Lawn tractor shuts off after 10 to 15 minutes.
Comments (1)Yes, it could be the ignition module! When it shuts off, immediately pull off the spark plug wire and check for spark. If none, then it is probably the ignition module (coil) When the coil heats up with some running, the coil is probably breaking down inside. After it cools down for an hour, then check again for spark. If there is spark, then replace the coil/ ignition module. Another thing to check is to see if maybe a wire is shorting out somewhere....See MoreHuskee electrical issue in ignition circuit
Comments (13)Though I believe kanmkk is a transient, "one hit wonder", I will address the issue in hopes somebody will benefit from it. While the wiring diagram provided by corvetteguy might not be the "same" as for the Huskee in the OP, it is nonetheless "generic enough" to serve as a guide for hunting down a short circuit. If I were doing the search, I would have my camera with me to shoot photos of the configuration of the wiring at each component and/or draw a sketch of the same so I would know exactly how the wires were routed, and how they connected to the component. When checking for a short, it is sometimes neccesary to disconnect a wiring harness section from one or more components so the harness can be brought out into the "open" for a close inspection. So you'll be able to return the harness to its previous location and with the proper routing, photos are great, and a sketch with notes is a good addition or substitute. I do both. In looking for a short, you need to use all due safety precautions, you already know there is some kind of fault in the system, or you wouldn't be doing this. In regard to safety around the battery, you should disconnect the BATTERY NEGATIVE CABLE from the battery BEFORE you begin your search. This way, you will be working with an "inert" electrical system during the process of disconnecting/reconnecting wiring and/or electrical components. The BATTERY NEGATIVE CABLE can be reconnected at any time in the search if you want to check whether the fuse still "blows". On a typical small tractor battery, I use either a small vise grips plier, or an alligator type spring clamp to hold the BATTERY NEGATIVE CABLE in place on the battery post during the search instead of using the normal bolt and nut. The vise grips or alligator clamp allow you to "snatch" the cable away quickly if you need to. To perform the checks by the following method, you will need an ohm meter, or a "continuity" tester. I prefer a continuity tester that has an audible beep or tone indicating continuity because you can use it in confined areas where reading the visual scale may be difficult. Continuity testers that use an LED indicator are good too. Some continuity testers feature both the audible and LED, some have both and an ohm meter as well. All continuity testers and ohm meters have an internal battery for power and should never be used to check continuity with the vehicle battery connected to the electrical system. OK, disconnect the battery negative cable and let's start looking. If the system fues is blown or removed, install a good fuse of the proper Ampacity. Step 1. Beginning at the key switch, disconnect the entire wiring harness from the switch if a single plug connector is used by the OEM. If individual terminals are used, disconnect the terminal that corresponds to the "B" terminal on the key switch in the furnished diagram. Isolating the key switch in this step will test for a short in the wiring between the fuse and the "B" terminal of the key switch. Connect one lead of the continuity tester to the DISCONNECTED battery negative CABLE, or any other good, clean, unpainted metal surface of the frame of tractor. Test the CONTINUITY TESTER by touching a few other surfaces that you know should be "continuous" with the ground system of the tractor. Essentially, if you are connected to a ground surface anywhere on the vehicle, the tester should show continuity whenever you touch any other ground surface of the vehicle. If the tester shows to be working and that the ground system of the vehicle is "sound", we can begin testing some wiring now. Leave one lead of the tester connected to ground and touch the other test lead end to the wire that connects to the "B" terminal of the key switch (touch the wire, not the key switch). If the tester indicates continuity, it means there is a short to ground somewhere in this circuit. To further check for the location of the short, go to the ammeter (if present) and disconnect both wires at the ammeter terminals. Touch the free lead of the continuity tester to either wire terminal on the ammeter, if the tester indicates continuity, the ammeter is shorted internally. If the ammeter shows to be good, touch the tester lead to either of the wires that you disconnected from the ammeter. If one of the wires shows continuity, that wire/circuit is shorted to ground and you will now have to trace that wire physically to locate the short. Logical places to look are where the wire harness bends around a metal surface edge or goes through a hole in a metal surface. If this test does not indicate a short, go to the next step. Step 2. Go to the key switch. Make sure the key switch is in the OFF position. Connect one lead of the continuity tester to the GROUND TERMINAL of the key switch. On the wiring diagram provided, this terminal is "G". This terminal is where the key switch gets furnished with its connection to the vehicle ground, but we don't need for the switch to have an actual connection to ground to do the following tests, the key switch could be tested even if it were removed from the vehicle and placed on a workbench (non metallic bench). First, check the tester by touching the two leads together (you always want to know that the tester works beforehand). With one test lead on "G" terminal, touch the other lead to the "M" terminal on the switch. You SHOULD HAVE continuity between the "G" & "M" terminals at this time because continuity between those two terminals is what "kills" the ignition spark to stop the engine. Leaving one test lead connected to the "G" terminal, touch the other lead to the "B" terminal of the switch. You should NOT HAVE continuity between these two terminals. If you DO HAVE continuity, the key switch is shorted to ground internally. I expect a short to be found in Step 1 or Step 2 if the fuse was blowing with the key switch in the OFF position. If this test does not reveal a short, we will go to Step 3. (to be posted later if the first two tests sessions do not locate a short)....See Morejohn deere stx38 pto switch shuts off engine
Comments (6)The PTO clutch on the tractor is electro-magnetic and takes a lot of current to operate. If you have a low battery condition this will stop the tractor because you don't have enough voltage to run the ignition system with the PTO turned on. First, check the battery voltage with the tractor off. You should have about 12.75 to 13+ volts (depending on the age and condition of the battery). If the battery voltage is low you could have one or more of the following problems: 1. Old battery that will not hold a charge - needs replacement. 2. Bad voltage regulator - battery is not being charged and electrical system is running on low voltage when the engine is on and the PTO draws enough to shutoff the tractor. 3. Bad stator - battery is not being charged. Of the three possibilities - 1 & 2 are the most common. A bad stator is the least likely but, you can easily narrow this down. Start the tractor and check the battery voltage. If the stator and voltage regulator are working correctly, you should have 14+ volts at the battery. If you do not have 14+ volts with the motor running, then the battery is not being charged - and there is probably not electricity being supplied to run the electro-magnetic PTO clutch + ignition. You can sort this out by starting the engine and pulling the connector from the voltage regulator and looking for AC voltage using a multi-meter. I do not know the exact terminals on that engine - but, you should be able to find a service manual on line in electronic format for about $8.00. Otherwise, you can do this by a process of elimination. Put the probe in the top left contact and check the other contacts sequentially. What you're looking for is about 30 Volts AC from the stator. Then go to the second contact, repeat, etc. If you don't find the voltage - bad stator. This really isn't as likely as a bad voltage regulator. Voltage regulators have diodes in them and other semi-conductors and after being continually exposed to heat, vibration, etc. - they go bad. So, check the voltage regulator with a multi-meter on the Ohms setting. Most of the resistances should be in the 4.5 mega-Ohm area. If you find opens or low Ohm readings between contacts on the voltage regulator - it needs to be replaced. My guess - it's the voltage regulator and you will find several "open" conditions. I just replaced the voltage regulator on a John Deere garden tractor because the PTO would not stay engaged and the battery was always low. If you find the voltage regulator is bad, in your case I would replace both the voltage regulator and battery if the battery is over 2-3 years old as constantly running it in a discharged state has probably compromised the battery's ability to hold a charge....See MoreDoors Lock when I Put Key in the Ignition
Comments (13)A number of Dodge cars have had some form of automatic door locking feature since at least 1989. Usually, after a front door has been opened, all four door locks are activated upon passing through 15 mph. This doesn't hamper the front passengers since their doors will unlock upon moving the inside door handle, however, the rear passengers may find themselves locked in depending on the setting of the rear door child locks. Even when the child lock has not been set, the rear passengers may find that they have to manually move the lock button to the unlock position before the door handle will unlatch the door. There are many variations on this theme. For Dodges, there is a routine of on-off-on cycles executed through the ignition switch that can activate or de-activate the auto-locking feature. I suspect you vehicle also has a similar method that won't require a trip to the dealer. However, I have never de-activated this feature in my car since it does not cause an inconvenience and the procedure is not intuitive; 6 mo later, I won't remember the sequence and would have to look it up again. However, in your case, unlocking all doors upon key removal could get to be a nusiance. If you can't find the arm/disarm procedure in your 3rd party repair manual, you may be able to find it on-line at your local library....See Morefredferrell
