  I'm not sure what problem you are referring to.
The bulb (incandescent?) lights up, more and more,
as the speed increases.  Seems BAU to me.

Thanks
Any other suggestions are welcome.
I'm having him test the generator to see if it works fine under alternate power of another engine. Also mentioned to tighten up the belt or run it off the Flywheel.
Oddly enough, I've had several of these over they years but never ran one of them.

Take a look and let me know your thoughts.
It seems like the flywheel is slipping

My 15G generator would barely light the bulb when I first got it . I thought that was just the nature of the beast , and lived with it . In the end it turned out to be a bad ground , which, after tightening , worked correctly . I also replaced the large drive pully with a smaller 1/2" one, and now it will really light up the bulb , with fewer RPM's .

I would highly recommend using 2mm polyurethane belting with medium tension. It will not slip on the generator.

It may use tons of steam to power it, as stated with these turbines, but with proper tension you’ll get the generator to fly well. Also, I’d recommend using a E10 LED lightbulb. Order them on Amazon. They’re cheap and put less load on the system.  Can only be turned in one direction however.

Also, perhaps get a pressure guage and set your safety valve to pop around 25-30psi instead of the usual 15-20.

Thanks everyone. Great suggestions and information. My client is going to visit Jensen and let them check it out. 👍👍
I'll provide an update once it's figured out.
Have a great day

I’d say the steam nozzle is out of adjustment in some way. That’s turbine should spool up and whistle and pull that generator with no problem.
