4 1 Motors 1.1 Procedure for checking motors 1) Check the connector blocks (wiring) and check for detached or bent terminals. 2) Check for traces, residue or deposits of water or detergent on the motor and identify the source. 3) Check for windings or other parts that may be grounded or poorly insulated. Use a tester with a minimum scale of 40 MΩ: between each terminal and the casing, this should read. 4) Check each winding against in Ω values shown in the tables below. 1.2 Universal motors (with 10-terminal connection box) MOTORS TERMINALS ON MOTOR TERMINAL BLOCK CHECKS C.E.SET.
