I bought a used Yamaha ef4500ise genny for my camper with 80 hrs on it. I put 15 hrs on it, and it worked fine. Now all of a sudden when I turn it on, it's continues to run(good idle) but only produces power for 30 seconds or so, then the overload light comes on. This is with no load on it. I've cleaned the air filters and changed the spark plug and nothing. Someone please give me some good news(easy fix). It'll **** that i just gave $1500 for this genny for 15 hrs of use. Thank you in advance.

It was a bent pin. It had a recall for the carburator, when it was replaced, the dealer bent some of the pins that connected to the idle. Therefore it was running high idle(pushing 300amps) and overloaded immediately. The pins were replaced and everything works better than it did originally. I'm thinking the guy that sold it to me thought it was toast and tryed to screw me, little did he know, it was covered by warranty still and didn't cost me a penny. Yamaha is good to go.
