1) Check the connection blocks (wiring)
and for the presence of any
protruding/kinked terminals.
2) Check for the presence of any
marks/residue/water or detergent
deposits on the motor and where these
come from.
3) Proceed by checking for any
windings/earthed parts or parts with
poor earthing insulation. Use a tester
with a minimum capacity of 40 MΩ:
between each individual terminal and
the motor casing, read ∞ (fig.10).
4) Proceed by checking each individual
winding according to the following
table (fig.11).
