Either a bad battery, a bad stator, (it's like an alternator for small engines) or a short in the wiring somewhere.
If the tractor had a battery in it when you were jumping it, there is a chance that the battery is bad. Try unhooking the tractors battery and trying again. Hook your jumper cables to the battery cables themselves without being attached to the battery. If it runs then just replace the battery. A battery with a short in it will keep the mower from charging and could cause it to die. If there was no battery in the tractor when you were jumping it, then the tractor is not charging and will have to be diagnosed as to what the problem is.
Use battery jumper cables
Battery cables are not supposed to be hot. Cables may become hot if there is too large of an amp draw, meaning there is a problem that needs attention. yes yes
Your battery is not charging due to a problem with the battery cables or a bad alternator.
That depends upon what the starter problem is. If the battery is exhausted, you can use another vehicle's battery, with jumper cables.
Most commonly there is a red cable and a black cable that conect to the battery. The red cable is the positive one. If the cables on your lawn tractor are color-coded, then the cable that connects to the battery post marked with a (+) is the positive.
1. Locate the tractor battery cables. 2. Follow each cable to where it connects to the tractor. One cable will be connected/attached to the tractor chassis/frame. The other cable will be connected/attached to the tractor starter motor. If you don't find this to be true, then discontinue this procedure now. 3. Connect the unconnected end of the cable that is connected to the starter motor to the "+" or "pos" battery post. 4. Connect the unconnected end of the other cable that is connected to the tractor chassis/frame to the "-" or "neg" battery post. 5. Snugly tighten the post connector nuts to ensure a firm/stable electrical connection. Done. Your battery is now connected to your tractor properly.
Charge your battery or tighten the battery cables.
Test battery with a load tester. If battery passes you have a problem with connections or cables.
Bad connectins at battery? Clean connections. Possible loose battery cables on starter or engine block? Clean and tighten cables. If no help, possible bad battery cable/cables. Test cables and replace as necessary. Depending on what type of car, also investigate starter cylinoid. Hope that helps.
check your battery cables loose or dirty cables will cause this. if the problem persists check the reg/rectifier
check the battery and connections/cables
