I need to know if anyone has installed a dimmer switch so that the voltage can be reduced. I purchased a Bridgewerks Magnum 15SR which is what MTH showed in there literature. However, they now tell me that using it will damage my trains. They recommend puting in a dimmer switch to lower the voltage, but they would not send me a diagram as to the correct way to wire the unit. Any help would be appreaciated.
