That sounds just about right, if the relay contacts get welded together it sometimes takes out the driver on the printed circuit board. As you found out, 12vdc from 23 to 194 makes the transfer switch move to the Generator position, relay not energized makes the ATS move to the Normal position.

You can make a nice test function by installing a 10 amp contact switch in series with either the N1 or N2 terminals. When the switch is open the generator thinks the Normal power has failed.

Carl

1. Does the generator stay running when you start it the first time?

2. What color is the housing on this generator? Try to get the model number and serial number.

If the genset is shutting down on the first try, then your probably not creating voltage. However, if this is an older unit then the genset may stay running although no voltage is created. Place a volt meter on the genset to check for output voltage.

SOURCE: Generac 4456 does not start on power loss

I install and work on these everyday. If you hooked up the transfer switch you probable have a control wire wrong. check the utility power sense wire. That lets it no when to start in auto. it could be a relay or fuses. or a control board.

First start up


Try disconencting the remote start wires between the transfer switch and the generator, if ot still does it you have a bad control board. If it stops, then check the transfer switch for correct wiring of utility and generator power wires, also check with an ohm meter if the run contacts in the transfer switch are closed, that would indicate loss of sensing, or bad board

Kohler automatic transfer switch RDT CFNA 0100B. I can set it to exercise and it will do so for several weeks then it forgets. No fault shown.


Product manual does not have troubleshoot section.
The operation might be normal, and within expected parameters, or it might have a glitch.
Suggest you contact Kohler Power directly:

Is there a fault?? All UL listed generators including Kohler are required to lockout on a fault on shut down. This really sounds like a problem with your 2-wire auto start connection between your automatic transfer switch and genset. RDT model automatic transfer switch it is the 2 middle wires on the green connector and terminals 3&4 in the generator. close to run and open to shut down. Any open at any time will cause the unit to shut down. The 12 will shut down instantly upon an open because your 5 minute cool down is built into the transfer switch.

I have a Kohler 25kw that runs on LP that will not stay running. When you switch to manual start, it will run than shut back down like it is not getting fuel. The LP pressure at the regulator is correct.


If you are sure the regulator is ok and that the engine is getting the correct amount of fuel, then check for any throttle linkage issues, high speed fuel adjustment settings, loose carburetor mounting bolts, air/vacuum leaks, etc.

Also check to see if the engine has oil pressure cutoff, low coolant cutoff (if water cooled), and overspeed control.

Also, does it transfer and then shut down or will it even transfer? Make sure the transfer switch is ok and there aren't any issues with loads, etc.

Need circuit diagram for Kohler ATS part # K163341-800


Do you know the part number on the board. Kohler used numbers written with permanent marker on their controls boards. They usually started with a letter like A or B.

You might have a * 297373 or *297375. They usually had a big orange relay that stuck up in the middle.

The filter capacitors would always dry out over time and relays wouldn't energize correctly.

Depending on the board we might have a drawing.

We fix some of the older style. Check out our website: www. flightsystems.com. You'll find contact info. For fast response call in and be prepared with any board numbers you might have found!

My Kohler 17RES has stopped doing it's scheduled weekly exercise. How can I get it exercising again?


On your Automatic Transfer Switch ( the little gray box you see on the right in the picture above) you have two blue buttons. One is a Manual test switch. The other has a clock on it and this is your exercise set button. Hold it down for a FULL 3 seconds if you want it to excercise without a load (not powering your home) Hold it down for a FULL 6 seconds if you want it to exercise with a load every week. Your generator will start and run for 20 minutes, and then shut down. Now every week your generator will exercise at the time and day that you pushed the set button.
