How to Troubleshoot a John Deere Starter
- 1). Check the battery. You want to check this before you check the starter because the battery supplies power to the starter and, if the battery is dead, the starter won't respond. Check the connections and look for corrosion. If unsure, you can use a battery meter to check the power output.
- 2). Check the wiring connections on the starter and the starter relay. You're looking for loose connections in either spot. Tighten any connections as needed. To find the starter, you need to look on the top back of the engine.
- 3). Check the fuse. If the battery is supplying juice and your connections are solid with the starter and starter relay, you may have a blown fuse. The fuse panel is located right under the hood of the tractor. If the fuse has a break in the internal connection, you'll need to replace it.
