Just as a test touch a pair of pliers handles across the two big lugs on the solenoid to see if by passing it fixes the problem .The solenoid is bolted to the steel of the tractor for a ground, if not and bolted to plastic there will be a second little wire on the solenoid that grounds it, if it is not grounded or has become a bad connection it will not pass battery to the starter.Inside of that solenoid there is two brass buttons and when you turn the key to start position it send currant through the little wire to make a magnetic field inside of it and pushes away a striker bar that lands across the two brass buttons, with time the arcing make the surface on the two buttons bad.
For the starter to work it needs to be grounded or attached to the negative of the battery in some way. Most mowers this is done by bolting it to a steel frame and also bolting the negative of the battery to the steel frame with a cable. Clip your test light to a cleaned area of the frame,now with the pointed end of the test light touch the positive of the battery to see if your light is grounded at the cleaned frame area, if it lights that tells us the ground cable to frame is good,if not go unbolt the end attached to the frame and sand all surfaces clean and reattach and retest.
Now one more quick test with a test light, clip to the ground lead of the test light to the cleaned frame area again, touch the point end to the engine block, turn key into start/crank position, does it light? If it does it indicates the bottom of the aluminum engine has become oxidized like a dirty battery cable does. As a quick fix you can loosen all the engine bolts and twist the engine left and right in hopes of breaking up the crud then tighten them back.
Another quick test is with a set of jumper cables off you car, neg to the engine block on mower and touch the bolt on the side of the starter on the mower with the positive jumper cable, If that starts it you know your starter is good. Inside of the starter is two magnets glued to the sides of the outside steel case, you hit it with a hammer it can and will break them lose and they slide around till they touch the other magnet. I have JB Welded them back if they are not destroyed.

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 :
Should A Solenoid Have Continuity? A solenoid is expected to have continuity between the two large terminals when current is supplied to it. This means that the circuit is complete and the solenoid coils are working how they should.
Blown fuse – Sometimes the simplest explanation is the best one. A blown fuse in the starter circuit could be the cause of a no-start problem. Broken or corroded wiring – Damaged or dirty wires to the battery or to the starter solenoid (or wires that are loose) can prevent sufficient power from reaching the starter.
If you get continuity, then your starter motor is functioning correctly. However, be sure to disconnect all leads when testing the starter because leaving them connected can damage it.
A starter malfunction can have different causes: Electrical connections faulty. Solenoid switch (engaging relay) stiff or faulty. Electric motor damaged electrically.
Continuous duty solenoids relay uninterrupted power for an indefinite length of time, whereas intermittent duty types alternate short bursts of high current, followed by a periods of rest.
Let someone turn on the starter switch while you stand near the engine. When the starter motor solenoid engages, you should hear a clicking sound. If you hear a clicking sound but the starter motor isn`t moving, the solenoid could be engaging but not receiving enough battery power.

Need to replace 9n tractor starter when you turn ignition key the starter just keeps going around.
ANSWER : I suggest that you pull the starter and make sure the bendix unit isn’t stuck on the shaft which may be rusted or dirty and corroded first. If the starter spins then the starter itself is probably okay. Hope this helps you

I have had an electrical problem with this mower since ive had it. I have just changed the solenoid and switch and have looked at the wiring and switches all day and still nothing im getting power to the switch and to the solenoid but nothing happens when you turn the key no clicking or nothing power is not transferring to starter side of solenoid I can jump it off with a wire from the ignition to starter or from crossing poles of solenoid I went and bought another solenoid and that is not it, model is a1991 18.5hp briggs with 42 inch deck do ineed to replace wiring harness or how can i check that
ANSWER : Soliniod should have two small terminals one should get power when turn key to start position the other runs through ground curcuit which runs through break and pto switch most tractors wont start with out break switch working properly i would start with that first the i would go to pto switch. hope this helps

I have a white lawn tractor and i just change the battery and the spark plug and it wont start . I also have current to my switch to start but no current to the starter . Could you solve this.
ANSWER : Do you have power from the switch to the starter solenoid ? What you should have is a battery lead going to the starter relay / solenoid. a battery lead coming from the relay / solenoid to the starter and a 12 or 14 gauge wire coming from the switch to the relay solenoid. Depending on the age of the machine this wire may actually go direct to the solenoid or it may have to go through a couple of safety switches. the first thing I would check is make sure you have power coming out of the starter switch to the start circuit. The terminal on the switch is usually marked with an s for starter / solenoid. If you have power coming out from here then trace this wire to either a safety switch or relay solenoid, keep checking for 12 vdc until you dont have power and you will either find the problem or the bad part… hope this helps you

I have a new battery and when I turn the ignition nothing no sound no power as if the starter is dead or no power to it I checked the power leads and they are all good
ANSWER : If you are comfortable doing it, try using a pair of jumper cables to jump straight to the starter… just to check and see if the starter is working…. does it have headlights? do they come on…?
