I have a Bachmann 4-8-2 steamer that works very nicely but acts crazy when a TCS KA-1 is installed. The keep alive never seemed to work but after I did a decoder reset just trying anything to make it work now the engine will take off backwards until what must be the KA discharging. The faster I turn it on and off the less time it runs backwards as if the capacitor is less charged up. If I remove the KA the engine runs normally. I'm positive I have the KA connected to the correct points on the decoder as TCS has a picture on their web site showing the connection points. I'm at a loss for things to try and the main tech at TCS is out sick they say so I thought some of you guys might have a suggestion. Thanks Bill
If the KA1 is causing problems better to leave it off.
