Wonder if anyone has an idea about anything else I can try to get Variable 2 to work. TIU and all channels were working fine. There were a few blinks of the red light on the Z4000, no circuit breaker tripped, and after that I couldn't get Variable 2 to work On the layout the input to variable 2 was 20 volts and the output was only 8-10. Went to the test bench and got the same thing. Took the top off and pulled the fuse out and put one of the other channel fuses in and now basically no output from Variable 2. All fuses checked and are fine. All other channels have 19 volts in and 19 out. TIU is powered by an aux power source. Tried feature and factory resets.
