Reply to "Supercap Question"

With regard to PS2, I am told that a failed white 8.4 volt battery will damage the board. I have no comment on PS1.

I have found that if one starts up a PS2 engine and immediately ups the speed from 0 and then the power cuts (as from a breaker opening), AND either the battery is dead or the supercap hasn't charged up, the engine ID may become garbled. I've had it happen on several occasions (grandkids will often shut down the layout after a derailment, without fixing it.).

I've changed all my PS2 locos to 3-volt boards and supercaps (2.5F, 5.4V as illustrated by the Gunrunner). The locos didn't get used enough to keep batteries adequately charged. If you use the locos regularly, batteries are fine. I've had MTH 2.4 volt packs last well over 10 years.
