This is the terminal from / to the battery with engine off it should read static battery voltage, with the engine running it should read anywhere from 13.6 to 14.2 volts

SOURCE: kohler ch730s runs but battery dies while engine

you may be correct...to verify that the stator is working, you can disconnect the two either white,gray,or yellow leads that go into the regulator/rectifier.these come off the stator. You will need to use a multimeter set to "ac" to check this. Set the meter to read at least 100v ac. them ,while engine is running, check the voltage on these leads...should be around 30VAC..If this voltage is present then you can rule out the stator.

Alternator not charger


not know what engine you have a briggs has a coil mounted under the flywheel with a diode a kohler has a col under the flywheel and a voltage regulator so with a briggs see if there is power when running before the diode and a kohler see if there is power going into the regulator

Getting NO power from the MR2 160/2 Mecc Alte Spa altenator stator. Generator repairman said he didn't find anything wrong using his voltmeter. Measured 6 vac out. I tested caps and they seem good....


There are a few more components to check in the system. From the information provided this is not a Kohler generator as Kohler makes all their own AC alternators under 350KW, seems you may have just a Kohler engine (probably a CH25). Cannot find any info on the voltage regulator which leads me to believe it may be integrated into the main controller. Curious to know who the manufacturer is. If the capacitors are good, try checking the diodes. A volt/ohm meter with a diode check will do. Voltage reading on one side and nothing on the other. If you have no access to a diode check feature, try reading it through a battery NOT SHORTED TO BATTERY hook a meter to a battery and put the diode between one of the leads to the positive, one way will read voltage the other will read open, no voltage, or OL. Look for any fuses or breakers blown / tripped. 6 VAC on the output is about residual voltage meaning voltage the alternator makes without any help from a voltage regulator or field voltage. This usually means the alternator / rotor windings are still good. This alternator is brushless so you could seperately excite this unit via a 12V battery through your field. Look for your exciter field winding, it should have some kind of label on it saying F+ and F-, apply 12V here momentarily on + & - respectively with the unit running and you should see your output voltage spike. This tests the alternator. If this tests ok, then check to make sure your wiring / fuses from the alternator to the controller or voltage regulator (voltage sensing leads) are ok. If all these check ok, it is likely you have a bad voltage regulator.
