Lawn Tractor won't turn over
Comments (8)Saftey switches are just like light switch? either on or off. so if your off the seat the switch would be in the off position. Utilizing your wiring diagram it should show the switch in the correct position in relation with the key position on the diagram. So if you want to check switch say the seat switch with your butt not on the seat the switch should show no continuity meaning the switch is in the open position or OFF position. Now set on the seat and check the switch, it should be in the closed position meaning showing continuity a lowing the circuit to be completed. Or some could be wired opposite Closing making ground to kill the engine again your wiring diagram will show which way it wired? Depending on the model of your tractor you should have at least two other safety switches in the system Blade switch so the tractor won't start unless the blade switch in in the OFF position. Brake pedal switch so it won't start unless the brake is applied. Again these are basic on and off switches and can easily be tested with multi-meter if you know how to test circuits for continuity, know where the switches are located, and can read wiring diagram. But IMO you need to MAKE sure the battery cables (ALL OF them) are tight, free from corrosion (as mentioned ESPECIALLY the Neg. side all the way to the frame. Another thing just cause the battery has 12 volts don't mean it has the ampere required, Dead battery will most likely read 12V (cause there is NO load being applied to the plates) this is why Load test (applying Load across plates in battery) required to determine if battery has enough Ampree (the power to crank any giving engine) to say it good or passed the load test.

Comments (11)OK, lets do the basic's, Check the oil? does it have oil in it? Y or N. battery is is connected and are the terminals clean and tight at both end? Y or N? Are we sticking the key all the WAY in before we turn it to the start position? Y or N. Is the Fuse Blown? Yes or No? Remove the spark plugs and see if you can turn the engine over either by hand or using the starter? Turn or don't turn? Just putting dirty gas into the tank is not going to prevent the engine from turning over, it will just plug up the filter between the gas tank and the engine. "O" does it have a fuel filter installed? yes or no? is it has a fuel filter most likely it stopped any big chunks that would plug the carb. up. But even it the carb. was plugged up the engine would turn over? SO the big question is if the engine don't turn over it was not caused by the dirty gas. But likely the battery went dead? (have it load tested for free at autozone). The connections are dirty or loose or fell off not making a connection from the battery through the ign switch through the solonid through the starter to crank the engine. Or the bigger question you ran it really low on oil and it locked up which had nothing to do the with dirty gas you installed in the engine. there is probably about 20 more questions I frogot or other possibliities causing it not to turn over meaning the engine don't turn and you get NO CLICK? right?...See MoreLawn mower engine won't turn over completely
Comments (1)I think you have scored the cylinder and the engine will eventually fail. By removing the spark plug and trying to turn it you ruled out possible hydraulic lock from excess fluid in the cylinder (oil, gas, mix). The only thing I can advise you to try is change the oil to Opti-4 10W-30 and keep running it. I can't reveal why I think that might work but its not a big risk on your part if it doesn't. You can find it on Amazon....See MoreCraftsman lt1500 lawn tractor engine turns over but won’t start.
Comments (3)Last time I messed with a Craftsman tractor was over 30 years ago...and as far as I remember there a few things you can try is to spray starter fluid into engine cylinder. Take the air filter off and spray some starter fluid into the cylinder (not to much) through the carburetor air intake. If the engine starts and dies it would mean you have spark and compression. Next check the wire to the fuel solenoid, if the wire is lose or disconnected the solenoid wont open and you not getting gas to your carburetor. If that checks out, next check the fuel supply lines and filter and make sure there is no blockage and filter is clean because if not enough air going in, it will not start. Make sure you have fresh fuel (if it was sitting for a while). If everything checks out it could be the carburetor fuel mixing screw (if your model has it on carburetor) that needs adjustment (heck the manual they should have it in there how to adjust). If everything checks out could be that you need to repair the carburetor or get a rebuilt one, next it could be the timing for the spark is off or could be ignition coil, etc items that you need testing equipment and should take to a lawnmower shop unless you know what you doing....See Morebigyellow
