Sawmill is down…. Y’all were right!
What happens here
The creator gathers a multimeter, jumper cables, an old battery, a sanding sponge, screwdrivers, pliers, and wrenches. He attempts to test the old motor using the jumper cables and battery, but it shows no sign of life. He then tests a new replacement motor, which spins perfectly. He decides to attempt repairing the old motor first, noting that a new motor costs $267 while a brush kit is only $40. He removes the motor's brush caps and extracts the corroded, stuck brushes, then applies penetrating oil to further loosen any internal corrosion.
Goal: Test the motor and begin the repair process by removing brushes
