I have to replace a small ceramic disk capacitor and I am having trouble interpreting the markings. One side says B R010. The other side says 8192T. Any ideas?

Looks like a 10pf monolithic ceramic. I could be wrong.
Is it connected between motor chassis and a terminal ?

 

Its between the motor terminal and the lead that connects to it.

 

10 pF in the standard 3-digit European code, maybe, but I don't think that makes sense in this application. My first guess is 0.01 uF (10 nF), and a date code related to either 1981 or 1992.

Hello,

Its between the motor terminal and the lead that connects to it.

Does it mean that the component is in series with the powerlead?
Than it could be an inrush current suppressor.
A NTC could be used for this purpose.

If it is in series with the motor then it could be two things.
As @bertus said, a NTC.
Or a fuse.

{EDIT}
Wait.....may be a 0.01Ω Resistor

 

Hello,

As @R!f@@ said, it could also be a polyfuse, like this:

It looks perfectly healthy from here. What do you get for a resistance measurement?

 

I agree it does look healthy! To be honest, I am a mechanic, not so much an EE. All I know is motor no turny, but when I short out this component, motor turny. Interestingly, If i short it out and get the motor turning, it will continue to turn even if I stop shorting it out.

 

Sounds like it's stuck in high resistance mode, and that would indicate a surge suppressor, polyfuse, or NTC as previously speculated.
