| The Starter Switch is activated from the right handlebar switch housing. It is fed power when the Run/Stop switch is in the RUN position. When pressed, the Starter Switch (button) supplies power to the Starter Relay, which is located near the fuses. When activated, the Starter Relay will supply, thru it's controlled contacts, power to the Starter Solenoid. Starter Relays are subject to corrosion and oxidation. Since they are relatively inexpensive, the Starter Relay should be replaced every 5-years or sooner if there is any question of its operational functionality. | The Starter Switch is activated from the right handlebar switch housing.

| Technical Note - The pull-in windings are needed to initially move the plunger. Both the pull-in and hold-in windings are activated when the starter relay activates the solenoid. The power to the pull-in windings completes its path to ground thru the motor windings, while the hold-in windings have their own permanent ground path. Once the plunger moves forward into position, and the high-amperage contacts are closed, the pull-in windings are essentially disabled because the power on the output contact **(B)** makes both sides of the pull-in winding equal to 12v. This leaves only the magnetic field of the hold-in windings to keep the plunger in place. | Technical Note - The pull-in windings are needed to initially move the plunger.

| - | The high-amperage internal solenoid contacts are shown in that diagram at the connection labeled '8'. The solenoid activation circuit (which includes the Starter Switch and the Starter Relay) is identified simply with the dotted line from the battery to the windings at '10' & '11'. | + | In the left diagram above, the high-amperage internal solenoid contacts **(B)(D)(B)** are labeled '8'.

| When the solenoid plunger moves the pinion gear ('1') into mesh with the ring gear('13'), the starter motor is already starting to turn and helps the gears to mesh laterally. Once engaged, the starter motor will continue to rotate the ring gear (as long as the starter button is pressed) until the engine fires. At that point, the overrun clutch ('12') in the solenoid gear assembly allows the ring gear to run faster than the pinion gear shaft without harming the starter unit. When you release the starter button, the solenoid will retract the pinion gear from engagement with the ring gear and the starter unit will return to a resting state. | When the solenoid plunger moves the pinion gear ('1') into mesh with the ring gear('13'), the starter motor is already starting to turn and helps the gears to mesh laterally.

| From examining the solenoid rebuild kit (31604-06) for this model, it appears the solenoid plunger rod is longer than that used with the Sportster 1.2KW stock model starter. So this kit may not work with the XL models. | From examining the solenoid rebuild kit (31604-06) for this model, it appears the solenoid plunger rod is longer than that used with the Sportster 1.2KW stock model starter.
