You cannot test or troubleshoot an un-loaded MY-9892 system. . Attempting to measure the output open-circuit with a digital multimeter will yield faulty, floating reading profiles near full line voltage. Always couple the terminal lines to a minimum 20W diagnostic bulb or alternative active element before testing. Thermal Design Considerations
