I have a Generac 6500EXL 15 yrs old which stopped producing electricity during the last power outage. I brought it in for service and they replaced the power regulator board and indicated the engine needed some service but they didn't do engine work. So I brought it directly to the engine guys for a tune-up. I bring the generator home and start it up. It starts up quickly but within 3 minutes I see white smoke that appeared to be coming from the muffler and I thought it would just burn off. About a minute later it became clear that the smoke was coming from within the alternator and getting heavier. Then I noticed the smoke was also coming from the the control panel and its on board electrical outlets and the panel was very hot. I shut the motor and now it won't even attempt to start with the start button. I already invested alot of money in these 2 repairs and am not sure what to do next. I am afraid it was damaged significantly and don't know if it could have been due to a defective replacement power regulator, something that was done during the tune-up or some new problems. The problem seem to have originated in the alternator since that's where the smoke started first. Any ideas would be appreciated.

Did you run it after you got it back from the first repair? I would guess it was the first guy that worked on the generator but you need to find out what the engine guy did. I would ask the engine guy what exactly he did and have him document his work. Then talk to the generator guy and see what he will do but it sounds like a expensive repair.

Thanks Bob. Because it is so heavy and difficult for me to transport I decided to bring it for the engine work directly. In hindsight I think a bad idea! I have since removed the back cover on the alternator and see that the wires burned. At least two of them have no insulation and others are badly damaged. One of the wires leading up to the control panel was burned through and it looks like the fire progressed from the alternator up the wiring harness to the control panel. I also see the replacement power regulator which still looks brand new and I don't see any damage with its wires. Unfortunately I think I am out the money for the repairs and need to buy a new generator. Being in Connecticut they are almost non-existent right now which is why I attempted to have it repaired in the first place.

Ziller Electric ships nationwide and can probably fix you right up. I have only read great things about these people and if I had it to do over I would have ordered mine from them to say thanks for this great forum.

I assume the generator guy test ran it after he replaced the regulator and will say it ran fine when it left here and will point a finger at the engine guy and say he did something to it. It almost sounds like you are going to better off with a new rig rather than try to fix it again and hope it works.

That's what I think as well, its unfortunate. I have just sent an email to Ziller to see if we can work something out. I do appreciate all the advice here.
