Controller Problem
I have not run my Live Steam for a few years. When I switched on the controller, the loco started to heat up, but after a time, presumably until it reached pressure, the output voltage from the controller, which was steady at about 9v, suddenly switched off.
I waited a while to let the loco cool down, and tried again but, after the same time, it did the same thing.
As I am an electronics engineer, I would like to know more about how the system works:
Should the output voltage change with rotating the power lever (it did not)?
Should the voltage show a change when I flick the speed/direction lever (it did not)?
Does the loco send a signal to the controller when pressure is reached?
Is there a circuit diagram of the controller, and also of the loco?
What could cause the controller to shut down the output?
I would be grateful for any help you can offer me.
Hi David,
I have ordered a motor from Nick. He doesn't have any brushes. Any advice on how to do the replacemet (with pictures) would be helpful.
Re the reversing mechanism. To activate it, do you just run the motor down to zero speed or is there some other procedure?
Regards
