I’ve been looking for this thread for awhile and I have a TPC issue similar to George. I’ve had my TPC 400 connected (2 TPC 400’s In series) to my layout for many years and I gave it an ID Eng 4. It’s connected properly and simply quit. The light on the right blinks fine but it will not power up. Do they actually go bad? I also bought one from a forum member, TPC 400 and it does the same thing. I took them out of the layout, set up a Legacy system on my work table, connected 2 180 watt bricks, wired correct and neither TPC worked. Now when I begin programming them the light on the left gives a quick blink and does not come back on. I may have missed the step of Aux1, Aux2, 0.....So, I did place the new 360 Watt Legacy Powermaster in its place and it works fine, problem could be solved, However, I like the way TPC’s work better.
Question, who repairs these TPC’s? Question 2, does the TPC need to be programmed with a Cab 1?
Thank you for reviewing my questions, Leapin Larry
