These 2 movies shows you how I recommend thoroughly testing a treadmill motor and MCB.
This is also how my Engineers at northwick.eu perform onsite testing.
Note that this is a DC motor system - different rules apply for an AC system!
DO NOT try this at home as you will be in direct contact with mains voltage which can kill.
ALWAYS seek expert advice and only use suitably qualified technicians
