Electrical Troubleshooting for a John Deere 1070

Electrical problems with a John Deere 1070 tractor often stem from a fixable problem with the tractor's battery. If the battery isn't the cause of the tractor not starting, you need to troubleshoot other possible causes or see a John Deere dealer, if necessary. Other common electrical problems can occur with the front headlights, which also can be fixed without the help of an expert.

    • 1

      Turn off your John Deere 1070 tractor.

    • 2

      Try to start the tractor. If the engine won't turn over, then the electrical problem could be with the battery.

    • 3

      Move the mower engagement lever to the "Park" position if it is in the "Engaged" position, then try starting the tractor again.

    • 4

      Lift up the front hood on the tractor and inspect the battery terminals to see whether they're corroded. Clean the terminals with a dry cloth.

    • 5

      Connect jumper cables or a battery charger to the battery terminals to charge the tractor battery. Turn the key to start the tractor again once the battery is charged.

    • 6

      Replace the battery, if the battery won't charge at all. You might have a dead cell in the battery -- you can buy a battery from a John Deere retailer.

    • 7

      Check the lights, if your engine is turning on, to see whether you have an electrical problem with a front headlight not coming on.

    • 8

      Open the front hood and remove the screws from the side panel that the broken light is on.

    • 9

      Connect the light plug at back of the bulb connector if it is disconnected. If the plug is connected, the unfasten the old bulb and replace it with a new one.

Tips & Warnings

  • If the tractor still won't start after changing the battery, you might have a blown starting circuit and you should contact your John Deere dealer for repair.
