Reply to "Hornby Royal Scot 20 volt performance"

Question: Does the Hornby engine normally need to draw 3.5 amps at 20 volts? A Z-4000 will easily put out 20 volts at 3.5 amps (about 70 watts) without exceeding the available wattage for one throttle. Thus the need for the M20 seems to be negated. More likely a motor field or armature issue, as discussed previously. GRJ at Henning's could diagnose and possibly repair your treasure if you feel you need professional service.
