Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello, my name is ***** ***** I am going to assist you with this.
What type of equipment is this/
That's ok. I am certified an all Generac air-cooled units up to 60kW. It doesn't matter if is a portable or a stand by.
First. lets see if we can do a simple reset.
Turn the switch to OFF.
Pull the fuse out of the control panel, and wait 10 seconds.
Put the fuse back in.
Set the switch to MANUAL.
Will the unit run now?
Also, by doing this, you will need to reset the exercise timer, as removing the fuse will erase the memory.
You need to connect an AC voltmeter to the back of the circuit breakers, and start the genset.
How much voltage is it producing for the few seconds it will run?
I need to know the voltage output - that will tell us where we need to go next.
You can do it when ever you are able. There is no time limit on this.
But be advised that I work 2 day jobs, and normally help on Just Answer in the evenings. Tomorrow I have my long job, and work 6:30 AM to 7 PM, and won't be able to respond until tomorrow evening.
Not a problem at all.
You need to test on the input (generator side) of the breaker.
This rules out a bad breaker, and everything past it.
There are 2 wires on each breaker. One is the input from the stator, the other is the output to the transfer switch.
You need to be testing the stator input side.
There are 8 wires that come off the stator.
The 2 large black ones that go to the circuit breakers are numbered 11 and 44. The 2 large white ones that go to the neutral bus are numbered 22 and 33.
The other 4 are small control wires that go to the engine to control connector.
I have uploaded as series of tests for you to do.
Please do all of the steps in Test 4 - Fixed Excitation/Rotor Amp Draw, and let me know all the results.

Have you done the tests yet?
There are several things that can set the code. Testing is the only way to find out what is causing it.
There is no such thing as a magic cure.
