Question about Kohler Generator 30 Kw Nat Gas Or Propane Indoor

1 Answer

What is the most likely cause of an Auxiliary Fault on a Kohler Generator (Model 30RZ62)?

Does anyone have a service manual for a Kohler 30RZ62 Generator with troubleshooting the fault codes?

    I read from another post that it could be the low coolant level switch. So I disconnected the switch and started the generator manually. It ran for about 10 mins, and I reconnected the switch. The generator faulted out with an Auxiliary Fault. Therefore, I am going to purchase a new switch. I believe this is the issue.

SOURCE: Kohler 5E generator on my boat got wet there is no

  1. First you must clean it all, especialy the generator, windings, AVR etc. if it was wet with sea water (better do it with fresh water or electro-clean, than other liquids). Then you should dry it well (with a hot blower) for about, but not less than 24 hours, before starting.
  2. If you already started it wet, or it got wet while running, you may have some parts burned, with low insulation of cables, windings etc. Check the AVR, rings and brushes (if any) and other electronic boards for visualy burned elements or check the semiconductor elements (diodes and transistors) for proper qualities.
  3. You should check the gen. windings insulation resistence to hull (gen. iron) [all stator and rotor windings]. It should be more than 100 kOhm in order to let you start the generator motor.
  4. When dry and clean, with no burned elements you can start the engine. If it reaches its normal speed - measure the voltage on generator terminals, if it is OK check the connections (breakers, fuses) to the distribution panel. If it is very low under 30 V AC, the problem may be in AVR (Auto Voltage Reg. - Field DC supply)
  5. If the voltage is under 10 V AC, you may need to recharge the magnetic field with a 12 V battery connected shortly to field terminals - +/- respected.
If you fulfil these instructions and you need more help, please ask as an answer to this solution or on my e-mail: parlapanov@yahoo.com.
Please give some information about your generator: is it 5ECD, 5EKD or some other - then give some more details about it.

SOURCE: I have a Kohler 12RESM1 propane generator with oc/uu code

I am getting the same exact problem and errors with my 12RES Kohler generator. It will try to start using a remote switch but fails. Then it will start using the switch at the generator. The error code it comes up with using the remote start switch is usually OF or UU. It is less than a year old. Can Kohler Help??? Dave R.

Aux fault can be many things, if it failed to start you may get it. Try reseting and manually starting. See if it re-occurs while it is running or does it ever start and give error. I have seen this generator by a coolant level sending it is an auxillary fault
