Default Kohler 3A21 Electric Plant

We got the generator running using 24 volts and applying a load. That worked as it should. However it did not produce 115 volts. Without a wiring diagram I am lost. Can anyone help me?

I have since found that It is producing 119 volts but not at the normal hook up terminals.

Does this look even close. Units were very similar back then

I appreciate your effort but it looks a lot different. I have one switch (high and low) and no gauges. Thanks for trying.

I have the automatic version of the 3A21. I found a PDF of the manual for it on the web using google that has a couple wiring schematics in it along with an explanation on how the generator system works. Scroll to the bottom here: http://www.oldengine.org/members/frank/kohler1.htm

A few pix of mine are here: http://images.ttyr2.com/index.php?di...Electric Plant
