Question about John Deere Lawn Tractor Seat F710 F725 F735 Slidetrack ()

Open Question

F710, There is no spark, I bought a new spark plug and a new coil, no spark. However, if I stick a screw driver into the cap and check against the motor I get spark but it is weak. Again nothing with the spark plug. Any ideas what to do next? I have checked with an ohm meter all the wires and they are all good. I have taken the white ground wire that grounds the coil to shut the motor off off and it doesn't change anything. The motor died last fall and I took it to my local John Deere dealer, they billed me $540. Brought it home and put in shed. Pulled out two weeks ago, made it about 100 yards and it died again. Any ideas to try on my own before I break down and take it in again.

Do'nt know the JD, but if you have power to coil and distributor is OK, go looking at the condenser and points ( old engines), or the electronic unit if its a modern unit. Something has to make and break the contact to the coil.

SOURCE: I have a John deere 317 tractor that does not start.

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

SOURCE: Lack of Spark

If all of your tests are correct, the thing remaining is the ignition coil. A bit of a pain to get at and expensive too. Parts diagram here. Before you buy a new coil, see if there might be just a broken spark wire or loose connection at the spark plug contact end.

Will not start, no spark

try this test. take off the spark plug cap ( they unscrew ) snip a small piece off the ht lead ( as the metal inside will be chewed from the thread of the cap ) with a new cut hold the lead against any metal near it ( the cylinder head etc ) and pull it over. you should see a spark from the lead ? if you do you can replace the cap ( it will have new wire to screw into now ) and try fro spark at plug ( no spark new plug needed ) ..if you get no spark from the ht lead unscrew it from the coil and try a new lead

First let me say I don't know of an aftermarket coil made for this blower.

Disconnect the kill terminal of coil and see if it is generating a spark. There could be a short the wiring if it is now generating a spark. Also make sure coil has a good electrical ground to the cylinder. If coil is not generating a spark with kill wire off and the coil to cylinder ground is good then coil is most likely bad.

Getting firebtoo cool but not the spark plug on 99 Suzuki GSX F 600 Katana

Assuming the spark plug is okay it could be the coil itself, the ht lead or the cap that is causing the problem. Try detaching the lead from the coil and touch the screw in the coil that the lead was attached to against the top of the spark plug and see if the plug sparks directly connected this way (its a bit awkward to do but perservere). If it sparks the coil is working, if no spark then the coil is suspect. Re-attach the lead without the cap and test again. Spark, then that is okay. No spark, ht lead faulty. If you get a spark at this stage then try again with the cap fitted as breaking all connections then re doing them can sometimes fix it. Caps have a set resistance to them but sometimes they break down and the resistance becomes too high and a spark isn't produced.
I am saying to do it this way in order to save money, but if you buy a new lead and cap and the problem persists then at least you will have a spare set.

Chevy cavalier 1998 2.2l Engines shake and when change to speed, it goes off

Carlos it sounds to me like your running with a dead cylinder. I want you to test for spark on all four of your plugs one at a time. You can buy a spark tester at most auto parts stores or just use a small diameter but long screw driver. With the engine off key off pull a plug wire off and insert the plug end of tester into the wire boot or stick the end of the screw driver in and attach the clip on tester to engine block or hold the shaft of the screw driver an 8th of an inch from the block an have a helper crank the motor ( be sure to keep all lose clothing and items away from moving parts) if you see spark jump the gap it's good. You can also remove the spark plug stick it back in the wire boot and holding the boot hold the threaded end of plug against the block. And watch the electrode for blue spark. I'm thinking you have a bad coil.

96 Z71 new coil,ignition modual,plugs,wires,cap&rotor,spark from coil,no spark at plugs

Hello: Remove the distributor cap. Check the rotor, see if there is a black spot where the metal piece makes contact with the carbon stick out tha makes contact with the coil. Did you replace that piece when you replaced the coil, it should have come with the new coil? Also did you reinstall the ground strap that was under the coil and went to the stick-out that the black connector plugs into the cap?

No start , fuel present , spark present but appears weak

if the spark is orange it is week. It should be whiteish blue. Pull back the rubber boot on the cap at the wire end. unscrew the cap and remove, cut about 1/8 inch of wire off and screw the cap back on.check again for spark.check all 4 plugs seperatly. take a flat head screw driver and tighten clip inside plug cap were plug goes. NOT TO Tight you can crack the cap. If this does not help you might need a new coil.

How do you test a GM Ignition Coil for Spark and if it is strong enough

The way to test this coil is to remove a spark plug wire and put a screw driver into the boot put the screw driver 1/4 inch away from bake metal crank over the engine if it has a blue spark it is ok. The most common problem on these coils is not the coil itself but the rotor button in the distributor cap so repace the distributor cap first if you have a problem with it running. you also need to use dielectric greese on the boots of the plug wires so they will not arc out against each other. yo test the coil you need a ohm meter and need to test the primary ans secondary windings with ohm meter, do you own one if so let me know If you need more help post a reply here.
