We have a 6500kw yamaha diesel generator on our houseboat and lately it has been bogging down, for lack of a better term, intermittently for the past couple of weeks. I'm pretty sure its not because of a large draw off of it as it happens when we are just running lights, tv, and a ceiling fan. It will make the lights very dim for about 3 to 15 seconds and then they will come back up to their normal brightness. And this will happen every 5 or 10 minutes or so. It was suggested that it could be the brushes or bad diesel but i don't know much about these things. It has gotten somewhat better lately as we have been running it fairly regularly for the last couple of weeks. Any help would be greatly appreciated.
