Controlling engine speed

It's been awhile for me with a Powermaster, if I remember right there's a switch for command/conventional use.  Maybe you hit the switch?

Reprogram the PH-1 to "TR1" or track one.

Can you  set the stall speed in conventional using a power master? I forget?

You can indeed set the stall speed with a powermaster, but as already been mentioned, it sounds like the switch on the powermaster is in command mode.

Thanks for the replies. I've checked the Conv/Cmd switch and I have in the Conv mode. I've opened up the Powermast to see if their was a broken wire or something amiss but didn't see anything.  I'll try and set the stall speed with the powermaster. Thanks again.

The only other thing I can think of,when you turn the red knob do you the light flash on the base? Maybe the batteries are weak in the remote.

• The Powermaster is bad. The FET(s) went bad. It is repairable. Not sure of the part number but that is the symptoms. 

Unplug the  transformer that supplies power to the switches. Yeah I know but why not, It can't hurt.

I have a problem that is perplexing me in that I cannot control the locomotive speed with my CAB-1 remote. This is a new issue and it has become a problem because I haven't changed any wiring or configuration of my layout. Please note that I do not have any Command engines only traditional Lionel with Railsounds. When I place my Alco on the track it wants to go very fast and press "Boost" it want to run away and I have to grab it and take it off the track.  My new  Berkshire Jr. (6-38683 with tender) does something else. I will run a somewhat slower but I can't adjust the speed with my Cab-1, it doesn't seem to have any effect. My Alco did run off the track, causing the circuit breaker to trip but I don't think that would have anything to do with it's running only at top speed. Or would it? 

What I find perplexing is that this has just happened and both engines were running in normal mode just yesterday! Note, I only run one engine on the track at a time. My power is PH-1 plugged into a Powermaster.  I also have a Trainmaster with a wire from the U terminal to the U terminal on the Powermaster and this has worked fine until yesterday. My switches are controlled by a separate transformer via voltage plugs they work fine. This is a long sad take, but I would greatly appreciate any suggestions that may lead to a solution for what has been a real puzzle to me.  Thank you!

 

 

 

 

George, this may be a shot int the dark. CAB-1 operates at 27MHz which is where CB operates as well. CB operators are suppose to only transmit at 5 watts, but some are power hungry and will put a 12-1500 watt amp in-line. My point is that kind of wattage will mess with anything remotely close to 27MHz or anything thing close period. The best way to find out is turn on your stereo, if they come through your speakers there's your problem.
