It's the bridge rectifier that supplies power that causes the problem. The DC ground is not frame ground on all the new Lionel/ERR Sound board products. I presume the battery is connected to DC ground internally, but it really won't matter if we figure out an isolated supply scheme.

Well, if we knew for sure how the new Lionel/ERR stuff was wired, you might be able to do something like the attached. Note that the added rectifier parallels one of the rectifiers in the bridge.
