Operation AUTO TURN ON INPUT LEVEL +12V DC AUDIO LO OFFSET HI L FADER ON OFF R L RED Badge Light off, no output? With a Volt Ohm Meter (VOM) check the following: 1) +12 volt power terminal (should read +12V to +16V) 2) Remote turn-on terminal (should read +12V to +16V) 3) Check for reversed power and ground connections. 4) Ground terminal, for proper conductivity. 5) Check for blown fuses.
