Best Answer

Usually the voltage supplied to your battery when the engine is running is about 13.5-14 volts max. If the output is higher or lower than 12 volts, then the regulator could be faulty. hope this helps

How do you test a rectifier for Harley Davidson motorcycle?

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!
