Portable generac generators

I need to know how to check a portable gas generator electrically?
The unit is only putting out about 3.5 volts. The breakers and connections are all good. I'm being told that the rotor is bad. How do you test this? But I was also told that there is a thermistor that may be bad. Where is this located? It's a Generac 5550 watt generator. Hmmm?
If you are asking here, you do not have the needed expertise to make the repairs. Take it to the nearest Briggs and Stratton service center and have it serviced. I have one that has lasted more than 25 years and it is getting some parts installed tomorrow. I have more than 50 years in the electrical industry and the problem you describe needs an experienced generator electrician to repair it. As to just what is wrong, it can not be diagnosed on line without many tests. You need at least 2 different test meters, and a complete wiring drawing.
The thermistor would be located in the windings or on a circuit board on the exciter coil of the generator. Some of the generators need to be flashed in the exciter circuit to start the cycle. This is also something that only experienced personnel should attempt.

Generac 5500 Generator????
Does ANYONE have an opinion on the Generac 5000 or 5500 portable gas generator? I was wanting some reviews and does ANONE know a cheap place to purchase one? I've seen people buying them at Home Depot in the past 6 months from $299-$519 but the cheapest I've seen is $689 from Electric Generators Direct.com. THANKS
I had a Generac 5500XL generator. Nice machine, but it had problems starting my deep well pump. The engine would surge several times until the pump was running, causing severe voltage drops and brownouts. It really wasn't suitable for my use.
It was replaced with a Briggs & Stratton 5500 watt generator with higher surge current capability. I've also picked up a Generac 7000EXL that works well.
