I need some help/advice.
I have 4 TPC-400's connected to 4 180-Bricks connected to a modern ZW. All four are daisy chained, most often used in command mode with a Legacy Base/remote and run a decent sized layout.
I have had these for over 10 years and never had a problem...until now. Shortly after powering up they all just shut off. I do have a lot of engines on the layout but they are not even powered up before the TPC's shut off! I try to turn them back on pressing the red reset buttons on both the bricks and the TPC's. The bricks come back on, but not the TPC's ... unless I let them sit for unpowered 20 minutes they will eventually turn back on but after only after being on for a few minutes they shut back off! I noticed the TPC that runs the passenger terminal felt a little warm but only two block sidings with passenger cars were powered...surely that was not a huge load to override 1 tpc.
Yes, I did reprogram all 4 TPC and got the same result mentioned above!
Is it common for this type of equipment to just start "failing"?
Any help is greatly appreciated.
Thanks,
Greg
