Reply to "AC voltage reg and smoke unit"

If it's a late 90's engine, it doesn't have a smoke regulator.  I don't find that number, is it part of a set?

I suspect it's the 2007 LionMaster that came in set 6-30051.

That unit has an 8 ohm smoke resistor, and most certainly does NOT run on track power directly!  You will see a few volts across the smoke resistor with smoke on, the exact value will depend on the meter you're using as it's not a pure sine wave.

The smoke regulator has five leads.  Sometimes one of the black ground leads is missing, they're connected to the same place.

• Brown: Serial Data from R2LC
• Brown with black stripe: Smoke Element Power
• Red: Track power
• Black: (two leads), frame ground

Edit: correct wire colors, OOPS!
