My 12kv was running...

My 12kv was running for an hour and it shut down, now it starts and runs only for about 20seconds and shuts back down.

Mechanic's Assistant: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?

Full tank (250gal.) of propane and all valves are open

Mechanic's Assistant: Do you plan on doing the work yourself?

Yes , if all possible

Mechanic's Assistant: Anything else we should know to help you best?

Unit has about 1 hour total time on it, I started it up at random for about 1 year or so with out any issues.

I have already paid a total of $42.00 and have nothing... do I need to pay every single time you guys contact me without the possibility of any solutions to my problem?
Technician: Hank F., Technician replied 11 months ago

I am still waiting for the serial number.

For billing questions, you need to contact Customer Service - I am just a technician.

Technician: Hank F., Technician replied 11 months ago

Ok.

This is an old Generation I unit.

There are a series of 5 LED lights on the control panel.

Which LEDs come on when the genset shuts down?

Ask Your Own Small Engine Question
Customer reply replied 11 months ago
it flashes all lights when it starts to shut down, I have checked the oil level and it is all good, air filter is new and the gas regulator is one year old. I disconnect the load and everything and it makes difference.
Technician: Hank F., Technician replied 11 months ago

All the lights flashing indicate that the exercise timer is not set.

While the unit is running, is it running smoothly, or is it surging?

Take voltage and frequency readings directly at the circuit breaker while the unit is running for 20 seconds.

What voltage and frequency readings do you get?

Customer reply replied 11 months ago
No power at all.
Technician: Hank F., Technician replied 11 months ago

Ok.

I have uploaded a series of tests for you to do.

Please do Test #4 - Fixed Excitation/Rotor Amp Draw, and let me know all the results.

When giving the results, please give me wire numbers, not step numbers.

IE - say "wire 2 to 6 is 35VAC", not "step 5 is 35VAC". This makes is easier for me to reference and analyze the results.

Sorry, I have been away from Home helping with Hurricane damage control, I will be back home this coming weekend and will see if I can perform the test you requested. quick question... are you starting to thing that the regulator might have gone bad?
Technician: Hank F., Technician replied 10 months ago

I've been down in Texas on a hunting trip, and just got home late last night.

The VR is definitely a possibility, but there are several things it can be. I am not even going to venture a guess at this point, until we see the results of those tests.
