What is kohler generator engine fault code 0094-01 means?

We bought a koher generator last 2011 with serial number 2016049957, i just want to ask how can i fix the engine fault code 0094-01 because this fault stop the engine, we already add coolant but the problem still coming after we run the generator for quite sometime, before we are not experiencing this problem only recently we encountered this problem. Can you please help me solve this problem?. Thank you.

SOURCE: i have a kohler rv generator that will start .

When this happens, this usually means that your genset is not creating voltage. First thing I would do is disconnect your remote start wire from the genset, this will eliminate the start switch inside the RV. For a shorted remote start switch can cause you genset to shutdown. Second, place a volt meter at a spot where you will be able to read genset voltage. If no voltage is available and your voltage regulator is new, then the problem is with either the rotor or stator. The rotor is the easiest check. You need to reach the brushes. Take a resistance reading, which should be around 20 ohms. Clean the rings and make sure there is enough length on the brushes, at least over 1/2". Next, flash the fields using a 12Vdc battery. Use rubber gloves when doing this. Place the positive side to the ring closest to the bearing and negative goes to the back ring. This is done while genset is running so be careful with rotating parts. Have a volt meter on the output wires. Once you flash the fields the voltage should increase to over 50Vac. If it does then your stator is bad since you installed a new voltage regulator. If the voltage does not increase when flashing, then the rotor is bad.

Can't search for a manual without model, type, serial, etc numbers...

A few things to take a look at:

1) Oil level / pressure sending unit. This is normally bypassed as long as the start switch is pressed. When engine starts, and switch is released, engine will die if sending unit is defective, or you are low on oil.

2) Exhaust temperature sensors. Older units were notorious for burning these up.

3) Cooling Water Temperature sensor. These cause trouble often, but mostly due to water pump impeller being eaten away by galvanic action and not able to pump water as effecively. End result is water temp higher than normal, which trips the switch, which kills the engine.

4) Alternator (generator) output not as it should. If output doesn't rise to proper level within a few seconds of engine start, the engine will be shut down.

5) Choke not working as it should

6) Bad fuel, bad fuel pump, clogged fuel filter.

SOURCE: my 3.5 kw kohler marine

Check that when you run it, it is not in fact making correct voltage (within about 10% is good), also make sure the engine is coming up to full speed, 3600 or 1800. You could check this with a multimeter that measure hertz. On the main output leads when the genset is running make sure it is getting close to 60 hz. or if you are in an area that uses 50 hz. check for that respectively. There are a couple things that would affect this, one would be your SCR module. There is a test procedure for this which you could find here. http://www.scribd.com/doc/50171916/tp6196-1 . I don't work on marine units, mostly standby so these manuals are for residential. Check your fuses, could even go as far as checking the wiring in the back and wiring and condition of the brushes and sliprings. These actually build field voltage to make 240 or 120 volts whatever your unit is configured to make. The brushes need to sit flat on the slip rings and on a unit with 10 hrs. the sliprings I can't imagine would be very dirty but check that as well. If you have an ADC2100 controller use this manual to go into the controller to verify that it is set for the correct voltage that the machine is built to make. The only other fairly simple thing to check that I've had issues with is if Kohler mounted a fuse block on the side of the cabinet mounted to the genset with no vibration isolation. Check these fuses while attempting to run the unit and make sure you getting steady voltage out of them as sometimes they will vibrate causing pulsed voltage to come out of them and can give you an intermittent UU, UF, or OC fault (undervoltage, underfrequency, overcrank).

SOURCE: generator quit working

I have fixed Dozens of generators and around 70-80% of starting- none running problems are due to either A) Debris soil dust or Water in the Carb (don't ask me where it comes from but it gets through or B) Jets blocked with same or just Electrolytic Crud, dissimilar metals Brass Jet in Allot Carb etc. First step drain tank & carburettor bowl (screw or bolt in bottom usually, run a needle or similar though the main jet (up in centre in Honda type designs) when sure all is clear, fit a $1-$2 small paper in-line fuel filter and try again. The standard filters are too coarse and let in fine dust-rust all the time, hope this helps always works for me, Good Luck from England!

Hi Jesse,

I didn't have a model / serial number to try, but I suspect the date you're looking for is coded in one or both of those numbers. Have a look here & plug the requested info in to see if it returns the info you're after. Good luck!

I have a Kohler 12.5 KW marine generator on my houseboat that has a problem I was hoping you could help me with. Specs: Kohler 12.5 KW 79 CID 23HP Mfg date 9-10-96 Gen Engine Serial # 06919 L-29-R


there are some magnets behind the flywheel to cause the battery charging system to recharge the batt. sometimes they come unbonded/loose from the flywheel and cause the engine to become hard to turn. I would start there first.
