Zebra Instruments Variable Speed Zebra - Comprehensive Mircoprocessor Tool for ECM System Diagnostics and Analysis. VZ-7 is a microprocessor-controlled diagnostic tool that performs sophisticated testing with only 4 switches.
GE, who makes a large share of these motors, reports that 41% of the motors returned to their factory actually have "no problem found". That means someone made an expensive mis-diagnosis; it also meand the real problem has not been corrected by replacing the motor. Almost any mistake in diagnosis on an ECM system will cost much more than this tool does!
Two DVDs are included; one that teaches Variable Speed System Theory, the second instructs the Tech how to use the VZ-7 to troubleshoot these systems.
