Hi all,
Please be gentle, this is my first post.
I've just bought a second-hand-but-never-run MTH Challenger, and want to convert it to battery power.
It is lovely, especially when I got the sound to work, the main connector inside had come loose inside.
My question is - some of you have already done this type of conversion, so what type of power controller do you use from the battery?
The reason I ask is that the loco seems to have its own on-board controller with presumabably some form of PWM.
It runs perfectly well from my LGB 51070 controller, first the lights and sound come on fully, then a bit more power and it actually starts to move.
However, is it just expecting to see a smooth DC voltage, and set its speed from the voltage?
This would mean a 'simple' voltage controller could be used, rather than a PWM type.
