N Scale GP40 Goes Way too Fast

[Lds760]

Sorry, total newbie, but I have an N Scale Freightmaster set that came with a CEC wall pack with speed controller.  The thing flies around the track at the slowest setting and barely changes if I turn the knob.  How can I slow it down?  Thanks.

Unless you want to return the whole set, you will need to isolate the problem.  It sounds to me like the problem is in your speed controller, not the locomotive.  See if you can borrow another N-scale locomotive and see how it performs.  If it runs too fast also, the problem is in your speed controller.

Another way would be to hook a voltmeter to the rails to see what amount of voltage your pack is putting out at different throttle settings.  I'd say you probably have a defective throttle.

You probably have the track connected to AC power. Connect it to the DC power, and it should work properly.

I disagree.  If you hooked the rails to the AC side, the loco would just sit and hum and burn out.

You are correct.
