I got a nice Matrix T3X treadmill at a company cleanout.
Seems to be USA made, heavy, for up to 400 lb max runner weight,
with a US made Johnson 3HP motor etc.
Except that it sode not work and gives "Error 1". Some googling
revealed possible reason as "burnt brushes", so I took the brushes.
One of them was indeed burnt, as follows: evidence of heat damage, the
helical spring was no longer pushing it apart, and two out of three
strands of copper wire were burned.
The other brush was in a fine condition.
What I do not understand is how could only one brush burn out?
