

SOURCE: john deere lane rider la135 wont start.

You don't mention if they are on and are bright or are week. Do they dim when trying to cranks the motor? I would start with checking the ground wire at the battery and where it connects to the frame. Make sure both are clean. From there, have the battery tested and then the starter.

No spark one plug f725 john deere


Did you replace the IGNITION coil or the "PULSING coil"? There are two different types on that engine. The ignition coil makes the high-voltage spark, the pulsing coil is a sensor that tells the ignition control module when to tell the ignition coil to make that spark. The pulsing coil is pretty inexpensive on eBay.

If you change both the ignition coil and the pulsing coil and the problem still persists, you may need to replace the ignition control module.

Unfortunately, they don't make these things simple any more, or easy to troubleshoot.

John deere 110 engine cranks but no spark


Check that the ignition coil kill wire is not shorted to the frame.
Check coil to flywheel gap. A business card between coil and flywheel will set correct gap.
Coil could be bad or ignition switch is not releasing the kill wire in Run/Start positions.

John deere gx345 has no spark at plug what is the cause?


need new coil pack or have short in harness grounding engine from running. check fuel line to carburator. 1. take float bowel off bottom of carb. do not touch float or pin holding float. crank engine over until fuel comes out of carb. If fuel comes out, you don't have fuel problem. put float bowel back on carb. 2. check for spark. take spark plug out of mower. put wire back on plug and place the threads on head [or metal of engine to ground the plug]. crank engine over for a few seconds to see if plug gets spark . [always double check with another spark plug that is good]. [[ Remember!!! you have to have someone sitting on the lawnmower to start. unless you by-pass safety switch [only do this if you understand how the safety switch works. NOT EXPLAINED HERE!!!]] If spark is present, there is no grounding problem. when engine is cool. 3. CHECK COIL PACK. for continuity. When the coil pack gets hot it will stop any juice to the plug. A>Check temp sensor B> Check Safety switches grounding out. C> Check for cut wiring harnes. [loose wires rubbing against pulleys, wires cut by rodents]. Hope this helps.........................GAS

John deere model240 mower will not start. Have replaced coil and still not getting spark at the plug . Engine turns over strong


Only option left.... 12 volts feeding coil is not there. The ignition key applys the 12 volts to the coil in the "Run" and "Start" positions. Verify 12 volts at input to coil and then (if needed) follow wire back to key and confirm voltage there....and (if needed) follow input wire to key from battery. One of those critters is open - since you have already confirmed the coil/spark plug wire is not at fault.

Jonh deere ryding lawn mower won't start


try making sure your getting gas to the carb,and to the spark plug if you can choke it and try to start it but fails check the spark plug if its wet with gas then the plug is not firing or your ignition coil is dead also check for debri or foreign matter in the gas lines and filters but if it has set for awhile most of the time the jet become clogged in the carb but most importantly make sure the gas is good and free water dead gas can cause a problem of that nature.hope this helps.

My 2002 honda accord check engine light has been on for the past month. i took m y car to get the engine codes read and it said cyl 2 and 4 misfired. the car drives good but starts losing power when i go...


Did anyone check the spark plugs and wires? Make sure the Spark plugs are the correct NGK Spark plugs, nothing else. Fuel pressure is another thing that need to be verified under a load, lke the mountain you are having trouble with.

I have a John Deere 317 tractor that does not start. The engine turns but does not fire. The plugs and points are good. I do not get a spark at the points or plug. What should I check next next.


We will be testing for voltage to the points, coil, engine to tractor wiring harness, ignition switch

Tools needed:
volt meter to read 12 volts, or test light

1) with the points open: is there voltage at the connection wire at the points
If yes; adjust points to .020" and try to crank engine and check for spark
*** you may want to determine if condensor is connected to this wire also
if no
2) check point side (neg or - ) of coil for voltage
if yes, engine should start
if no
3) check for voltage at the + side of coil
If yes, coil is bad
if no
4) check wire connector from engine to frame wiring harness
if yes; engine should start

if no
5) check wiring on the back of ignition switch
if yes; engine should start

if no
6) check that ignition switch RED or BATTERY supply wire has voltage
if yes; switch is bad

if no
7) check supply wire and circuit breaker connected to the battery side of the solenoid
if yes; engine should start

if no; circuit breaker could be at fault or wire connector at battery supply

John deere mod 345 no spark


first find the wire that is grounded to mower to ignition
and check that it is isolated if mounted on some plastic and disconnect it
if it runs to start switch check wire for cuts also
most common problem is the coil located under the top plate held on by 4 /5 screws on sides.
remove top and follow plug wire back to coil

you can clean the curved edges of coil that are against motor {magneto} with sand paper and clean mag
remove plug and lay threads securely agains frame and check for spark {hold by wedging not by hand as you can get a jolt!}
