7W-2743 Electronic Speed Switch (ESS) (1) Push button for Overspeed Verification (2) Reset button (3) Overspeed indicator lamp (4) Seal screw plug for adjusting the engine overspeed (5) Seal screw plug for adjusting the crank terminate speed (6) Seal screw plug for adjusting the oil step pressure speed settingThe procedure for the magnetic pickup test will determine if the operation of the magnetic pickup is correct.
Connect a 6V-7070 Digital Multimeter to the "COM" terminal and the "SIG" terminal. The terminals are (ESS-3)and (ESS-4) of the ESS. Set the meter voltage scale to a scale that is greater than 1.5 VAC. Start the engine. Run the engine at low idle or 600 rpm. Choose the one that is larger.If the voltage that is measured is 1.5 VAC or more, the operation of the magnetic pickup is correct. If the voltage is less than 1.5 VAC, go to Step 2.
Stop the engine. Disconnect the wiring for the magnetic pickup at the plug-in connector. Connect the voltmeter to the connector terminals of the magnetic pickup. Start the engine. Run the engine at low idle or 600 rpm. Choose the one that is larger.If the voltage that is measured is 1.5 VAC or more, repair the wiring that is between the magnetic pickup and the ESS. If the voltage is less than 1.5 VAC, go to Step 3.

Loosen locknut (4) and turn magnetic pickup (2) in the counterclockwise direction in order to remove magnetic pickup (2) from flywheel housing (5). Turn the flywheel until a gear tooth of ring gear (6) is directly in the center of the threaded hole for magnetic pickup (2). Install magnetic pickup (2) in flywheel housing (5) .
Turn magnetic pickup (2) in the clockwise direction until the end of magnetic pickup (2) slightly touches the gear tooth. Turn the magnetic pickup for one-half turn in the counterclockwise direction in order to set correct clearance (1). Tighten locknut (4) to a torque of 45 7 N m (33 5 lb ft).Note: Do not allow the magnetic pickup to turn while the locknut is tightened.
Repeat Step 2. If the voltage is still less than 1.5 VAC, replace the magnetic pickup.
