I did not use a TVS. I did not use a PTC. I don't even know what they are, but I am happy you do. I did use UPS to ship 15 engines back to Lionel, five of them for a second time, mostly mechanical or cosmetic issues. If these trains are so sensitive, why don't the manufacturers warn you not to buy them?
I use a ZW-L on a circuit breaker power strip and a 990 Remote. (Three of them, (not at the same time) all with mechanical issues, all going back to Lionel, two for a second time. The 990 Remote vibrates after I stopped my engine. The vibration turns the RED KNOB to speed 2 or 3 on its own, and the engine creeps forward.) It could be that the 990 Remote is sending power to an engine that doesn't have enough current to move, burning the board. Is this possible? I have all wires carefully running into MTH 1014 Boards that are daisy chained to my ZW-L with surge protection. What is a TVS and where should I install it? I have 500 wire drops from Atlas Terminal Joiners. I will NOT be adding 500 of anything to my layout. One , two, maybe. Please tell me where to "stick it", the TVS that is.
