TROY-BILT PROBLEM WITH KOHLER COURAGE SV730 ENGINE

It seems kohler engine is well aware of the problem they have in the field with their engines. They told me since it didn't discharge the battery in one night to do as the manual states, disconnect the battery if longer.

Kohler Generator has a noEc error code


My 11 month old Kohler 14RESL stopped working sometime this month. The GFI outlet to the trickle battery charger tripped and the battery charger went dead and so did the battery. When I realized the GFI had tripped, I reset it and the trickle battery charger started recharging the battery overnight. In the morning I tried to start the generator by pushing the run button - nothing happened except a message 'noEc' appeared on the status screen. I called Kohler and was referred to their local distributors. After a whole day of phone calls to many distributors, I finally found one, Kraft Power, who would come out on an overtime basis and fix the problem. I chose Kraft Power because they were the only company who knew what 'noEc' meant. They told me that since the generator had lost all power (no trickle battery charger), the engine had lost it's configuration! I have worked in the technical field for 25 years (computers, networks and remote diagnosis) so this answer was particularly troubling. THIS SHOULD NOT HAPPEN. The technician had to connect to the port on the controller, bring up Site Tech on his laptop, and enter two pieces of of information into the configuration. 1) 14RESL and 2) the engine type. We had to use a mirror to read the engine type as it was under the oil filter!

I have 16 hp Kohler engine with a compression release not working,help.


i have a Kohler 16 Magnum opposed cylinder engine and it wont crank over with the spark plugs in it,battery and starter are both good,its an aluminum engine and i have seen several of the Kohler engines break the automatic compression release on the cam gear and they seem to lock up while trying to start,pull the plugs and the crank fine,Kokler is the most expensive engine i have seen and their parts are outrageously priced,old Kokler was a good engine,newer ones in my opinion are junk,i work at a small engine shop,i have seen new Kohler engines with a broken ACRs,i work at a second job,we got a new supervisor that worked for Kohler before her came to our plant,he said he worked customer service at Kohler and he heard complaints constantly from people using their engines and the returns were out the roof on their engines,what im saying is i wont ever but another Kohler unless itsm an old one,Thanks Tommy

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. Maybe rectifiers (2) in armature? Can I flash the coils? New generator is $900 delivered.


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.
