Have you done any troubleshooting yet? Do you have the technical manuals for the set?

As Light in the Dark indicated, download the Technical Manuals (TMs) from the forums TM section.
Specifically, you need to perform the AC Voltage Regulator tests called out in the TM ending in -24.
Post up the results of each test step and then we can guide you toward finding the cause.
Be sure your generator has the "Fuse Mod" installed.
It's the fuse holder and fuse on the left of the AC Voltage Regulator

I have done some testing. I have the manual as well. Thinking someone may have had this problem. I've tested the power coming out of the generator itself and replaced the AC circuit interrupter relay. Tested a lot of circuits for continuity etc. The generator only has 80 hours on it. Also I tried exciting it with 12 volts.

Indeed, several people have had this same problem.
The results of the AC voltage regulator test will tell us where your issue lies.
You can also search this forum and read other people's stories with similar issues, including most recently:
There are a few reasons this can happen, that's why the VR test results are needed to pinpoint the root cause.
We also need to know if your gen has the fuse mod that Kloppk indicates above, and need to verify the fuse is good.

803A Troubleshooting
Hey all, I'm the new owner of an 803A, and having some issues that I can't seem to solve-- or I'm too cold and defeated to think straight. 1600 hours on the clock, has fuse mod. It took me two days to get the engine running. New fluids, filters, ect. Pulled the injector pumps, cleaned...

And I would add the MOV, if yours doesn't have it already. (The blue item in @kloppk's post above.

Is the 24V on all legs or one?
On 240 Volt single phase its 24Volt AC on both 1 and 3 terminals. I've ordered a new voltage regulator(the aftermarket one). I found that the adjustment screw on the potentiometer has been sheared off. Ill see what happens after the install then post what I find.

Okay, the reason I asked was I have seen two times where if it is one leg, the wire broke inside the crimped connector insulation cover behind the output lugs. It is basically arcing in there & causing reduced VAC output. You won't ever notice it until it lights on fire or you remove the output panel and pull really hard on the wire. The insulation is stiff & holds the wire in place. I guess moisture sneaks in & corrodes it.
Kurt makes great products, you will be happy with his VR!
