Electrical Help Needed - How to figure out how many watts a Lionel 167 whistle controller draws.
I was wondering if someone could give me an idea of what is happening on my Lionel layout,
I would like to understand what is needed to calculate the volts & watts needed for my set up.
I asked for help at the 2 local train shops and the only advise I was given was to "just buy a bigger ZW style transformer."
My question concerns a #167 lionel whistle controller, a 90 Watt type A transformer and a pair of O22 switches.
My temporary layout is about 3x8 or 4x6 and only has a O gauge loop with a passing siding, I have 6 feeder lock ons and clean tight track with 1 RCS uncoulpler section.
I'm running a 1947 675 and a 1949 671 turbine (only one engine is on the tracks at a time), both engines run OK with no whistle controller hooked up to the B&U posts as per the lionel instructions, With the 167 controller hooked up correctly Both engines run slower and slow way down with the Whistle button pushed, the whistles both work.
My 1947 catalog and instructions show this type of transformer & whistle controller running a much bigger layout than what I have. Everything is wired correctly.
I have tried a 2nd different Type A transformer, and 4 different 167 whistle controllers, all 4 controllers will blow a whistle fine while the train is stationary.
I would like to find out how many watts are needed to run this set up, Is 90 watts too small for what I have? How would I determine the wattage needed?
Is the Lionel directions incorrect about the use of this style transformer and whistle controller?
Also is there a way to figure out how many watts a 167 whistle controller draws? I can tell that all the 167s I have all use about 6-8 volts when hooked up.
I belive it is a choke coil inside that holds back some voltage untill the whistle button is pressed and then the DC pulse and a bypass of the coil gives a slight voltage boost to compensate for the whistle motor. Correct?
I really like the look of the early postwar transformer it came with the original set I have, I dont want to buy a newer ZW if I dont have to, I considered a Z for the higher watts and 2 train control but I dont want to transfer the whistle controller problem to a 3rd transformer.
I'm confused as what to do next for a power supply. Any help or advise would be appreciated.
