New rheostat on the way. In the mean time, we took a trip down the Hudson River corridor!

Kind of lucky the rheostat even turned on and off.

Re: Hello from Boston
BTW a correct rheostat for this application is not likely to be closed back as that one was. Your burnt up rheostat was probably to small which is why you found it in the condition you did. Your replacement will likely have an open element.

Re: Hello from Boston
How expensive is a new one?
I wonder if you could get that one re-wound.

It had no markings on it so I don't know the specs, but it does look almost identical to this one:

Re: Hello from Boston
After we opened it and poked it, the insides sort of just crumbed to dust. A new one was only $35. I went with a 25W, 100 Ohm, open backed version that was recommended elsewhere on the forum. We'll see how that goes

Re: Hello from Boston
This is what they look like:
But looks are not important. What is important is that the rheostat is sized correctly for the load in the circuit it is installed in. The number of and type of bulbs in the circuit determine the load. This is why you don't want to change bulbs, add or subtract bulbs willy nilly to this circuit.

That trip down the Hudson looks great and you could see where Sully put the plane.

Re: Hello from Boston
Doubtful it will work well, Christine. I got one with those specs at first and it only acted as a switch, sort of.rusbac wrote:After we opened it and poked it, the insides sort of just crumbed to dust. A new one was only $35.

I ended up getting this one from Aircraft Spruce.

I'm pretty sure it's the 0-15ohm version. I can check later today.
