+ | **Three tests to bench test the solenoid, text and video** ... ((IronMick of the XLFORUM https://www.xlforum.net/forum/sportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/ironhead-sportster-motorcycle-talk-1957-1985/140741-how-to-bench-test-a-solenoid-pic-vid?t=1525907)) \\ | ||
+ | **To test the pull-in coil**: | ||
+ | - Insert a deep socket part way into solenoid. | ||
+ | - Connect battery -ve to the large short stud of the solenoid (normal output to starter motor). | ||
+ | - Momentarily apply +12 volt jumper wire to the small terminal of the solenoid (normally from the starter relay). | ||
+ | - The socket should pull in. \\ Leave it pulled in to test the hold-in coil. | ||
+ | **To test the hold-in coil**: | ||
+ | - Move the battery -ve jumper from the large short stud to the solenoid case. | ||
+ | - Apply +12 volts to the small terminal and leave it connected. | ||
+ | - Try to pull the socket out of the solenoid. \\ The hold-in coil should resist your effort to pull the socket out while +12 volts is applied to the small terminal. | ||
+ | - Remove the +12 volts from the small terminal. \\ The socket should slide easily back out of the solenoid. | ||
+ | |||
+ | **To load test the high-current contact plate of the solenoid**: \\ | ||
+ | A headlight bulb works well for this. | ||
+ | - Jumper from batt +ve to to +ve of light. | ||
+ | - Jumper from large long stud to -ve of light. | ||
+ | - Jumper from batt -ve to large short stud. | ||
+ | - Manually push in the plunger. \\ The bulb should light up. | ||
