Do not leave an alkaline battery in there, it should only be used for bench testing. I've found dead charging circuits with an alkaline battery in the locomotive, I tend to think the two events may be connected.
I don't want to jinx myself here, but the only engine I have ever had the electronics die was my first modern engine I ever bought, a mth ps2 Railking, and I had left a 9V alkaline in it.
