If you checked for spark with a spk plg, did you ground the body of the spark plug while testing?


#3

tonerat

no i did not will try that

Try a new spark plug....

has a new one. can the ignition switch be bad and still turn the motor over

What is the engine fitted to..? and also need the engine number & type off the Briggs to be of any help to you.
Turn the engine over by key and look at the spark plug to see if you have spark (with the spark plug out of engine) making sure it has a good ground.

its a simplicity express briggs 14.5 type 1149-ej model 285707 it was running fine next time i went to use it it would turn over but would not crank getting fuel but no spark pulled ground off coil no spark, i did get meter put black on ground and red on outside of ignition switch next to key and getting 12 volt reading thats why i thought it might have a dead short? thanks tonerat...

If a specific wiring diagram for your tractor could be viewed, a more exact answer might be available but I can't find one online.
In the meantime give all safety switches a good clean and a going over with WD40 and the reverse safety switch if it has one.
You could also post up the markings that are on the back of the ignition switch (photo), how many wire's are there on the one that is marked (M)

Your spark plg will not spark if the body of it is not grounded.

Can you post up the model number for the simplicity express.

grounded even checked with meter to make sure i had a good ground. thanks for all the feed back think ill put it to rest lol...:confused2:

Have you given up on it..?

I had a problem simalair to this with my B+S 18(2 cylinder). it may be that the coil is weak or the gap between the coil and flywheel may be off, it should be approx .014 if i remember correctly. also remove any film built up on the flywheel magnet, with a fine grit paper.

You're going to take your ball and go home? We just started!

going to try the ignition switch:eek:

Also when the coil is off take a file or sandpaper and shine up the two coil mounts,sometime corrosion can set up between the coil and the mounts not making good ground

no luck with ignition or coil all grounds check out safety switches are working right just dont know:confused2:

oyeh model number is wore off

Can you put a meter lead on the (M) ignition switch and the other to earth with ignition switch on run and see if you get continuity, the wire should be PURPLE in colour, come back and let me know please.
Do the test has if you are going to start it,( i.e sit on it etc ) but do not turn key to start.

OK we are not looking for volts here, just continuity at (M) on switch & earth (please read the above again)

If you have continuity between them a switch is earthing the magneto and the engine will not fire (run)


#22

tonerat

not sure for that do have that test on meter comes on and drops straight to zero. if thats helps


#23

being we don't have the right model number I am working off four wiring diagrams here, they are..
Tuff Torq K-56 Models
Peerless Models (1998 and Later)
Hydro-Gear 0500 / 0650 Models
Peerless Models (1997 and Earlier)

The wiring for the magneto are the same (PURPLE) coming from magneto to ignition switch and then onto safety switchers so should be able to work from them, stay with it, I'll not give in just yet..!

Have you set the meter to continuity..?

that purple wire goes to the ground on the coil, the one going to magneto is red with white stripe and the other hooked with it goes to the lights, and the other with the ground goes to the fuel shut off on carb.


#26

T

tonerat

i am getting 12 volts from the switch on the magneto wire but the one comeing from the magneto to the light i have zero


#27

T

tonerat

dont have book on meter theres one spot on meter i think thats for testing that, only thing i use them for is to check for voltage, sorry if i sound dumb.

Wait...! when you say COIL do you mean MAGNETO because COIL/MAGNETO are the same thing..!

The red/white wire (A) ignition switch comes from the alternator (spliced) to go to lights on blue/red wire.
I will post up wiring diagrams for you to look at, take your time.

You should not be getting 12volts on the magneto wire, that wire is there to make earth to kill the coil (magneto)

Post up the make and model of you meter....

so the wire going under flywheel is the charging system now i got ya, so the purple is going to magneto.


#31

T

tonerat

the red is going to charge thats why im geting 12 from there

you will be better to take a lead off the battery, and set your meter to continuity, you don't need battery volts to read continuity because its very confusing, not only that, if you set your meter to continuity and you put it on a wires that has volts in it, it will blow your meter, always play safe.

Can you see the sign for the DIODE below 2000 in green set your meter there with the red lead in red right hand side, and the black in the COM, and make sure you have a lead off the battery.

THAT ONE IS NOT THE SAME AS MINE BUT DOES HAVE THAT ONE ON IT,HOOKED IT UP IT DOES NOTHING


#36

EngineMan

EngineMan

put the two leads together meter should read (0) all DMM are the same


#37

T

tonerat

I WAS ABLE TO HOOK IT FROM ONE END TO THE OTHER IT CAME ON AND WENT DOWN TO ZERO


#38

T

tonerat

I DID TOUCH THEM TOGETHER AND IT DID GO TO ZERO


#39

EngineMan

Thats right, now take off the battery+ lead off the battery go back to post19 and do the test.


#40

T

tonerat

I DID TEST DID NOTHING STARTED AT ZERO AND DID NOT MOVE


#41

EngineMan

EngineMan

meter should read (0) not move, if it does you have continuity, remove purple lead from key switch and try again, if you still get continuity one or more of the safety switchers are closed making the path to earth, so check them, or the coil is bad and needs replacing.

I need to go out and do some shopping so will be away from PC for about an hour, but will be back later.

none at switch. tried changing coil still no spark, set at 10

If you pull the small wire off the coil (kill/grounding wire), it should spark and will eliminate any thoughts of problems with the engine. You must first start at the source of your spark. (flywheel/coil) Then with the small kill wire removed (and you get spark), you will know for certain that the integrity of the ignition system on the engine is indeed functioning and you can go to the next step in the process of elimination.

Yes you are right, sometimes its very hard to get that across...!

Now we are at the meat & potatoes of a problem. This ignition system is so simple and if you have installed the correct (Magnatron solid state) coil and the flywheel magnets to the coil are gapped to a business card, and you have the spark plug body grounded as you test, there "will" be spark. Make sure it is dark so you can see the spark. The spark is not always a bright flash. If still no spark, I am certain the coil is NG

done for today restart in the morning thanks for all the help:thumbsup:

Set your DMM to 20voltsdc, put the battery lead back on, set up the mower ready to start, set key ignition to (run), now with DMM working on the back of the ignition switch put one lead on the (B) the other on (M) you should have no volts (0) if you do there is a path to earth.

getting spark on coil but not when you hook it on the spark plug in the engine cleaned all ingine bolts still no go going to put seperate ground wire from bolt to frame let me know if it will work if it will ill go buy a ground wire from auto parts


#50

T

tonerat

you can ground to the frame and ger spark


#51

T

tonerat

yes ground plug to frame and get spark
