I'm trying to trouble shoot an inoperative smoke unit on my UP SD90 #628274-I think this is a late 90s engine. I purchased it in 2009.
lionel does not have wiring schematics going back that far.
I found a previous post concerning AC voltage regulating and smoke unit. And it identifies what wires are what coming out of the voltage regulator. Does anybody know what voltages I should be seeing at those wires? Specifically what voltage should be coming out of the regulator and going into the smoke unit. Does the smoke unit run on full track power?
i'm also trying to figure out what input voltages I should be seeing at the smoke unit itself.
any help would be appreciated
