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
Almost always bolted to the front of the frame.
unplug the regulator take a test light tough the tips if the light come own your reg
is bad !
wheres the voltage regulator in 2002 katana 750cc
How_do_you_check_your_voltage_regurlator_on_your_motorcycle
A charging system test is done to check the internal voltage regulator. It can be done at any auto parts place.
with a regulator tester kohler sale one that will test most regulators
with a kohler regulator tester
You need the test equipment and a bunch of knowhow.
With engine running, ensure system voltage is in the 13-14 volt range.
it is inside the alternater, not stand alone.
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!
You will need to go to a repair shop and have them test the charging system.
have the battery checked and test the voltage regulator
Voltage regulator a loose connection. Look around the switch. No loose wires or corroded terminals? Get a new regulator and put it on. Really the only way to test it on older bikes.
Test/replace the voltage regulator. The year, make and model info would help.
