How to Test the Regulator for a John Deere 41 403 09 AM102596

Save

The AM102596 is a voltage regulator found on John Deere lawn tractors that have single-cylinder Kohler engines. The voltage regulator adjusts the electrical current coming from the stator so that the battery is charged with a smooth current that won't damage the battery. Testing the voltage regulator requires knowledge of how to use a voltmeter. This procedure takes 15 minutes to complete.

Park the machine on a hard level surface, set the parking brake and remove the key from the ignition. Raise the hood and locate the voltage regulator on the right side of the engine. Bolted to the side of the engine is a small silver box. This is the regulator.

Disconnect the plug from the bottom of the voltage regulator. Turn on the voltmeter and set it to Ohms scale. Locate the ground wire found under the bolt holding the voltage regulator to the engine block. Place the black lead from the voltmeter to the bolt with the ground wire underneath it. There are three prongs found under the regulator.

Place the red lead from the voltmeter to the furthest prong from the ground. Check the reading. It should be 31.2 M. If this is not the reading, the voltage regulator needs replacing. If it reads 31.2 M, move to the next step.

Keep the black lead on the ground and move the red lead to the middle prong. Check the reading. It should be between 8 and 9 M. If this is not the reading, the voltage regulator needs replacing. If it reads between 8 and 9 M, move to the next step.

Keep the black lead on the ground and move the red lead to the prong closest to the ground. Check the reading. It should be between 8 and 9 M. If this is not the reading, the voltage regulator needs replacing. If all these readings are within the specifications, the voltage regulator is working properly.
