Kohler 12 kW Emergency Power System - 12RES-L - Answered Questions & Fixed issues
Starter battery will not charge
Hi
If the starter battery is not taking a charge, then it may have failed and require replacement. It is not uncommon for a battery that sits on standby for long periods of time to eventual fail. Best approach is to contact Kohler direct or one of their service agencies to get the correct replacement battery for the generator system.

My kohler 12res starts but governor moves constantly which makes my voltage erratic
this is a common complaint to these , what it boils down to is allways a fuel problem , if its gasolene then its in the carb if it's nat gas then it's in the regulator/vaporizer you'll have to clean these items to see if that helps . someof those liguid cleaners sometimes works but i find a good dissassembly cleaning to be the best

Kohler 30RES Generator LOC code coolants ok
How old is the 30RES? unplug the low oil sensor on the radiator and see if it runs, they are notorious for failure and have to be filled in the radiator to the brim. If it runs order a new sensor, I have replaced many of them for this reason, but more often the radiator seems full by dipping finger in, but will always take more coolant. The sensor is mounted so high up in the radiator. I ask the age as newer ones require a signal to be maintained and it isn't just a simple ground if low on coolant, if it has 3 wires then disconnecting for the above test will not work

Problem with kohler 12 kw, showing 38 . 1 code
Normally fault codes are letters? I am not familiar with that code at all. You may have got the control in some configuration setup code 3P0(X) is for raising and lowering the voltage where X is a number from 1-9 for increase

No 110 ac power out of gem
Check the rotor slip rings for tarnish as it has sat.If they are clean, the rotor may have lost it's magnetism and may need flashing (putting DC power directly on it for approx 3 seconds) with brush wires disconencted POLARITY IS CRITICAL

How do you check the slator to see if it is any good useing a multymeter
You must first disconnect ALL the stator wires to prevent a bad reading. You MUST have a good meter, cheap ones will not do. Put the meter on Ohms and put the probes together, note reading (this is the resisitance of the meter wires and this reading will need deductiong from the test readings). You will need a service manual to know what that actual values should be at what ambient temp. They are normally very low less than 1 ohm so cheap meters won't read. Check each wire with one lead and the other to the stator metal ground. You should have ZERO any value here is a short. Then check between each pair and read the value (many stators have multi windings T1,T2, Q1 Q2, B1 B2 etc, so you need to make sure you measure across each pair.. Generally values are 1 ohm or less

I have an older Kohler Power Pro 5000kw generator
try contacting Nixon Power Services in TN. If they cannot help, you take the old rectifier out, note wiring. A rectifier is nothing special as long as it is the same current rating, if the part is truly obsolete then a good electrnic supply house can give you an equiv
