+ | A typical well-made solenoid as two windings connected to the small terminal. ((Oldwrench of the XLFORUM http://xlforum.net/forums/showthread.php?t=522413&page=2)) \\ | ||
+ | One coil goes to solenoid case ground and the other goes to the big starter lead. \\ | ||
+ | When you hit the starter button, battery voltage goes into the solenoid, through the 'PULL IN' windings to case ground, and that pulls in the plunger. \\ | ||
+ | When the plunger pulls in, it brings the contact disc in contact with the big battery and starter terminals. \\ | ||
+ | When that disc connects with the starter terminal, it shorts out the PULL IN windings and applies voltage to the HOLD IN windings to reduce drain on the battery. \\ | ||
+ | If the battery cable is connected to the starter terminal of the solenoid, then the hold in windings will be conducting current. \\ | ||
+ | That current isn't strong enough to allow the HOLD IN windings to pull in the plunger but the current flow is enough to make the solenoid get really hot. \\ | ||
+ | And if not disconnected, it will burn both the PULL IN windings and the HOLD IN windings because they are wound together inside the solenoid. | ||
+ | So you don't want to hook up the battery to the terminal used for the starter. \\ | ||
+ | The solenoid will still work at first, but left connected it will burn out either or both of the windings because the HOLD IN windings are constantly conducting. \\ | ||
+ | Using an ohm meter would give really confusing readings because you'd see continuity to both case ground and the starter terminal from the solenoid windings connection. | ||

+ | 67 and Up XLH Starter solenoid (71469-65) \\ | ||
+ | Below, the 1/4" solenoid mounting threads were stripped (nut on the top bolt) so they were tapped out for 8mm cap screws. ((photo by sifty of the XLFORUM http://xlforum.net/forums/showthread.php?t=1592463&page=27)) \\ | ||
+ | 8mm x 1.25 threads have almost exactly the same thread pitch as the original 1/4" thread. \\ | ||
+ | Then the mounting bracket and and spacer were drilled 8mm and the solenoid was installed using allen head cap screws and spring washers. \\ | ||
