I am new to the forum, have read posts but never posted. I have a problem with output voltage on my TIU. Have had this DCS unit for many years, but three days ago one of my four track zones started to have operating problems (power cutting in & out with dimming lights on & off ) After much time spent checking wire connections, with no success I decided to unplug all leads coming out of the TIU and check voltage coming out of each channel of the TIU. The voltage was 18 volts coming into each channel of the TIU and 18 volts coming out of three, but one variable channel had only .7 volts. What does this condition indicate? Looking for help with this issue!
