Spectrum K4

[Penn1974]

I want to add bullfrog snot on my non-DCC K4 and do not know which wheels are the power pick up so as to not put it on those wheels. My tender does not have any wires to the locomotive.

The below link seems to indicate all the drivers pickup and transfer power to each frame half and then to each motor contact. Quite typical for Bachmann steam locos as I recall.

Pleas note, the lead and trailing trucks pickup power. Verify with your ohm meter.
