Its on the end of the rotor. Letting them idle is a killer for the voltage regulator circuits. You should fire them directly to operating RPM. No idling.

How long did it run at low rpm? I do think you need to dig into the rotating rectifier.

Can you tell us more about what the generator was doing when the magic smoke came out? Was it idling or was it up to speed? Was it connected to a load and making current?

+1. There are some reasonable options for a full featured instrument that won't kill your wallet.

Need to troubleshoot the rotating assembly on the exciter.

When you held the START switch did you see the needles jump at all?

Have you measured the output of the generator terminals or the convenience outlet to check voltage and frequency?

I highly recommend getting a meter with a frequency readout. There are a number of measurements that will require it. You shouldn't trust the HZ readout until we know what is going on with the governor. One reading you can take with a normal voltmeter is the exciter voltage. Those are...

It will be a digital pulse train.

The magnet pickup does go to the governor module. According to the electrical drawing its on terminals (16) and (17).

On page 141 of the TM is the pinout of the diagnostic connector. I think most of what you'll need to test is there. I'm looking in the manual now to see the first thing to test. Lets see if we can get you a RPM test doable with what you have.

If you have a HZ reading on your Voltmeter you can check the frequency. HZ is RPM on these generators but when they are run too slow they can't generate enough current on the exciter. The bonding jumper wont be the source of this problem. First check your RPM if you can and then lets figure...

Do you have the TM? The troubleshooting section for the governor starts on page 227. Give this a look and see if it helps. I'm going to look up the module number and see if its like the ones I've worked on before...

It is OK to dump a full load on it at once. That is actually one of the tests you should do to ensure it is fully functional. Obviously after its warmed up sufficiently. When I do my monthly runs I've been connecting the MEP to the house and running the water heater, oven, and dryer at the...

Sorry, I totally read that wrong. You are right. Its not in spec. What is the mechanical governor set for?

All that seems good. Can you describe how the governor acts when you shut it down? Does the actuator close against the magnet?

We bottomed out about zero which is not at all typical for central NC. I've been working with neighbors already this morning to get pipes thawed. One of the things you can do once its running is to give the governor arm a little shove and see if the controller responds to keep the RPM at...

Does it run smoothly otherwise? Do you have a volt meter with a frequency readout?

You can get it here. http://www.steelsoldiers.com/showthread.php?135020-TM-for-MEP831

I have some thin plastic cutting boards I was thinking about using. They may be a little thicker than a drum head. How much gap do you think there is between the stator and rotor?
