The most common problem is the capacitors blowing. This is the round (usually white in colour) barrell shaped device usually found in the end cap of the alternator. It will have two wires attatched to two of four pins. I would advise that you check the voltage at the end of the alternator first to eliminate a wiring problem. The capacitor can only be tested with the correct equipment but changing it should solve your problem- 75% sure.

I had the same problem on my Powermate 525500 (5500 watt) and finally manage to get in contact w/Powermate (PRAMAC) tech support. He told me that if the gen is setup for a while, the exciter loses it's magnatism. To reenergize ( jumpstart) as he called it, follow the prcedure below. Probably not for amatures.
1. start up the generator.
2. Pull off the brush cover on the end of the gen.
3. Get a 6-12 volt battery and setup w/color coated cables.
4. place the negative lead on the left side brush terminal and tap the right side brush terminal w/ the positive lead.
5. Wala....you sould have power.
One would think that this important info would be on the manual or a blog somewhere.
Good luck and have a wonderful day.

SOURCE: Hello I have a coleman
I can't get a wiring diagram or a manual without the model. type, and code off the engine.
What I can do is describe the usual wiring and see of that helps.
The ones I've worked on have a very simple wiring harness,
a black wire runs down into the front of the engine, this is the kill wire that attaches to the ignition module (coil), the other end of the kill wire connects to the center terminal of the on/off switch.
A white wire runs from the switch to the oil shutdown module, at the switch it's connected to the terminal that's closed when in the run position. The other switch terminal connects to a wire that runs to the frame ground. The gray wire from the oil sensor module connects to the oil sensor on the side of the engine.
That's pretty much all of the wiring there is for an engine that doesn't have electric start.
Rate me please,
Carl

Hello;
Take a look at your outlets. Some of these units use pretty cheap outlets and short out. You will know if it is bad when you look at it. Hope this helps.
Thanks;

The voltage regulator controls the output. You will need to check that first.
