You can take it to a battery place and they can test it under a load.
This procedure is covered in detail in the proper manual for your model
check for stator AC output first, check specs for your year, that has to work properly under load to go any further, then check for 12.75-13.50 VDC at the battery with it running, if it tests OK at the stator plug and shows battery voltage dropping instead of climbing at fast idle, suspect the rectifier/regulator It is impossible to test the rectifier, but it is built into the regulator/rectifier and you can test the regulator. Buy a manual!
Use an ohmeter to test tesistance where the plug wires connect to the coil-it should read 12,000. now for the the primaray side where the signal wires connect to the coil should be 2-3 ohms.
Unplug your voltage regulator at the front of the crankcase on the primary side. Use a multimeter set to "AC", by inserting the probes into the two holes and rev your bike to about 2500rpm or so. You should get about a 40-60 volt reading. You should also check for a ground, by doing a continuity test, or use the OHM setting on your multimeter to make sure the stator is not grounding out. If everything is good there, and your not charging up, your regulator is bad.
The starting price for the 2013 Harley-Davidson Heritage Softail Classic is $17,599. This price is for the vivid black color only. One can go to the manufacturer's website to search for dealers near them or to arrange a test ride with a local dealer.
To test the charging system on a 1994 Harley-Davidson FXR, start by checking the battery voltage with a multimeter; it should read around 12.6 volts when fully charged. With the engine running, measure the voltage again; it should increase to about 13.5 to 14.5 volts, indicating that the charging system is functioning correctly. If the voltage remains the same or decreases, inspect the voltage regulator, stator, and wiring for any faults. Additionally, check for loose connections or damaged components that could affect the system's performance.
To test a stator on a Ski-Doo, first, disconnect the electrical connectors and use a multimeter to measure the resistance between the stator's windings. Check for continuity between the windings and ensure there's no short to ground by measuring resistance from the windings to the stator case. Additionally, you can test the output voltage by starting the engine and measuring the AC voltage at the stator's output wires, comparing it to the manufacturer’s specifications. If the readings are outside the specified range, the stator may need replacement.

nope....stator as in the alt? dont do it. this was a test before the computer days... you will surge/ zap the comp. or did you mean starter? either way the answer is no
yes for continuity
To test a Polaris stator, first disconnect the stator from the wiring harness and use a multimeter set to the ohms setting. Measure the resistance between the stator's terminals according to the specifications in the service manual; typically, you should see a specific resistance range depending on the model. Next, check for any shorts to ground by testing each terminal to the stator housing; there should be no continuity. If the readings are outside the specified ranges or if there’s continuity to ground, the stator may be faulty and should be replaced.
