Hi All,

Has anyone seen this before?  I just bought these and I'm nervous to use them with that kind of seepage/corrosion.  Should I be concerned or not?


I think you'll have to open them before installing them. Check the inside of the motor wheels.
Here you have pictures of the new condition of the inside of the motor-wheels.
If there has been oxidation of the copper coils, perhaps due to water infiltration, you will see it immediately.
