Bought used 50-1001 set and tried to add remote to TIU. If I'm connecting transformer to fixed voltage in 1,remote was added to unit and wasn't any problems to control engines.
if i'm connecting transformer to fixed voltage in 2 remote can't find TIU.
Same thing happen if i'm connecting transformer or to variable voltage in 1 or to variable voltage in 2.
What I'm doing wrong.
Thank you.
