Hey everybody, I have a 99 sportsman 500. Just replaced the stator, & flywheel after one of the magnets let go & destroyed my stator. The machine starts & runs good, but I am not getting the kind of voltage at the battery that I should. I think the problem is with the voltagage regulator. I need a simple way to test the regulator, because the manual leads me thru a series of tests that require a "peak reading" meter which I do not have, I'm using a Fluke 334. Any help will be greatly appreciated !!

 

If your stator is putting out AC voltage, above 7 volts at idle(which it should be since it's new) Check fot 12 dc volts on the red wire to the regulator. If it has 12 dc volts, replace the regulator. Check the terminals at the regulator also, they have had corrosion problems over the years.

The peak reading adapter test is for the ignition system, not the charging system.


Alternator Output Test (AC amp)
This test measures AC amperage from the alternator.
Maximum alternator output will be indicated on the
meter. It is not necessary to increase engine RPM
above idle.
Place the red lead on the tester in the 10A jack.
Turn the selector dial to the AC amps (A) position.
Connect the meter leads to the Yellow and Yellow/Red
wires leading from the alternator.
Start the engine and let it idle. Reading should be a
minimum of 7A at idle.
CAUTION: This test simulates a “full load” on the alternator.
Do not perform this test longer than required to
obtain a reading or the alternator stator windings may
overheat. 10-15 seconds is acceptable.

 

Thanks bro, turned out it was a corrosion issue, The two pin connectors( red & brown wires comin from the regulator) that plug into the harness in the left wheel well were not making contact, due to all the corrosion... Have a great day !!
