electric governor on a MEP-831a

[gstirling]

First a thanks to Kurt for hitting the nail on the head in a PM. Pin the set and it runs fine.

Now the new issue. my 831A appears to run perfectly on the mechanical governor, starts, takes load, rejects load, no-load etc... perfect as long as I hold the electric governor off. once I let the electric governor try and take over, the gov. pulls the throttle linkage over to the magnet, engine bogs down, then one of two things can happen. it either trips the over current protective relay and shuts down the engine or it gives it full throttle, then pulls it back to the magnet (surging), then the unit shuts down on overcurrent. Since it runs fine (no overcurrent issues) when on the mechanical governor I'm pretty certain there are no actual electrical issues (no actual over current or short circuit).

So here's the question - how/can you "test" the electric governor? is the electrical governor something that can be "repaired" or is it a replace only part? (I did open the cover and its clean and linkages move freely) or can the linkage be so out of adjustment that is the issue?

If it could be the linkage is there a TM on how to adjust the electric gov. linkage. don't remember seeing any info in the 9-6115-639-13&P TM I have. If I missed (have looked) a previous thread on this topic please point me to it.

thanks

If you go to the TM forum, (generator and electrical TM's) page 2, top thread, you will have what you asked for.

If you can't get it adjusted. Kurt sells a very nice controller for a very reasonable price that doesn't need any adjustments at all. I highly recommend them.
